How can I save a pixmap as a file. I'd like to save it as as JPG, TGA, etc. Is the possible with Max natively? Has anyone ported FreeImage yet ?

Thanks

The PNG Loader module has a SavePixmapPng function, I don't know what other formats have a save yet.

Uhm... it says "Identifier not found" when trying to save a pixmap using SavePixmapPNG.

Identifier not found suggests you are using a non-existant variable.

It says: Identifier 'SavePixmapPNG' not found.
Try it yourself.
LoadPixmap doesn't work, too.

This works for me:

SetGraphicsDriver(GLMax2DDriver()) 
Graphics 640,480,0,0

Global myPixmap : TPixmap

While Not KeyDown(1)
Cls
DrawRect(10,10,100,100)

Flip

If KeyHit(KEY_P) Then myPixmap = GrabPixmap(0,0,640,480)
If KeyHit(KEY_S) Then SavePixmapPNG(myPixmap, "c:\myimage.png")

Wend

End

It's a bit old but you might find it interresting to look at :
