Interface ImageTransform
access this type via: media.image.ImageTransform (provides, requires or uses)
This API supports common transform functions for images.
Functions
ImageTransform(WH outputSize)
PixelMapYUV rgbaToYUV(PixelMap p, optional byte pixelFormat)
PixelMap yuvToRGBA(PixelMapYUV p, optional ChromaKeySpec spec)
PixelMap crop(PixelMap p, int x, int y)
PixelMap chromaKey(PixelMap p, ChromaKeySpec spec, optional byte pixelFormat)
PixelMap runAlphaMask(PixelMap p, byte mask[], optional byte pixelFormat)
ImageTransform(WH outputSize)
Create a new image transform instance. This instance will only be capable of outputting pixel maps of the given size.
PixelMapYUV rgbaToYUV(PixelMap p, optional byte pixelFormat)
Convert an RGBA image to YUV.
PixelMap yuvToRGBA(PixelMapYUV p, optional ChromaKeySpec spec)
Convert a YUV image to RGBA.
PixelMap crop(PixelMap p, int x, int y)
Crop an image, by identifying a rectangle within that image. The identified rectangle is extracted as a new image and returned.
PixelMap chromaKey(PixelMap p, ChromaKeySpec spec, optional byte pixelFormat)
Set pixels matching the given colour to be transparent.
PixelMap runAlphaMask(PixelMap p, byte mask[], optional byte pixelFormat)
Apply a run-length-encoded mask to the pixels.
