How to make a custom progress bar with image?

dxDrawImageSection can be used to draw part of the image. For a 0-100% progress bar, to show a certain percent, math.floor or math.ceil ( ( % to show * image total width ) \ 100 ). Then you use that as the width amount for your dxDrawImageSection as the section you want to draw.

If you're looking for some more advanced technique then you can use a shader. So that you can create a render target and draw on it with dxDrawRectangle or any other dx function and then apply a shader with a masking texture to it. That's how author of the GTA IV HUD resource achieved the radar drawing and health bar around the radar.
