PNG images that contain grayscale or color data that has been sampled at a rate between 8 and 16 bits per sample may also contain an alpha channel(also called an alpha mask), which is an additional 8 to 16 bits (depending on the image color depth) that represents the transparency level...

PNG/fpnge (veluca93/fpnge) is a very fast PNG encoder. The repository only contains an encoder, not a decoder. It's also currently only SIMD-optimized for the x86 CPU family, not ARM. PNG/libpng is the official libpng library as built on Debian Bullseye. ...
In Core Image, you can use theinit(color: CIColor)initializer ofCIImageto create an image with infinite extent that only contains pixels with the given color. This, however, only allows the creation of images filled with values in [0…1] sinceCIColorclamps values to this range. ...
The image renderer format object contains properties that determine the attributes of the underlying Core Graphics contexts that the image renderer creates. Use thedefault()class method to create an image renderer format instance optimized for the current device. ...
Computes an arbitrary rectangular region of the BufferedImage and copies it into a specified WritableRaster. Graphics2D createGraphics() Creates a Graphics2D, which can be used to draw into this BufferedImage. WritableRaster getAlphaRaster() Returns a WritableRaster representing the alpha channel for...
