Ignore this guys, there was a problem with the dlls I had in my output directory.

I'll assume magick's response was @dlemstra, but to clarify this is v7.0 When I tested on linux it was downloaded as a zip file (as I can't seem to checkout from the repo to a VirtualBox hosted linux installation). I couldn't find a v7 download with the necessary VisualMagick additions to let me ...

I'm just testing out the new channel stuff in the beta version with the following code: #include <Magick++.h> int main(int argc, char** argv) { Magick::Image image("wizard.jpg"); MagickCore::Image* coreImage = image.image(); for (int i = 0; i < image.channels(); ++i) MagickCore::PixelChannel channel ...

This sort of code isn't how to use the Magick++ API. You'd do something like #include <Magick++> using namespace Magick; using namespace std; ... // open an image Image image("some_image.jpg"); // perhaps do something to the image image.resize(Geometry(500,500)); // will hold the image data in ...

I want to be able to create a Magick::Image instance from an SVG file, rendered to a certain size. I can render SVGs to different sizes from the command line using something like convert -density x infile.svg outfile.png and tinkering with x until I get the desired size, but I can't seem to be able ...

I have everything working now. I'm using Magick++ and was making no progress for a long time as I was using instead of I guess this doesn't really belong in bugs then? Or would you prefer it stayed here and I marked it as [INVALID] or something?

Thank you!!

Thanks

Thanks, I don't mean to sound impatient

Does anyone in authority have any comment on this? I'm working on a project predicated on the notion that the colours are preserved, and will have to rethink the design radically if this assumption is unfounded

Cheers

Q16 6.8.0-7 64bit on Windows Remapping this image with this colour map results in an image which contains a colour that doesn't appear in the colour map (namely rgb(101,4,1)) commands used were: convert.exe InputImage.tif -remap ColourMap.tif Remapped.tif convert.exe ColourMap.tif -unique-colors txt ...

If g mapped the original CMYK image to sRGB then the desired map f would be defined by http://s8.postimage.org/mfr9djb6d/Code_Cogs_Eqn.png for each colour i. I think the ICC profile sounds like the way to go. This would mean the ICC profile would be a function of the original image, so I would need ...

Does anyone have any more thoughts on this or want to come to the defense of the dithering results above?

Hopefully this will be an interesting one... We have an image in CMYK (with ICC profile), with a limited number of colours having special, fixed values in each of the 4 channels, (e.g. C=0%, M=0%, Y=100%, K=100% as well as C=100%, M=100%, Y=100%, K=100%). We need to be able to convert this to sRGB ...

Thanks for the reply. I'm afraid +dither is not an option, the image has to be dithered using Floyd-Steinberg or similar. Using a darker colour map doesn't seem to help either, and besides IM should be able to do better than that with the above map. There is clearly not enough black on the wall to ...

I'm using using IM to do things related to printing so it's important that the hard work put into getting the image colours correct isn't undone by me messing everything up when I process them :P I'm attempting to dither an image to a colour map (that will represent the possible ink combinations ...
