C++ (Cpp) nvgCreate Examples

Example #1

File: main.c Project: yui0/catgl

// 表示の初期化
void caInit(int w, int h)
{
	width = w;
	height = h;
	pixelRatio = (float)width / (float)height;

	vg = nvgCreate(NVG_ANTIALIAS | NVG_STENCIL_STROKES);

	if (loadDemoData(vg, &data) == -1) return;
}

Example #2

File: main.c Project: yui0/catgl

// 表示の初期化
void caInit(int w, int h)
{
	width = w;
	height = h;

	// Calculate pixel ration for hi-dpi devices.
	pixelRatio = (float)width / (float)height;

	vg = nvgCreate(NVG_ANTIALIAS);

	//nvgCreateFont(vg, "sans-bold", CATGL_ASSETS("Roboto-Bold.ttf"));
	nvgCreateFontMem(vg, "sans-bold", mplus1pregular, sizeof(mplus1pregular), 0);
	nvgFontFace(vg, "sans-bold");
}
