Automatic atlas dimension

[rtalon83]

Current Behavior

You must set the max dimension in your expected atlas (1024x1024, 2048x1024, etc).

Desired Behaviour

I want to a only atlas without packs. The max dimension of this map will be automatic.

Hello. You can set dimension to the large values (10240x10240 for example) and do not check "Fixed size". Texture size will be selected automatically.

My problem:

For example, I have 50 images where I know that their can fit in 2048x2048. If I set 'fixed size: false' and dimension 4096x4096 the result, more or less, is 1022x3000, sometimes 900x4025, random non-cuadratic values. My question is: Is possible try to tell algoritm that make cuadratic atlas? Do you know?

[odrick]

I understood. We need an appropriate algorithm. Now used MaxRectsBin. Perhaps you know the algorithm that is best for your task? I will try https://www.npmjs.com/package/maxrects-packer in few days for example.

This can be especially useful for WebGL games where the GPU will benefit from spritesheets close to power-of-2 sizes.

Fantastic! I will try to investigate too Thanks!

I'm watching https://github.com/soimy/maxrects-packer and I think that we have a little problem. The option rotate I can't find it.

Yes, it's true. But this is a realy small problem :) Please, check MaxRectsPacker algorithm here: http://free-tex-packer.com/test/ . Set Packer to MaxRectsPacker and try different methods.

Yes!! Thats what I hope happened!! Amazing!!

All correct!

Excellent :) I will prepare a new release of the application and console utilities by the end of the day.

Perfect! Is a good feature for your app. Congrat! You can close this issue. Thanks!
