The dBASE GIF to PNG Converter converts files in the patented Graphic Interchange Format (GIF) to Portable Network Graphics (PNG) format, an open W3C standard. The engine of this Converter is based on a command-line shareware made by by Alexander Lehmann. The code for auto-interlace conversion was made by Greg Roelofs and production packaging by Eric S. Raymond. Actually, I just did the GUI interface in order to avoid the command-line switches.
Normally this shareware converts each file, leaving the source GIF file in place (unless the user checked the checkbox that requests the original GIF file to be deleted). The PGN created has the same prefix as the source GIF file: for example, the shareware will use Image1.GIF to created Image1.PNG. However when a multi-image GIF file named Image1.gif is converted, the shareware creates multiple PNG files, each containing one frame; their names will be Image1.png, Image1.p01, Image1.p02, etc.
The program will preserve the information contained in a GIF file as closely as possible, including GIF comment and application-data extension blocks. All graphics data (pixels, RGB color tables) will be converted without loss of information. Transparency is also preserved. There is one exception; GIF plain-text extensions are skipped.
The PNGs created
by the Converter are approximately 70% of the size of the equivalent PNGs
created by Photoshop 6.0
