Hi.

Why can't I read TIFFs compressed by JPEG using GDI+ Image class? I always
get out of memory exception.

Thanx.
 
Hi,

I don't know about JPEG compression in TIFF standard.
TIFF supports only LZW algorithm.

It looks like "your compressed TIFF" image is out of GDI+
possibilities.

Cheers!

Hi, Marcin!

JPEG compression is described in TIFF 6.0 specification. By the way GDI+
reads some of tiffs compressed by JPEG, i suppose it depends on color depth
or something else.

Hi again,

I'm affraid that my knowledge about TIFF standard is
"little" out of date ;)

Only that i can say that JPEG compression works with
24bpp or 8bpp (in grayscale) - usually ;)

Cheers!

Marcin
