Is there a library to show a pciture on my RGB led Matrix Display?

Or a extern tool that can convert a image to 64x32 pixel image with coordinates?

I buyed a 64x32 pixels RGB Led Matrix Display that i have a Particle Photon connected to and now i with the RGBmatrixPanel library i have show text and maked it show the time.

But have anyeone done something like taken a image convert it into the coordinates with colors you need and put the code in the photon to show it.

I have found some library fror Raspbbery pi todo it but not for arduino…

And can someone explain how to convert ex HEX color or RGB color to the matrix.setTextColor(matrix.Color333(1,1,7) funCtion ?

For color setting - it seems it has also 8-bit color method. So

matrix.Color888(r, g, b);

Where r, g and b are values from 0 to 255. If you have HTML hex color like #FFCC00, just split it to pairs: FF, CC and 00. And use with function above:

matrix.Color888(0xFF, 0xCC, 0x00);

Basically add 0x in front of whatever pair you have. This prefix means hexadecimal number, so you can use numbers as they are.

This may help you. You need 24 bit color data output (3 x 8 bit). But have no experience with it, so you will need to experiment.
