hmmm. Altuit, I could be getting old but I'm not seeing any links to
Chipps "freeware" from the top level of Altuit's site...
and Derek Bump's adaptation of this stack and DLL that corrects the
yellow color shift (<www.dreamscapesoftware.com/products/>). Both
stacks contain 9 filters based on a 3X3 filter matrix, among them
sharpen, blur, emboss etc., but not unsharp. The filter matrix can
be used to experiment with own matrix settings.
hmmm 3 X 3? ... too small. Does it mean that any starting image must
have this rect?
I had embedded Chipp Walters version into my
"ImageFilterDemo" (<www.sanke.org/Software/ImageFilterDemo.zip>)
and got responses from Chipp and Derek. One interesting thing is
that Chipp demonstrated that it is possible to script filters (3X3
matrix) completely in Revolution without using a DLL, however the
execution of such a script is much slower than with the help of DLL.
I am experimenting myself with scripted filters, some of which are
contained in the ImageFilterDemo, about a hundred or so will be
available shortly in my "Imagedata Toolkit".
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.
