For Commercial and Educational licenses there is a limit of 2 active blocks at a resolution 1920x1080.\nNote: CodeMeter Runtime v7.60+ is now required to load Notch blocks. \nLoading the Notch Block into the Notch will generate custom parameters for all the exposed properties in the block. They are split up by page, with each page representing a layer of the block. The output layer can be selected using the 'Layer' parameter.\nThe custom parameter labels will be generated using the Exposed Name of the exposed property with any special characters or spaces removed. If the Unique Identifier is custom (and not the default auto-generated value) then it will be used as the name of the custom parameter instead. Using a custom Unique Identifier on all exposed properties is recommended for TouchDesigner.\nEnabling Debug Logging: To diagnose issues with Notch blocks, you can enable logging by setting a Windows Environment variable TOUCH_NOTCH_LOGGING=1.\nSee also: Notch\nnotchTOP_Class\n\nContents\n \n \n \n \n \n \n \n\n\n\n\n\n active - The active state of the node/block. When active, the node will actively render the block. If disabled, the node will release its instance of the block, and unload it if there are no other instances (ie. no other Notch TOPs with the same block). This will allow the block (.dfxdll) to become editable again. If re-activated, the block will be reloaded along with any changes.\n\n\n\n clearparams - When enabled, all parameters will be cleared. When disabled, it will keep parameter values for exposed parameters of the same name when the Notch Block file changes.\n\n\n\n block - Specify the .dfxdll file (ie. Notch Block).\n\n\n\n layer - The layer used as the output to the Notch .\n\n\n\n playmode - - A menu to specify the method used for playback of the block.\n\n lockedtotimeline - This mode locks the animation position to the timeline. specifyindex - This mode allows the user to specify a particular index (position) in the animation using the Index parameter below. sequential - This mode plays continually.\n\n init - Initialize the playback of the block. This will reset it to the start, but not move forward with playback.\n\n\n\n start - Start the playback of the block. This will reset it to the start and begin playback.\n\n\n\n play - Enable playback of the block. When disabled and in Sequential mode the playback will be paused.\n\n\n\n speed - The speed of the playback.\n\n\n\n index - The index of the playback when Index mode is selected.\n\n\n\n indexunit - - Sets the units used in the Index parameter.\n\n samples - frames - seconds -\n\n purge - Purge Video RAM used by the block.\n\n\n\n\n\n outputresolution - - quickly change the resolution of the 's data.\n\n useinput - Uses the input's resolution. eighth - Multiply the input's resolution by that amount. quarter - Multiply the input's resolution by that amount. half - Multiply the input's resolution by that amount. 2x - Multiply the input's resolution by that amount. 4x - Multiply the input's resolution by that amount. 8x - Multiply the input's resolution by that amount. fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same. limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same. custom - Directly control the width and height.\n\n resolution - - Enabled only when the parameter is set to Custom . Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.\n\n resolutionw - resolutionh -\n\n resmenu - A drop-down menu with some commonly used resolutions.\n\n\n\n resmult - Uses the Global Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this is affected by the global multiplier.\n\n\n\n outputaspect - - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)\n\n useinput - Uses the input's aspect ratio. resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square. custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.\n\n aspect - - Use when Output Aspect parameter is set to Custom Aspect.\n\n aspect1 - aspect2 -\n\n armenu - A drop-down menu with some commonly used aspect ratios.\n\n\n\n inputfiltertype - - This controls pixel filtering on the input image of the .\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. This is how you get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.\n\n fillmode - - Determine how the image is displayed in the viewer.\nNOTE:To get an understanding of how TOPs work with images, you will want to set this to Native as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.\n\n\n useinput - Uses the same Fill Viewer settings as it's input. fill - Stretches the image to fit the edges of the viewer. width - Stretches image to fit viewer horizontally. height - Stretches image to fit viewer vertically. best - Stretches or squashes image so no part of image is cropped. outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer. nativeres - Displays the native resolution of the image in the viewer.\n\n filtertype - - This controls pixel filtering in the viewers.\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. Use this to get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).\n\n npasses - Duplicates the operation of the the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected 's image.\n\n\n\n chanmask - Allows you to choose which channels (R, G, B, or A) the will operate on. All channels are selected by default.\n\n\n\n format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.\n\n useinput - Uses the input's pixel format. rgba8fixed - Uses 8-bit integer values for each channel. srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB. rgba16float - Uses 16-bits per color channel, 64-bits per pixel. rgba32float - Uses 32-bits per color channel, 128-bits per pixels. rgb10a2fixed - Uses 10-bits per color channel and 2-bits for alpha, 32-bits total per pixel. rgba16fixed - Uses 16-bits per color channel, 64-bits total per pixel. rgba11float - A RGB floating point format that has 11 bits for the Red and Green channels, and 10-bits for the Blue , 32-bits total per pixel (therefore the same memory usage as 8-bit RGBA). The Alpha channel in this format will always be 1. Values can go above one, but can't be negative. ie. the range is [0, infinite). rgb16float - rgb32float - mono8fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 8-bits per pixel. mono16fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono16float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono32float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 32-bits per pixel. rg8fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 8-bits per channel, 16-bits total per pixel. rg16fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg16float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg32float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 32-bits per channel, 64-bits total per pixel. a8fixed - An Alpha only format that has 8-bits per channel, 8-bits per pixel. a16fixed - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a16float - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a32float - An Alpha only format that has 32-bits per channel, 32-bits per pixel. monoalpha8fixed - A 2 channel format, one value for RGB and one value for Alpha. 8-bits per channel, 16-bits per pixel. monoalpha16fixed - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha16float - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha32float - A 2 channel format, one value for RGB and one value for Alpha. 32-bits per channel, 64-bits per pixel.\n\n\n\nExtra Information for the Notch can be accessed via an Info CHOP.\n\n\n - - - - - - - - - - - - - -\n - Horizontal resolution of the in pixels. - Vertical resolution of the in pixels. - Horizontal aspect of the . - Vertical aspect of the . - Depth of 2D or 3D array if this contains a 2D or 3D texture array. - Total amount of texture memory used by this .\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditorwikieditorwikieditorwikieditorwikieditorwikieditor2021.100002020.20000before 2020.20000\nTOPs\n• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • \n\nAn Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network.

"description": "NOTE\n\nLicense: Only available in TouchDesigner Educational, TouchDesigner Commercial and TouchDesigner Pro.OS: This operator is only supported under the Microsoft Windows operating system.\n\n\nThe Notch will load a Notch Block (extension .dfxdll) compiled from Notch Builder. For Commercial and Educational licenses there is a limit of 2 active blocks at a resolution 1920x1080.\nNote: CodeMeter Runtime v7.60+ is now required to load Notch blocks. \nLoading the Notch Block into the Notch will generate custom parameters for all the exposed properties in the block. They are split up by page, with each page representing a layer of the block. The output layer can be selected using the 'Layer' parameter.\nThe custom parameter labels will be generated using the Exposed Name of the exposed property with any special characters or spaces removed. If the Unique Identifier is custom (and not the default auto-generated value) then it will be used as the name of the custom parameter instead. Using a custom Unique Identifier on all exposed properties is recommended for TouchDesigner.\nEnabling Debug Logging: To diagnose issues with Notch blocks, you can enable logging by setting a Windows Environment variable TOUCH_NOTCH_LOGGING=1.\nSee also: Notch\nnotchTOP_Class\n\nContents\n \n \n \n \n \n \n \n\n\n\n\n\n active - The active state of the node/block. When active, the node will actively render the block. If disabled, the node will release its instance of the block, and unload it if there are no other instances (ie. no other Notch TOPs with the same block). This will allow the block (.dfxdll) to become editable again. If re-activated, the block will be reloaded along with any changes.\n\n\n\n clearparams - When enabled, all parameters will be cleared. When disabled, it will keep parameter values for exposed parameters of the same name when the Notch Block file changes.\n\n\n\n block - Specify the .dfxdll file (ie. Notch Block).\n\n\n\n layer - The layer used as the output to the Notch .\n\n\n\n playmode - - A menu to specify the method used for playback of the block.\n\n lockedtotimeline - This mode locks the animation position to the timeline. specifyindex - This mode allows the user to specify a particular index (position) in the animation using the Index parameter below. sequential - This mode plays continually.\n\n init - Initialize the playback of the block. This will reset it to the start, but not move forward with playback.\n\n\n\n start - Start the playback of the block. This will reset it to the start and begin playback.\n\n\n\n play - Enable playback of the block. When disabled and in Sequential mode the playback will be paused.\n\n\n\n speed - The speed of the playback.\n\n\n\n index - The index of the playback when Index mode is selected.\n\n\n\n indexunit - - Sets the units used in the Index parameter.\n\n samples - frames - seconds -\n\n purge - Purge Video RAM used by the block.\n\n\n\n\n\n outputresolution - - quickly change the resolution of the 's data.\n\n useinput - Uses the input's resolution. eighth - Multiply the input's resolution by that amount. quarter - Multiply the input's resolution by that amount. half - Multiply the input's resolution by that amount. 2x - Multiply the input's resolution by that amount. 4x - Multiply the input's resolution by that amount. 8x - Multiply the input's resolution by that amount. fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same. limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same. custom - Directly control the width and height.\n\n resolution - - Enabled only when the parameter is set to Custom . Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.\n\n resolutionw - resolutionh -\n\n resmenu - A drop-down menu with some commonly used resolutions.\n\n\n\n resmult - Uses the Global Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this is affected by the global multiplier.\n\n\n\n outputaspect - - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)\n\n useinput - Uses the input's aspect ratio. resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square. custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.\n\n aspect - - Use when Output Aspect parameter is set to Custom Aspect.\n\n aspect1 - aspect2 -\n\n armenu - A drop-down menu with some commonly used aspect ratios.\n\n\n\n inputfiltertype - - This controls pixel filtering on the input image of the .\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. This is how you get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.\n\n fillmode - - Determine how the image is displayed in the viewer.\nNOTE:To get an understanding of how TOPs work with images, you will want to set this to Native as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.\n\n\n useinput - Uses the same Fill Viewer settings as it's input. fill - Stretches the image to fit the edges of the viewer. width - Stretches image to fit viewer horizontally. height - Stretches image to fit viewer vertically. best - Stretches or squashes image so no part of image is cropped. outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer. nativeres - Displays the native resolution of the image in the viewer.\n\n filtertype - - This controls pixel filtering in the viewers.\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. Use this to get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).\n\n npasses - Duplicates the operation of the the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected 's image.\n\n\n\n chanmask - Allows you to choose which channels (R, G, B, or A) the will operate on. All channels are selected by default.\n\n\n\n format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.\n\n useinput - Uses the input's pixel format. rgba8fixed - Uses 8-bit integer values for each channel. srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB. rgba16float - Uses 16-bits per color channel, 64-bits per pixel. rgba32float - Uses 32-bits per color channel, 128-bits per pixels. rgb10a2fixed - Uses 10-bits per color channel and 2-bits for alpha, 32-bits total per pixel. rgba16fixed - Uses 16-bits per color channel, 64-bits total per pixel. rgba11float - A RGB floating point format that has 11 bits for the Red and Green channels, and 10-bits for the Blue , 32-bits total per pixel (therefore the same memory usage as 8-bit RGBA). The Alpha channel in this format will always be 1. Values can go above one, but can't be negative. ie. the range is [0, infinite). rgb16float - rgb32float - mono8fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 8-bits per pixel. mono16fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono16float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono32float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 32-bits per pixel. rg8fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 8-bits per channel, 16-bits total per pixel. rg16fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg16float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg32float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 32-bits per channel, 64-bits total per pixel. a8fixed - An Alpha only format that has 8-bits per channel, 8-bits per pixel. a16fixed - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a16float - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a32float - An Alpha only format that has 32-bits per channel, 32-bits per pixel. monoalpha8fixed - A 2 channel format, one value for RGB and one value for Alpha. 8-bits per channel, 16-bits per pixel. monoalpha16fixed - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha16float - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha32float - A 2 channel format, one value for RGB and one value for Alpha. 32-bits per channel, 64-bits per pixel.\n\n\n\nExtra Information for the Notch can be accessed via an Info CHOP.\n\n\n - - - - - - - - - - - - - -\n - Horizontal resolution of the in pixels. - Vertical resolution of the in pixels. - Horizontal aspect of the . - Vertical aspect of the . - Depth of 2D or 3D array if this contains a 2D or 3D texture array. - Total amount of texture memory used by this .\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditorwikieditorwikieditorwikieditorwikieditorwikieditor2021.100002020.20000before 2020.20000\nTOPs\n• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • \n\nAn Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network.
