 |
|
Is there any solutions for the problem with image resolutions like 800x600 getting blurry when used as an ARC Sprite?
Sure one can expand the image canvas to 1024x1024, and cut the unneeded parts away in GL, but that isn't really alot of fun.

I don't think so.
That said, it should be possible to automate the process by internally allocating the power-of-two texture and placing the smaller image on it (and setting the Frame's size to the original image size). Good idea, actually - I'll put it on the roadmap.
How are your ports coming? |

Hmm, can't the GL_ARB_texture_non_power_of_two extension be used for this? (I've no idea of how to use it.)

My library porting is complete, but instead of starting to port my games over, I've begun to extend my libgmi with support for more widgets. 
I've also recently used Arc/libgmi in an AI project (tic-tac-toe) at my university.

I played with the opengl extensions, but this one isn't supported on my development machine. We could check for its availability and trigger the make-canvas-larger workaround if it's not supported.
That's what we'll do eventually. For now I'll just add code for the workaround.

Cool! If you have anything playable, remember to pass it around. |

| The updates to the texture code are now in trunk. Textures now know their image size (getSize) and the size of the containing texture (getTextureSize). |

Nice, I'll start cropping my images back to their original sizes

Sure, as soon as I have something worth playing.  |
