Is it possible to produce via Paint a file with no compression?
I'm trying to scan some files to get them to a MAC. I'm scanning
with no compression but as soon as I manipulate the file with Paint
the output gets compressed and the MAC doesn't like to see compressed
images ...
Thanks for the help !!

I assume you're converting to TIFF for the MAC. If you are, you can use DECimage services (notesfile on EDWIN::) to compress the image you get from paint, then ship it down to the MAC. You need to remember to tell the DDIF-TIFF converter to leave the image compressed, or it will decompress it for you. The calls used to compress an image are really quite simply - read the image in, get its attributes, compress the image, reset the compression attribute, and write the frame back out. Chuck | |||||

My problem is exactly the opposite !!! What I want is to have an
UNCOMPRESSED IMAGE for the MAC. The MAC utilities (according to
the MAC user !!) don't like to see compressed images. As far as I could
note the DDIF to TIFF converter does NOT decompress the image for me,
it only gives me a warning stating that the image is compressed.
I suppose the DECimage services has also routines to decompress
the images, right ?? If there is a simpler way to get PAINT to generate
uncompressed files I'd be more than happy to hear !!!

I'll try to use the IMAGE ADJUST/NOCOMPRESS command in order to
decompress an image created by Paint and then convert it to TIF
via CONVERT/DOCUMENT. Let's see what happens ...

When you convert from DDIF->TIFF, the converter allows the use of
an options file. If you specift TIFF NOCOMPRESS in the option file,
the image will be decompressed during conversion.
