Tying to convert a 8bpp to 4 bpp Posted by \ at 8/28/2007 8:44:34 AM I'm about ready to give up.
Been trying to convert a 8bpp to 4 bpp but haven't found a way.
I can us Quantizer to generate a 16 color palette but that changes the pixel
format to 8 bpp.
I can convert to 4 bpp using GetDIBits but that converts to the standard VGA
palette.
So I can com...more >>

Can't draw? Try going native? Yeah right. Posted by Norman Diamond at 8/27/2007 12:00:00 AM How many invalid parameters are there in the following method call?

invalid parameter in the above call. And the invalid argument exception was
unhandled, well no kidding about t...more >>
Can an indexed BMP file be saved as 4bpp? Posted by \ at 8/26/2007 9:58:11 AM I'd like to be sure I completely understand: There is no way, using Dotnet
and/or some free software, to save an indexed GIF file as anything but 8bpp.
Right?
What about other indexed files like BMP. Same problem?
What files have that property.
Knowing this before I work with them...more >>

OutOfMemory is intermittent, maybe here's why Posted by Norman Diamond at 8/23/2007 12:00:00 AM After a call to Graphics.DrawImage, an OutOfMemory error might occur. The
probability of an error has some correlation with the size of the image but
is not reliable. Even with an image of a few hundred megabytes, sometimes
the error occurs and sometimes not. Some random postings on the web...more >>
