I am wondering if anyone can suggest which file types are best for using when texturing in DB/DBPRO, I am asking as I realise BMP are good quality but large in size, I was wondering what other file types, if any?, are better or the same quality as .BMP but have a much smaller file size for the same picture/texture held on it?.

Many thanks

Personally I always use PNG files. They're a non-lossy format (unlike JPEG), smaller than BMP by far and support alpha-channels. Lovely.

Cheers,

Thanks Rich, I appreciate the help here as I am not an artist by any means, I tried the .PNG format quickly and it does the job REALLY well, 5mb+ to 180k.. and no loss as you say in quality! There's alot to be said for using the correct file formats..

Thanks again

And with .PNG graphics you'll never have Unisys claiming you owe them money for using their algorithm! (a potential problem with .GIFs)

I thought GIFs just used RLE?

some do... so many brandings of it, its hard to tell really - and as most Operating system have builtin things to distinghuish between all of them blah blah.

personally i'd say fudge it and create me own dang format ... use a TGA to map out everything in my 3d package and then export 2 bitmaps, one 24bit colour the other a 256 greyscale alpha ... import both into db
export as my image type which is constructed into a 32bit memblock on loading

you have 4 byte positions per pixel
RED GREEN BLUE ALPHA ... 0 - 255 values

no problem importing your own format as long as you understand the codec you make for it (^_^)
