Subject: Re: Convert a 16bit TIFF to a 4bit TIFF
In reply to: Heiko 's message, "Convert a 16bit TIFF to a 4bit TIFF" on 06:25:53 10/08/01 Mon

Hi Heiko,

Try using,

EnMisc.ifColor16 instead of just ifColor16. The TImageFormat type is from EnMisc. This will avoid confusion if you have another unit that may have ifTrueColor.

Best regards,
