Text functions offer the capability to write single and multiple lines of text and include location, alignment, font family, font size, font style, text color, translucent text (watermark), angle rotation, background color (which can be semi-transparent), texture text drawing and more.

These functions provide image color conversion from / into a 1-bit, 4-bit, 8-bit, 16-bit, 24-bit, 32-bit, 48-bit, 64-bit and 128-bit depth.

These functions can calculate the optimum color palette for a 4-bit or an 8-bit image using octree color quantization algorithms. You can use a standard color palette, or apply a custom or existing color palette:

Convert a 24-bpp jpeg image into a gif image for web with optimum 8-bpp color palette.
Convert a 24-bpp jpeg photo into an 8-bpp grayscale J2K image.
Convert a 1-bpp bitonal image into an 8bpp grayscale image.

Dithering algorithms such as Stucki, Floyd Steinberg & Burke are implemented to improve the color conversion.

GdPicture SDKs feature a set of high-level APIs that enable you to handle and edit pages/frames in a multi-page TIFF image and in an animated GIF image.
These functions make it possible to access, extract, swap, insert and delete pages/frames in these types of images.

They also include functions to split and merge multi-page image files:

Merge two multi-page TIFF images into one multi-page TIFF / animated GIF file.
Merge a jpeg file, a png file and a J2K file into one multi-page TIFF file / animated GIF file.
Extract all pages or a specific page of a multi-page TIFF / animated GIF image as a single TIFF / GIF file(s)...


All of this can be done with a minimum amount of code and a low requirement of CPU & memory usage.
