Subject: Re: Creating a TIFF file from a TBitmap
In reply to: Michel 's message, "Re: Creating a TIFF file from a TBitmap" on 07:13:25 05/09/00 Tue

Hi, everything works well now. Thanks! I have one more question, though. I have a scanning application that saves images in TIFF CCIT Group4 Compression. They are monochrome 200 dpi. I can greate a TTiffGraphic with the same dimensions but the number of "Rows per Strip" does not match. I need these images to be as similar as possible because I have to write a tiff2pcl program so they will print from Unix.

Also the Tiff Directory is reported at offset 0x1c0 in the image created by envision but at 0x8 with the Kofax scanning software.

Are these things changeable with the source code?

Thanks in advance.
