This is a simple library to load images of various formats as SDL surfaces.
This library supports BMP, PPM, PCX, GIF, JPEG, PNG, TGA, and TIFF formats.

Entangle is an application which uses GTK+3 and libgphoto2 to provide a
graphical interface for tethered photography with digital cameras.
It includes control over camera shooting and configuration settings and
"hands off" shooting directly from the controlling computer:
- Trigger the shutter from the computer
- Live preview of scene before shooting
- Automatic download and display of photos as they are shot
- Control of all camera settings from computer
The pixmap program is a tool for creating or editing rectangular images
made up of colored pixels, i.e., pixmaps. Pixmaps are intensively used in
X to define window backgrounds, icon images, etc.
png2html takes a PNG image and transforms it into a Web page with the
use of a text file.
Converts PNG files to Windows icon resource files.
pngcheck verifies the integrity of PNG, JNG and MNG files
(by checking the internal 32-bit CRCs [checksums] and decompressing
the image data); it can optionally dump almost all of the chunk-level
information in the image in human-readable form.
For example, it can be used to print the basic statistics about an image
(dimensions, bit depth, etc.); to list the color and transparency info
in its palette (assuming it has one); or to extract the embedded text
annotations. This is a command-line program with batch capabilities.
pngsplit - break a PNG, MNG or JNG image into constituent chunks
(numbered for easy reassembly)
png-fix-IDAT-windowsize - fix minor zlib-header breakage caused by
older libpng
pngcrush reads in a PNG image, and writes it out again, with the
optimum filter_type and zlib_level. It uses brute force (trying
filter_type none, and libpng adaptive filtering, with compression
levels 3 and 9). It does the most time-consuming method last in case
it turns out to be the best. Optionally, it can remove unwanted
chunks or add gAMA and sRGB chunks.
Pngnq is a tool for quantizing PNG images in RGBA format.
Pngnq is an adaptation by Stuart Coyle of Greg Roelf's pnqquant using
Anthony Dekker's neuquant algorithm.
The neuquant algorithm uses a neural network to optimise the color map
selection. This is fast and quite accurate, giving good results on many
types of images.
