Re: String manipulation methods for EXIF tags

And how about something like: "%[EXIF:DateTime:dd.mm.yyyy]" which is just for the EXIF tags, not for ANY string constant, if it's so difficult?
I have never used them, but there are DateTime tags for EXIF. See http://www.imagemagick.org/script/escape.php

Re: Manipulating Print / Document Size Issue

Take a look at -resample http://www.imagemagick.org/script/comma ... p#resample and http://www.imagemagick.org/Usage/resize/#resample

I am no expert at this kind of thing, and I will defer to the experts, but I think this may be what you need.

Re: circle parameters

Yes, I would love to see that also. It makes sense to me, too.

But the IM developers are very busy with backlog of things to do. It would be great if there were other software developers willing to contribute some time to such development.

Re: exposure compensation?

you need to explain how you want to correct the overexposed image for step 2, that is what is the formula or processing that you need to do

Re: Controlling background color of transparent PNG?

if your background is actually transparent, then try

convert image.png -fill white -opaque none output.png

But then all transparent areas will become white

Re: possible bug in converting to gif in IM 6.4.1-5 (still)

Actually, I have no idea. But the point is that under IM 6.4.1-3 HDRI it only took 0.4 sec, but under IM 6.4.1-4 and 6.4.1-5 either Q16 or Q16-HDRI, it took over a minute. See timings above. So something has changed for the worse since 6.4.1-3

Re: circle parameters

in a shell script you could do:

radius=40
x0=some value
y0=some value
x1=`expr $x0 + $radius`
y1=$y0

convert ... -draw "circle $x0,$y0 $x1,$y1" ...

Re: Problems with EXR under Windows

see http://www.openexr.com/index.html http://www.openexr.com/ReadingAndWritingImageFiles.pdf Note IM only supports the "half" format and not the full 32-bit floating point format. You need to download and install the EXR delegate. Once you do that you can check to see that it was installed after you...

Thanks. Whenever you can get to it.

By the way, did anyone bite-off on trying to speed up -fx?
