Images from MTGA exporting at a square resolution instead of proper rectangular resolution #327

Closed daftinquisitor closed 5 years ago

daftinquisitor commented 5 years ago

I'm not sure if this is just an issue with Magic The Gathering Arena, but whenever I attempt to export images from the game, it exports them as perfectly square images every single time, despite the fact that most of the images are meant to be in a rectangular format. Is there anything that can be done or looked into?

I can provide instances of the original data files, as well as the exported images, if needed.

Yes, upload original data files and tell which images should not be squared

There are five images in this file when exported, 406403_AIF.png through 406407_AIF.png, and each one of them comes out with a resolution of 512x512. The images should be closer to 718x512 (though I don't know the exact resolution). This same process happens with every image I try to export from the game files, even if the base resolution is different -- e.x., some files get put out at 1024x1024 instead, but they're still square instead of rectangular. g18_cardart_17a1b2beba397648819aa2b533bcf32e.zip

I think developers stretch those images at runtime. Some compressions supports only square images (eg pvrtc on iOS) so that is the way they save storage and memory

I wouldn't think this particular developer would be worried about something like that, but I could be wrong. Thanks for at least looking into it.

If they are going to release it on mobile they have to worry about it.
