I presume all the patches are for 6.7.6.2 as my original post still fails for 6.7.6.1.

So color is not yet working right in pango:

P.S. Also there are no docs for pango on the options page at http://www.imagemagick.org/script/comma ... ptions.php

That is coming, according to what Cristy has mentioned to me.

There won't be either. pango: is a coder (image generator), not an operation or setting.
When things have settled I'll add it to the Text to Image Handling page of IM Examples.

Note that few of the things I detail about for label: or caption: are in Im reference pages either!
Really the 'formats' page should use a expansion so extra notes about specific coders are explained, perhaps as a multi-column span line below the entry rather than in the limited column space to the right.

Yes, you are right. I had forgotten about that.

But I see now that pango: is explained at http://www.imagemagick.org/script/formats.php#pseudo

But I see that show: is not listed there.

Their are a few documentation errors. "preview:" is not really used. "clipboard:" is shown as a file-format (as well as correctly as a psuedo-format. and a few other things.

However "show:" is not a coder, but a "spawning delegate" for the "display" program (spawning = backgrounding)

EG: it is defined in "delegates.xml" and not as a 'coder' module.

I myself also have a "remote:" spawning delegate that 'updates' a currently running "display" program.
If no display is running it will run one, but generates an error message in the process: -(

One of my ToDo items in IMv7 is to fix a definaite 'slowness' in the delegage spawning process. Their is not need for it to take 2 to 3 seconds to 'spawn' as background process, and still ensure that program has read its input image.

Unfortunately I don't know the differences. So I look at everything (from a functionality rather than coding point of view) that ends with a colon ":" as either a pattern, built-in image format or pseudo-image format.

Pango color formating is now working, at least for IM v6.7.6-3. You do not need to set the pango:markup define, as this is on by default.

Denisty control for the font Pango uses is also working.

Note that font selection is not, and I have a feeling you can not control this as pango uses multiple font libraries for bold, and italic selections.

I have not tried any of the other pango defines listed in the documentation (or in the coder itself).

I have uploaded (appear in an hour of so) some initial pango examples.
