How to load a SVG image and render it scaled at high quality?

[Phillipus]

Edit - I now realise that I'm seeing this problem on Mac and Linux but not Windows. I compared the results of loading an SVG file using the following two methods and there is a difference in quality on Windows and Mac/Linux when scaled. On Windows the SVG is crisp, but is blurry on Mac/Linux.

It seems the only way to get a high quality SVG scaled image is to load it from file using a ImageFileNameProvider passed to the Image constructor.

Image image1 = new Image(display, getClass().getResourceAsStream(imgPath));
Image image2 = new Image(display, imgPath);

GC gc = // GC passed from caller 
gc.drawImage(image1, 0, 0, 300, 300);       // scale the image larger
gc.drawImage(image2, 0, 400, 300, 300);   // scale the image larger

I'll open an issue soon.

If I am not mistaken, this was turned into an actual issue and should be further discussed there?

• Non-blurred SVG image scaling with GC.drawImage(Image image, int destX, int destY, int destWidth, int destHeight) only works on Windows unless an ImageFileNameProvider is used #2917

Yes, that's right. This question was the beginning of my journey where I finally realised the problems were coming from differing implementations in GC :-)

So I'll close this one.
