Cant find any info about what kind of image file formats is supported in Help files that comes with this app.

Can anyone list full info about this subject? (maybe there is restriction like 16 bit only etc)

I think it is best to get used to using PNG with alpha channel. It's the only way to have irregular shaped sprites and images and varying level of transparency.

i kinda wonder about using png on sprite atlas textures.

does anyone notice a blured effect with a sprite scaled bigger?
i was wondering if there is a setting to stop that from happening.

i see it less if its a bmp file on my windows pc...maybe this is an odd case?

edit: here are the original atlas textures...1 bmp and the other png

here is a screen shot showing my problem between the 2 formats on windows.... bmp seems to look much better... why is this?

i wish it was more sharp like the originals posted 1 post up

edit:this may be platform specific... cause it actually looks good on my blackberry to load in the png.... just not on my windows pc.

Have you tried using:
SetImageMinFilter(imageID, 0)
SetImageMagFilter(imageID, 0)

Looks like you might have lost your transparency, how are you loading the image?

just with
imageid=4
loadimage(imageid,file$,1)

im also setting an atlas texture for my sprite

SetImageMinFilter(imageid, 0)
SetImageMagFilter(imageid, 0)
setspriteimage(1,imageid)
setspritescale(1,2,2)
setspriteanimation(1,32,32,16)
setspriteuvborder(1,0.5)
setspritedepth(1,10)

its strange cause the transparency is still with the sprite...its just blurred something bad. Mostly visible when scaled bigger.

@bax.. thanks for those commands but looks like i still have a weird smearing effect with my sprite. It just looks like a sharp blurr mixed together.. see image.

oddly this is just on windows...

[quote]loadimage(imageid,file$,1)[quote]

Will overwrite the alpha channel with the black pixels used for transparency instead, set the last parameter to 0 to use the PNG transparency.
