[Privoxy-users] External filter examples

Hello,

I've been experimenting with the external-filter functionality, and have
been trying to get image manipulation working. I have been basing my
efforts on the examples at the bottom of
https://www.privoxy.org/user-manual/filter-file.html

However, whilst I can get external-filters for text content to work, I
cannot for images. The documentation seems contradictory - it says at the
top of that section that it only applies to text, but later it gives an
example using the "convert" utility.

After digging through the source I found the text limitation was indeed
correct (checks for CT_TEXT); modifying this to allow images as well
enabled the examples to work.

I just wanted to check that this was really necessary and I haven't missed
some option somewhere that would enable the examples to work properly?

Thanks,

Sam
