Ah, yes, I hadn't taken my tests quite far enough. When the images are all colour (more specifically, the same type), Gimp can open them all as layers. That's a great tip to know. I could never figure out why I couldn't make a tiff out of both a photo and a greyscale mask and open them together as l...

When the images are in colour, with +compress, I see almost no difference in file size. Version 6.8.6-5 and 6.8.3-0: "%IMG6865%convert -size 500x500 -depth 8 xc:pink xc:red gradient:white-blue xc:green +compress out.tiff "%IMG683%convert" -size 500x500 -depth 8 xc:pink xc:red gradient...

It fails for me: IM v6.8.6-5, Gimp 2.8.2, on Windows 7.

In Gimp, I can open all the images as separate images. But when I ask to open them as slayers, I get only 2 layers.

When I create my tiff with an extra layer, Gimp can still open only 2.

It worked fine in 6.8.4-0.

Sorry, it's been too many years (decades?) since I used IIS.

Maybe it's worth trying a simple gs command from PHP, something like:

Does the command that converts from a PDF work from the prompt? If not, then that needs correcting. Otherwise, it's a server configuration problem.

v6.8.6-5 on Windows 7 doesn't seem to embed profiles in jpegs. >set I=%IMG6865% >%I%convert -version Version: ImageMagick 6.8.6-4 2013-07-08 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2013 ImageMagick Studio LLC Features: DPC OpenMP Delegates: bzlib djvu fftw fontconfig freetype jn...

This isn't about Conditional Resizing, so start a new thread. And supply an example image.

This image is made for the web and the output image is lighter than it should be (I use Google Chrome - if this makes any difference?)... I don't have your old version of IM, or any version of PS, but it might be a gamma problem, aka RGB/sRGB. If so, then sprinkling "-set colorspace sRGB"...

Unsharpen is supposed to ignore 'special convolve specific' user settings such as -channel, -bias and convolve defines. Perhaps it's supposed to ignore -channel, but it doesn't, as I showed above. A more specific example: convert -size 100x50 xc:gray(25%) xc:gray(75%) -append -channel R -unsharp 0x...

The script looks to do what we need but im unsure if i can call it through IM ? and if so would you know how i could call the script using IM ? Scripts call IM programs such as convert. IM programs don't call scripts. If I understand you, you take a PSD image (which might have CMYK or RGB channels)...

I know nothing about PHP, so can't help there. However, the message "Must specify a file system" comes from Microsoft convert, a utility that converts one filesystem into another. So your script successfully calls a program, but the wrong one. As suggested, putting the full path to ImageMa...

Apart from size, what's the difference between output3.png and output.png?

Try:

I don't have 6.7.7-10, but may be able to find a solution that does what you want on that version. But I don't know what you want. icon.png has aliased black letters on a transparent background. The background is transparent black near the letters; otherwise transparent white. What result do you wan...

I don't know why "-unsharp" seems to blur the alpha channel. But you can prevent this from happening:
