Re: What does turning alpha on and then off again do?

Sorry, I wasn't clear: most of my textures do have alpha. The one I posted here is actually an exception, I'd say at least 95% of all my textures do have alpha. Lots of character sprites and such. When alpha is present, the subtle white halo is a problem, suggesting I should use it without the alpha ...

Re: What does turning alpha on and then off again do?

Quite surprising this was a bug, I expected I was just doing something wrong... ;) Is there any reason I should leave the alpha off/on in? Subtle white lines around objects is definitely a problem (we have tons of alpha-objects in Awesomenauts), and I don't see any benefit to it. Can you think of ...

Code: Select all

convert.exe input.tga -resize 1024x512! output.tga

convert.exe input.tga -alpha off -resize 1024x512! -alpha on output.tga

Re: What does turning alpha on and then off again do?

Thanks for the reply! :) I thought "-alpha off" was a parameter, but it is a command, isn't? So do I understand it correctly that if it says "-alpha off -resize 25%% -alpha on", this actually means three commands in a row: it turns the alpha off, then it resizes, and then it turns alpha back on. Do ...

What does turning alpha on and then off again do?

We use ImageMagick to rescale images to a smaller size for our automated build pipeline. Now a former colleague (who is not with the company anymore and thus cannot explain this) changed how ImageMagick is called. It was for example this: convert.exe input.tga -resize 128x128! output.tga He added ...
