From Mark Judge:
Saint Paint Studio is a paint package designed to be the essential base tool for editing photos, Web graphics, icons, images, and animations. Developed initially for use in the games industry, it comes with the most vital tools needed by professional artists, designers, and programmers, but is suitable for users with any level of experience. It's also extremely well suited to making fun, doctored photos. Many file formats are supported, including GIF, JPEG, BMP, ICO, TGA, and AVI. When saving, each format's attributes are fully explained to avoid loss of image quality. Among its many features are animation editing; layers and alpha channels; batch-image conversion; photo sharpening, blurring, embossing, and despeckling; a red-eye filter; controls for brightness, contrast, and gamma; image resizing; color reduction; a full set of essential color-palette-manipulation features for true-color, 256-color, 16-color, and 2-color.
