clemente	0:7ad454fed160	56	* Image Format.
clemente	0:7ad454fed160	57	* About image format, I choose the way to make the library capable to read the simple RGB format.
clemente	0:7ad454fed160	58	* That's: a file with RGB bytes written. This format is very simple to obtain, using the convert.exe software.
clemente	0:7ad454fed160	59	* This program is inside the "Imagemagick" installation software. You can download the portable versio for windows
clemente	0:7ad454fed160	60	* at this link: http://www.imagemagick.org/download/binaries/ImageMagick-6.6.7-Q16-windows.zip
clemente	0:7ad454fed160	61	*
clemente	0:7ad454fed160	62	* Icone Format.
clemente	0:7ad454fed160	63	* I use some free icons from Internet. I use the bin2h utility to convert this file to .h format.
clemente	0:7ad454fed160	64	* (http://www.deadnode.org/sw/bin2h/)
clemente	0:7ad454fed160	65	*
