This would typically be used to create graphics for display by a microprocessor, say an Arduino, on an OLED or LCD. This makes it easier to create arrays of pointers to images (very useful in various applications)Ĭommand line Python utility to output a table of hex values representing the size and data from a.

A structure ('-s') parameter has been added which uses a single 'GFXMeta' structure in the definitions of all the images.

The table name is now derived from the uppercase of the file name rather than being a command line parameter.

All of these files can be created using Adobe Photoshop (and, maybe GIMP)

bmp files are now supported (some sample files have been added to the repository). The bin2hex command line now supports multiple files for input. Added the '-v' parameter which prints the bmp2hex version.Added support for XBM output using the -x parameter.FIXED: '-d' should work as you expect whether structure is 'named' or not (i.e.Less, but with everything else that was also fixed, so much more, than it was. You might expect it to be half of what it is without '-d'. FIXED: Among other things, the number of elements in the pixel_data array was incorrect when using the '-d' option.Each 'fix' raised new issues so unless I can find a specific use case, it's not worth the effort. UNFIXED: SO, I've given up on the -d parameter for now.Some other minor changes that shouldn't affect output.Checks for non-BMP file types, bit depth > 16 and negative pixel widths and heights. Tried to provide more extensive and useful error messages for unsupported files.License: MIT Opensource License (see license.txt)
