GafferImage Nodes
| Name | Description |
|---|---|
| Name | Description |
| Anaglyph | Converts a multi-view image with “left” and “right” views into a single view image with the two views combined in different colors, suitable for viewing through red-blue anaglyph glasses. |
| BleedFill | Fills in areas of low alpha in the image by blurring in contributions from nearby pixels. |
| Blur | Applies a gaussian blur to the image. |
| Catalogue | Stores a catalogue of images to be browsed. Images can either be loaded from files or rendered directly into the catalogue. |
| CatalogueSelect | Finds an image in a directly connected Catalogue by name. |
| CDL | Applies color transformations provided by OpenColorIO via an OCIO CDLTransform. |
| Checkerboard | Outputs an image of a checkerboard pattern. |
| Clamp | Clamps channel values so that they fit within a specified range. |
| CollectImages | Forms a series of image layers by repeatedly evaluating the input with different Contexts. Useful for networks that need to dynamically build an unknown number of image layers. |
| ColorSpace | Applies colour transformations provided by OpenColorIO. Configs are loaded from the configuration specified by the OCIO environment variable. |
| Constant | Outputs an image of a constant flat colour. |
| ContactSheet | Assembles multiple input images into a tiled grid, with customisable layout, labels and borders. |
| ContactSheetCore | Collects multiple input images, transforming them into tiles within the output image. Provides the core functionality of the ContactSheet node, and may be reused for making similar nodes. |
| CopyChannels | Copies channels from the secondary input images onto the primary input image and outputs the result. |
| CopyImageMetadata | Copies metadata entries from the second image to the first image based on name. |
| CopyViews | Copies views from the secondary input images onto the primary input image. |
| CreateViews | Creates a multi-view image by combining multiple input images. |
| Crop | Modifies the Data and/or Display Window, in a way that is either user-defined, or can be driven by the existing Data or Display Window. |
| DeepHoldout | Flattens the part of the input which is not hidden by the holdout input. |
| DeepMerge | Merges the samples from two or more images into a single deep image. |
| DeepRecolor | Recolors deep data so that the flattened image will match the color of a provided flat image. |
| DeepSampleCounts | Outputs an image showing the deep sample counts for each pixel. |
| DeepSampler | Samples the full channel data of an image at a specified pixel location, including all deep samples. |
| DeepSlice | Takes a slice out of an image with depth defined by Z (and optionally ZBack) channels by discarding everything outside of a clipping range. The range is half open, including point samples exactly at the near clip, but excluding point samples exactly at the far clip. This means that if you split an image into a front and back with two DeepSlices, they will composite back together to match the original. |
| DeepTidy | Ensures deep samples are sorted and non-overlapping, and optionally discards samples that are completely transparent, or covered by other samples. |
| DeepToFlat | Converts a deep image into a “flat” image, by compositing all samples in each pixel, resulting in an image with 1 sample for every pixel. |
| DeleteChannels | Deletes channels from an image. |
| DeleteImageMetadata | Deletes metadata entries from an image based on name. |
| DeleteViews | Deletes views from an image. |
| Dilate | Applies a dilate filter to the image. |
| DisplayTransform | Applies an OpenColorIO display transform to an image. |
| Erode | Applies an erode filter to the image. |
| FlatToDeep | Sets the deep flag on a flat image, and makes sure that it has a Z channel ( and optionally a ZBack channel ) so that it can be used in deep compositing. |
| FormatQuery | Extracts the format of an input image, for driving the format input of another image node, or driving expressions. |
| Grade | Performs a simple per-channel colour grading operation. |
| ImageMetadata | Adds arbitrary metadata entires to an image. |
| ImageReader | Reads image files from disk using OpenImageIO. |
| ImageSampler | Samples image colour at a specified pixel location. |
| ImageStats | Calculates minimum, maximum and average colours for a region of an image. |
| ImageTransform | Scales, rotates and translates an image within its display window. |
| ImageWriter | Writes image files to disk using OpenImageIO. |
| LookTransform | Applies OpenColorIO “looks” to an image. |
| LUT | Applies color transformations provided by OpenColorIO via a LUT file and OCIO FileTransform. |
| Median | Applies a median filter to the image. |
| Merge | Composites two or more images together. |
| MetadataOverlay | Formats metadata into a text overlay on top of the image. Provides control over formatting, font, layout and a drop shadow. |
| Mirror | Mirrors the image, flipping it in the horizontal and/or vertical directions. This performs no filtering, so pixel values are not changed. |
| Mix | Blends two images together based on a mask. |
| Offset | Translates the image in integer increments. No filtering is necessary, and this node has improved performance compared to the equivalent ImageTransform. |
| OpenColorIOContext | Creates Gaffer context variables which define the OpenColorIO config to be used by upstream nodes. |
| Premultiply | Multiplies selected channels by a specified alpha channel. |
| Ramp | Outputs an image of a color gradient interpolated using the ramp plug. |
| Rectangle | Renders a rectangle with adjustable line width, corner radius, drop shadow and transform. |
| Resize | Resizes the image to a new resolution, scaling the contents to fit the new size. |
| Saturation | Increases or decreases the saturation of an image. |
| SelectView | Picks one view from a multi-view image and outputs it as an image with a single, default view. |
| Shuffle | Shuffles data between image channels, for instance by copying R into G or a constant white into A. |
| ShuffleImageMetadata | Shuffles image metadata, allowing entries to be copied and/or renamed. |
| Unpremultiply | Divides selected channels by a specified alpha channel. |
| VectorWarp | Warps an input image onto a set of UVs provided by a second image, effectively applying a texture map to the UV image. |
