create Image from RGBA buffer

[Jeevhi]

Is there a way to create image from RGBA buffer and specifying parameters width, height, depth etc.

Currently I have modified gdImageCreateFromBmpPtr and gdImageCreateFromBmpCtx functions to take bmp_info_t as parameter. However would be nice if you can add a function, and export it.

Or am I overlooking something ?

No, because that specification isn't specfic enough. Is that really an RGBA buffer, or rather an ARGB buffer (or some other order)? What are the supported ranges for the color components (8bit for all of them; 16bit; or like libgd, i.e. 8bit for RGB and 7bit for A)? Is the layout row-first or column-first? Is there some specific padding? etc.

You can, however, write your own routine which creates a GdImage manually.

to put into concrete terms, if we started down the path of providing pixel converters, how many would we want to support? i don't know if there's a list somewhere that ranks "common" ones that we could use to decide when to stop.

ffmpeg supports a lot which leads to a ton of boilerplate.

at the very least, we could have an example program to convert RGBA of some bit depth and just point people to that to write their own.
