Re: problem with delegates.xml
I know nothing about delegates, but dcraw 8.86 has option -c to write to stdout, so can you > that to %o?

Can you post a link to the xcf file so we can try it?

Re: Dealing with alpha layers in TIFF->JPEG conversions
Thanks, magick.
There is also the question of why
convert mask.tif mask.jpg
convert mask.tif -resize 100x100 mask.jpg
do two different things with alpha.

Re: How to save the DIFFERENCES between two images ?
I'm guessing, but see command-line-options, for -transparent-color:How does this know that we want black as transparent?
"The default transparent color is #00000000, which is fully transparent black."

Re: Chaining Successful Commands
Ah, yes, of course. "\" is bash, not PHP. And I'm not sure if you need to escape the brackets. Splitting the lines in PHP would be something like: shell_exec( <<<theEnd /usr/bin/composite -gravity center /full/path/to/overlay.png /full/path/to/image.png miff:- | /usr/bin/convert - -resize ...

Re: -bash: /usr/bin/convert: No such file or directory error
If I understand you correctly:
1. Executing "$ convert" runs /usr/bin/convert.
2. "which convert" shows /usr/local/bin/convert.
If that's true, something is badly wrong (with your Unix, not Imagemagick).

Re: Chaining Successful Commands
I would do the obvious things, like ensuring that some IM command works, then splitting this one into two so it doesn't use pipes, and so on.

Re: Auto-detect optimal image output format, How to
You'll have to do trials, trading off download size, visual appearance and programming complexity.
In my experience, most scanned pages compress best in jpg, even the most graphic kinds. (But your scans may be different.)

Re: Transparent color: black
Editable only as pixels. ImageMagick is a raster processor -- it deals with pixels.

Re: Transparent color: black
"Flatten" is what does the work. The "-background" just declares the colour that will be used by any operation that needs a background.

Re: Chaining Successful Commands
"miff:" is a file format, not a command. The "-" means send it to stdout. You need a corresponding "-" in the next convert to read from stdin.
convert - -resize 128x128! \
etc
convert - -resize 128x128! \
etc

Re: PNG2TIFF width transparent background
What version of IM are you using?
When I use
convert test.png test.tif
(version 6.4.5) my result looks like what you want.

"identify verbose" tells me the image has a conventional alpha channel. If you effectively want to place this image in front of a white background, so the white shows through the transparent areas, try: convert newsletter.png -background white -flatten newsWhite.png [Edited: added "-&...

Re: Transparent color: black
Is this for 256-pallette Gif?
The "-transparent-color" option is probably what you need.
