I'll take a look at it tomorrow. Meanwhile, you could use the ScriptPanel and simple draw the image there (the ScriptPanel is working correctly, I am using it for another iPad project).
const var Panel = Content.addPanel("Panel", 0, 0); // [JSON Panel] Content.setPropertiesFromJSON("Panel", { "width": 1024, "height": 768 }); // [/JSON Panel] // Load the retina image with double resolution Panel.loadImage("{PROJECT_FOLDER}bg.png", "bg"); Panel.setPaintRoutine(function(g) { // name, x, y, w, h, xOffset, yOffset g.drawImage("bg", [0, 0, this.getWidth(), this.getHeight()], 0, 0); });
