I've used for the test below Paint Shop Pro 5.03 from Jasc.
I've written a small application that convert between .BMP and .TIF, using LibTif.
Paint Shop Pro 6.00 beta 19990810.13 don't crash, but say "this is not a valid TIFF file"
Somes other application, including Word 2000 or Acrobat 4.0 import correcly this file
You can download tiffdemo.zip.
There is a Visual C++ 6.0 project, the executable and the image file.
Release\TiffDemo.exe is the compiled Win32 console apps
image\tstimage.bmp is the original file
image\tstimage.tif is the result file, that crash Paint Shop Pro 5.0
You can also just download the Tiff image : tiffdemo.tif
If you run
TiffDemo tstimage.bmp tiff 1
You'll have an uncompressed tstimage.tif (776 390 bytes) that don't crash PSP
If you run
TiffDemo tstimage.bmp tiff 50
You'll have an compressed LZW without predictor tstimage.tif (165 910 bytes) that don't crash PSP
If you run
TiffDemo tstimage.bmp tiff 5
or
TiffDemo tstimage.bmp tiff
You'll have an compressed LZW without predictor tstimage.tif (185 424 bytes) that DO CRASH PSP
When I save this image in TIFF LZW compressed with Paint Shop Pro, I've 124 032 bytes file
