Hi:

I am using STM3221G-EVAL board, with the demosntration builder firmware.

There are multiple icons on the initial screen, and I would like to replace one of those, with one of my own icons. I have tried emWin BmpCvt and LCD Image Converter to get the C code corresponding to the image, without success.

My initial image is a bmp 360x369 pixels, that I have reduced to several sizes but nothing seems to work. The icon is showing at the screen but just streaks.

What is the procedure I have to follow to do this?

Thanks,

#an3128 #emwin #icon #bmpcvt #lcd-image #rgb565 #rgb565 #image-converter

''Some of the example in ST's code actually have a ''BM''  0x42,0x4D header, whilst others don't''

Yes - the above-mentioned Image Converter from the ST Resource Editor has the option for with/without header.

''Well I'm sure they just did what was quick and convenient''

Indeed.

''At some level people are expected to have some conceptual understanding about what they are working with, and how to identify the formats being used''

I'm talking about the 'C' arrays provided as source in the demo application.

It doesn't take much to describe what they've implemented, and say ''Utilty xyz can be used to convert from whatever image file types''

Or, for that matter, have the tool fingerprint the comments saying what source file was used, and the command with command line options.

Indeed!
