libPGF contains an implementation of the Progressive Graphics File (PGF). which is a new image file format, that is based on a discrete, fast wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression.
A PHP 7 library for working with RGB, HSL, and Hexadecimal colors. Create schemes, modify specific color properties, export CMYK, and make color suggestions quickly and easily with this stand-alone library.
This project was first created on picture graphic processing basics labs. It only shows some simple implementation of basic features that all modern graphic utilities like Gimp have.
The recent version of the project has been optimized to work with CUDA.
Duotoner's key purpose is to convert a full-colour image into a 2-channel image, suitable for reproduction with black ink and a single spot colour. The resulting image is saved as a CMYK image; the idea is that whichever of the three colour channels, C, M or Y is "dominant" will carry the actual
... [More] colour information, and when printing, you'll replace that plate with the spot ink. The two unused channels will nonetheless carry "plausible" colours, so the DuoTone image can be used for proofing.
If, for example, you're separating to black and red, the red information will end up in both the Magenta and Yellow channels. When doing the actual print run you'd only use one of these two plates, and replace the ink with spot red - but printing a proof on a CMYK printer will still give a plausi [Less]
