Dfilter is a program that will correct incompatibilities in
Photon Paint and Pixmate images in Directors dated before
|c73/22/88|c3|-. To determine the date of your Director, run it and
notice the date output after the version number.|r1
|e
If your Director is earlier than |c73/22/88|c3|-, you may want to consider
sending in for the upgrade. Our upgrade policy works like this:|r1
|+21. Send in your master Director disk. This is what we use for|r1
|+6proof of purchase. The registration card is for our mailing|r1
|+6list and is not required for the update.|r1
|+22. Include $10 ($15 in U.S. funds outside US).|r1
|+23. That's it. We'll send you the latest version. Turn around is 2|r1
|+6to 3 weeks.
|e
In the meantime, to use DFilter from the |c7CLI|c3|-, type:|r1
|+8|c71> dfilter filename|c3|r1
Where |c7"filename"|c3 is the file name of the picture file to be modified.
If the file is on another disk or another directory you will have to
specify the complete pathname for example:|r1
|+8|c71> dfilter df1:pictures/image1|c3|r1
|e
Photon Paint inserts a proprietary |c7IFF|c3 chunk as the first chunk
of the file. The Director originally assumed that the first chunk
will be a |c7BMHD|c3|-, and treats any file that doesn't start with such a
chunk as bad. Dfilter will move the |c7BMHD|c3 chunk in the |c7IFF|c3
file up front so the files will work correctly.|r1
The original Pixmate saved the viewmodes in the |c7CAMG|c3 chunk, with the
|c7SPRITES|c3 and/or |c7VP_HIDE|c3 bits on inadvertently, which will cause
GURU's in the Director. Dfilter will turn off these bits so the files will
work correctly.
|e
Dfilter works "in place", that is, it modifies the file you
specify without creating a second file. If you feel uncomfortable
about such a program modifying your only copy of a given image
file, copy the image file to |c7RAM|c3 first, run dfilter, and check
with a display program before replacing your only copy of the
image.
