Use cairo instead of Skia if you can avoid it in gtk code.

changed, or is the situation different on linux for some reason?

To answer the technical (non-political) part of this question.
Create a SkBitmap which backs to some pixels. Create a SkCanvas on
top of it. Call drawPaint or more directly drawColor.

Thanks for all the answers, especially the first one from erg. I'm going to
use Skia, because another method (SetBackground in RWHV) requires that.

Without any testing at all, it would look a little like
SkBitmap bitmap;
bitmap.setConfig(SkBitmap::kARGB__Config,
See what I do in GtkThemeProvider::LoadThemeBitmap:
SkBitmap* bitmap = new SkBitmap;
bitmap-setConfig(SkBitmap::kARGB__Config,
kToolbarImageWidth, kToolbarImageHeight);
bitmap-allocPixels();
bitmap-eraseRGB(color-red 8, color-green 8, color-blue 8);

There's an example of how to do this with skia in
src/app/resource_bundle.cc around line 146. That said, you should use
cairo to paint in GTK.

This code is incorrect, you should divide by 257, not 256. See the
GDK_COLOR_RGB macro.
That's not true. GDK_COLOR_RGB multiplies by 257 (= 0x10001) to
distribute the bits evenly (
http://www.mindcontrol.org/~hplus/graphics/expand-bits.html ). To get
back, you can just shift (or, formulated
Yes, this can be reformulated easier as
i * 257 = i * 256 + i
and i / 256 will always be zero for i 256. Anyway, I suppose it
doesn't matter. The question is what to do for mapping 16-bit back to
8-bit, when it wasn't necessarily originally produced from 8-bit. I
suppose that dividing by
