hmmm 3 X 3? ... too small. Does it mean that any starting image must
have this rect?
3X3, of course, means the size of the matrix filter, you can use Chipp's
DLL for any image size and different rects (as far as my experiments
went). My own scripted filters are adapted to an image size of 640X480,
but that could be easily changed; however, the larger the image, the
more processing time is needed - execution time for most of the no-dll
640X480 filters is between 1 and 2 seconds. When the DLLs are used, the
results are instantaneous.
As I have already mentioned as a request, a nice add-on for Revolution
would be a DLL (and the equivalent for MacOS) for a filter size of 5X5
or even better 7X7. Photoshop CS (1) allows for the setting-up of
user-defined filters with a 5X5 matrix. PaintShop Pro offers a 7X7 matrix.
I am not familiar with creating DLLs, but my guess is that it could not
be too difficult to extend the functionality of Chipp's and Derek Bump's
3X3-matrix DLL to cover a 7X7 filter matrix.
One thing is missing in the 3X3 Dlls, which include the "division"
factor - "scale" in Chipp's and Derek's stacks, namely what is called
"shift" in Photoshop and "bias" in PaintShop Pro. This is a color value
to be added to the equation important for instance for creating "relief"
(and other) effects. I tried to add such a "bias" to Chipp's scripted
(without DLL) solution, but did not get the same results as with
PaintShop Pro. Otherwise the PaintShopPro sample filters, so far as they
fit into a 3X3 matrix, yield the same results in my "ImageFilterDemo"
that contains a modified version of Chipp's stack.
Especially PaintShop Pro 8 contains about 15 3X3 usable matrix filters,
versions 7 and 10 only about 5, that could be used in our sample stacks.
I will add some of these filters to a new release of my ImageFilterDemo.
I might also give it a try - in case I find time - to extend Chipp's
no-dll version to encompass a 4X4 matrix.

Keep us all posted. My needs are pretty much always the same -- and
this would apply to most users needing to get from raw camera to web
quickly, assuming they don't have time to tweak levels or fix red-
eye -- or those who have no clue what that stuff even means.
one pass: raw Digital camera image.jpg
1) rotate
2) downsize
3) autolevels
4) unsharp mask (I will try sharpening, but for sure it's not as good
for edges)
5) save jpg "optimize"
Option to turn off 4) 5) above where the image has already been
through one in interpolation and more filters will simply degrade.

The needs are certainly different for all users, but in any case it
would be a valuable enhancement to Revolution to have improved
image-processing capabilities, both with extended filter matrices and
possibly with a DLL that would open the door to work with
Photoshop-compatible plugin-filters.
Such enhancements would certainly attract new users and encourage
present Revolution users to experiment with image processing.
