Example #1

wxBitmap sim_area_widget::convert_to_bitmap(const image& img)
{
	std::vector<unsigned char> rgb;
	rgb.reserve(img.size_x() * img.size_y() * 3);
	std::vector<unsigned char> alpha;
	alpha.reserve(img.size_x() * img.size_y());

	for (int i = 0; i < img.size_x() * img.size_y(); ++i)
	{
		rgb.push_back(img.data()[i * 4]);
		rgb.push_back(img.data()[i * 4 + 1]);
		rgb.push_back(img.data()[i * 4 + 2]);
		alpha.push_back(img.data()[i * 4 + 3]);
	}
	
	return wxBitmap
