Some Graphical Issues with Sprite Sheets

Solar2D General Questions/Discussion
#1

I seem to have a problem with the quality of the graphics on the device and the simulator when coming from sprite sheets.
While talking this over with Andreas from Texture Packer he thinks that there might be some subpixelrendering in Corona that might be making the graphics blurry.

The second issue is when I scale sprites. It seems that Corona doesn’t take in to account padding in the scaling and this is cutting off some of the graphics when they are scaled down. Just a hypothesis.

Is anyone else seeing these issues?

Thanks

Make sure frames in the sprite sheet are even numbers. Odd numbers in the dimensions cause blurriness. To test this try setting the sprite at a .5 x or y value. [import]uid: 11024 topic_id: 3788 reply_id: 11526[/import]

I am still having issues with blurry graphics. It’s very strange. Can someone at Ansca help me with this? I can send files. It just seems very random and only happening on the simulator and device. The graphics in TexturePacker are fine then some of them become blurry in Corona. [import]uid: 8192 topic_id: 3788 reply_id: 13055[/import]

@finnk. You were correct the pictures going in from Fireworks where odd px value. Unfortunately Fireworks trimming function is sort of buggy and doesn’t trim properly. Unfortunately for now I have to manually change the value in the lua file created by texture packer. I am working with Andreas, creator of texture Packer to see if he can implement an automated solution. [import]uid: 8192 topic_id: 3788 reply_id: 13108[/import]
