示例1: Main
// Main draws "Hello World" and returns the filename. This should only be
// used during testing.
func Main(gc draw2d.GraphicContext, ext string) (string, error) {
// Draw hello world
Draw(gc, fmt.Sprintf("Hello World %d dpi", gc.GetDPI()))
// Return the output filename
return samples.Output("helloworld", ext), nil
}示例2: UseImageWithContext
// UseImageWithContext specifies both an image
// and a graphic context to create the canvas from.
// The minimum point of the given image
// should probably be 0,0.
func UseImageWithContext(img draw.Image, gc draw2d.GraphicContext) option {
return func(c *Canvas) uint32 {
c.img = img
c.gc = gc
c.dpi = gc.GetDPI()
return setsDPI | setsSize
}
