LodePNG

LodePNG is a PNG image decoder and encoder, all in one, no dependency or linkage to zlib or libpng required. It's made for C (ISO C90), and has a C++ wrapper with a more convenient interface on top. It has all the code for zlib compression/decompression, PNG filtering and chunk handling, and ... [More] color type conversions, in 1 single .c or .cpp file of only a few thousands of lines. It supports PNGs with all color type, interlace type and compression type combinations and supports the alpha channel, in both the encoder and decoder. [Less]

meh

meh (correctly pronounced with indifference) is a small, simple, super fast image viewer using raw XLib. It is similar to feh, but faster and simpler. meh can use ImageMagick's convert executable, if it is installed, to view almost 200 file formats, including SVG and PDF, though it is slower ... [More] for these formats. Built in (fast) formats are JPEG, PNG, GIF, BMP, and netpbm. [Less]

imageguide

Most images online which use limited colors or are charts, graphs, or similar should be saved using the PNG format. PNG makes these images not only look much better to the viewer, but it generally makes them smaller and quicker to download as well. Other images, such as photographs taken with a ... [More] camera, are almost always best saved in JPEG format. Unfortunately, most internet users do not know how image compression works and have no idea which format to save any particular image in. ImageGuide helps you figure out which format to save an image in. It is designed to be extremely easy to use and supports all major platforms. ImageGuide saves your image in both formats, using roughly the same amount of disk space, and allows you to see which looks better. If you cannot tell, it gives you the option of recommending a format, and can even save the file for you. While ImageGuide does have the option of saving images, it is usually best to use a dedicated art program such as Adobe Photoshop or The GIMP. These programs generally have more refined image saving features and may be able to make your image smaller and better looking than ImageGuide. ImageGuide should be used primarily for deciding which format to use. Because ImageGuide uses the colors recommended by your computer (the "system palette"), PNG images may not look as good as they could when using a program with smarter color tools. I hope to implement a color chooser (using the Median Cut or similar algorithm) at some future date. [Less]

lib-pdf

LibPdfThis library converts converts PDF file to an image. Supported image formats are PNG and BMP, but you can easily add more. This library uses poppler-qt4 library with QT frontend. Basically it's managed C++ wrapper over limited subpart of poppler-qt4 functionality. Usage example: using ... [More] (FileStream file = File.OpenRead(@"..\path\to\pdf\file.pdf")) // in file { var bytes = new byte[file.Length]; file.Read(bytes, 0, bytes.Length); using (var pdf = new LibPdf(bytes)) { byte[] pngBytes = pdf.GetImage(0,ImageType.PNG); // image type using (var outFile = File.Create(@"..\path\to\pdf\file.png")) // out file { outFile.Write(pngBytes, 0, pngBytes.Length); } } } Installation and configuration [Less]

img2gpx

This program creates a GPX file (http://www.topographix.com/GPX/1) holding the points as read from a png image (usually a scan of a map). The principal aim of the program is to allow the user to pinpoint waypoints on a map (e.g. very detailed hiking maps) and to transfer these waypoints easily on a ... [More] GPS receiver. Read the Manual to learn how to use it. There is no compiled download (since the program is still under development), but the source is in the SVN-repository and the basic functionality is available.
