Hello people

does anyone know if gd2 supports the BMP windows format?
I am trying to find functions similar to:
* imagepng
* imagecreatefrompng

for manipulation of BMP files

regards

As far as I can tell from http://php.net/gd there is no support for image creation of BMP. There is however wbmp (wireless bitamps) functions that are used for black/white low rescource handhelds and such.

Actually speaking gd developers could have supported bmp formats but I guess they targeted for web-specific images mainly ? Outputting BMP is not that tough to implement - they are just uncompressed pixels with the colour code at each location. Theres just 2 headers which you'll need to read properly.
I dont know wheres the original format location - but heres where you can start : http://www.dcs.ed.ac.uk/home/mxr/gfx/2d/BMP.txt
Search wotsit for any format
