The manual has some great information on file formats, preceded by these two lines:

Quote:

---

Supported image formats are PCX, BMP, TGA, DDS, PNG, JPG, and WAD. All formats have their specific advantages and disadvantages.

However, the advantage/disadvantage of PNG is not described in the following paragraphs. Will I have less video memory consumption if I use PNGs instead of JPGs?

PNG has the same quality and video memory consumption as TGA. But unlike TGA it's supported for bitmaps only, not for level textures.

I did not test, but can acknex handle indexed png, without using the same palette for all
pngs. (transorming the png indexed input to true color bitmaps when loading)
This would substancially decrease the diskspace, when using png for big bitmaps, that dont require many colors.

why not? i don't think conitec uses a proprietary png file filter.

I don't know if indexed PNG is supported, but indexed images in a game in 2008 would be hardly appreciated. For saving space, use DDS.

maybe here is not the right place to ask,
but ill ask anyway
I never worked with DDS images, what are they pros/cons?

thanks

hmm... english? lol

I see but still i dont know the pratical pros and cons when working with them in 3dgs..
why should i use them? or is it a waste of memory using TGA when I can use DDS?
things like that..
thanks
