Dark GDK .NET / I really need to be able to set the Bitmap Format of my GDK.Net project.

In Dark Basic Pro, there is the set bitmap format command, but I'm certain that is from the DBP update after the one GDK.Net is based on.

I can do it with "normal" C# bitmaps, using bitmap(x,y,pixelFormat), but sadly the same doesn't work for a GDK.Net bitmap.

Any ideas how I can work around this?

Thanks in advance.

It depends what you want to do with the GDK bitmap. I too would like to use [set bitmap format], but I don't think such a function exists in the library for .NET.

A assume that in some cases, creating a bitmap using the .NET framework then saving it to a png to be loaded back into the GDK via the LoadBitmap command should do the trick. But if you needed something to work more quickly, then, unless the format function was made available, memblocks bitmaps & memblock images are your only friends.

@Chris Tate:
Thanks, I didn't think of trying that that way. Basically what I want to be able to do is grab some images from the bitmap with proper alpha transparency intact.

I fear tho, that memory blocks are the way forward if I want to do this properly.

Thanks again

Cool. You probably know how to use them, but if do not; there is a guide for this on my website:

I too have found png files work best for alpha transparency.
