Thanks for your quick response, the font size should change in the Help window as well, I have found why it did not and fixed it. I was treating IM warnings as errors! I have now made warnings create a string with the warning text, i.e. no dialog to close if it happens in a long run. An updated exe ...

I am currently developing a program which acts as a front end for Image Magick and several other image processing packages, OCV, VTK, POV etc. The result has about a thousand functions that you can combine to do many image related tasks. This is, and will be free software. I am wondering if there is ...

I have IM version 7 compiling without trouble on Windows 7, using the free Microsoft Visual Studio Community 2013 edition, I just unzip the latest Beta version and run the precompiled setup program, thank's to everyone concerned.

I have however found a couple of problems.

1. It appears that the ...

I have now solved this problem, I had handled the Read Mask incorrectly in my display routine so that its Traits were not valid. I find it a little odd, but not important, that one out of the four functions mentioned did not have a problem and the other three did.

Apologies if you know about this but I was just playing with ImageMagick-7.0.0-0~beta20150320-windows. When trying the Magickcore functions FlopImage(), FlipImage(), TransverseImage() and TransposeImage() with some RGBA images only the FlipImage() function works as expected.
The other functions give ...

I have a more or less working program which includes most IM functionality. But since starting the project I have decided to expand it somewhat. I have changed from Windows to Qt, I am developing it on Windows so it will run there but Qt programs can be recompiled for other OSs as well such as Apple ...

Yes I noticed that the probable release date was getting further into the future, no problem. I have not released my prog for testing to anyone yet and when I eventually do I will emphasise that it and IM are not ready for final release, I hope to synchronize its official release with that of IM ...

I would like to give the user of my program a chance to add user channels to an image by specifying the number they need. So I am building a Channel FX command string in C++ and I have discovered an oddity, am I doing something wrong, is this by design or is it a bug? My code looks like this:-

char ...

I have downloaded and linked to a recent version of IM7 and both of my problems seem to have gone away, thank's.

I am using the Magick Core functions so I do not have a script but I have done a bit of digging in the IM code, and tried a very crude patch to test my theory and it seems to work.

in the file "transform.c" is the function I tested "ExcerptImage", several other functions have a similar problem ...

Since writing my original post I think I have worked out what is going on with the random pixels.

When a new image is created from a source image that has a Read mask first a memory buffer is allocated for the destination image, this is not initialized so may contain anything. Actually in debug ...

I am still developing my Windows program that exposes most of the functionality of IM 7 (and some other libraries two, VTK and open CV). I hope to release a test version when the IM beta is available. I have managed to static link my program, to avoid having to distribute dozens of .dll files.

IM 7 ...

I have been trying out some Channel FX operations and have a few comments. I know that you are going to expand this functions capabilities, but still had to have a p[lay.

Extracting individual channels, e.g. R G and B, to greyscale images works fine with this string "1;2;3" but when using the ...

To pass into various functions. For if I want to draw a red circle I could use something like "fill #ff000000 circle 50,50 10,50" in the sRGB colour space it works fine but in any other the #ff000000 needs to be something else. I realize that I can't use named colours in a Draw string because there ...

Thank's but I was looking for a general method, I have used the one pixel method mentioned above and it works OK for most colour spaces, the two that fail in a major way are GREY and YCC, LMS shows a slight change. But as I know nothing about colour space things in general, just following my nose, I ...
