C++ (Cpp) tglColor4f Examples

Example #1

File: gfx_tinygl.cpp Project: eriktorbjorn/residualvm

void TinyGLRenderer::drawRect2D(const Common::Rect &rect, uint32 color) {
	uint8 a, r, g, b;
	Graphics::colorToARGB< Graphics::ColorMasks<8888> >(color, a, r, g, b);

	tglDisable(TGL_TEXTURE_2D);
	tglColor4f(r / 255.0, g / 255.0, b / 255.0, a / 255.0);

	if (a != 255) {
		tglEnable(TGL_BLEND);
		tglBlendFunc(TGL_SRC_ALPHA, TGL_ONE_MINUS_SRC_ALPHA);
	}

	for (int x = rect.left; x < rect.right; x++) {
		for (int y = rect.top; y < rect.bottom; y++) {
			_fb->writePixel(y * kOriginalWidth + x, a, r, g, b);
		}
	}

	tglDisable(TGL_BLEND);
}
