Hello, I am doing convolution in C# core by using ImageMagick.Convolve() function. When I doing the convolution manually, I got totaly different result. The library is Magick.NET-Q16-x64. I am using this library for 12 bits depth. When convolution is over 4095 (2^12 - 1) or less than zero, I ...

Hello, I have a picture of 1000k x 1000k pixels. The picture may come in format jp2 or tif . I want to write a block of area , i.e 30k x 30k on the big picture (don't has to be that size exactly - if I can write to specific areas, such as tiles - it's ok), without load the picture into memory. I ...

Same exception: 'magick' is not recognized as an internal or external command I didn't do any magick installation outside visual studio - just installed it by visual studio 2017 -> manage nuget package. This is forum for magick.net, so I persume that it's OK to post here. I am not using c++ directly.

I don't understand. I am new to magickImage. In visual studio 2017, where can I write magick -version? In package manager console I wrote: magick -version and got the exception: magick : The term 'magick' is not recognized as the name of a cmdlet, function, ... As I said, Magick.NET-Q8-x64 ver 7.8.0 ...

For very big image - I assume that "tiles" (area of the picture) can solve the problem, and I can handle and save each tile separately. (maybe that is TIF and JP2 for). If that solve the issue, I also assume that for 100000 x 10000000 pixels ImageMagick doesn't encounter memory overflow when ...

Magick.NET-Q8-x64 ver 7.8.0. I think it is OpenJP2. I don't know how can I declare parallelism (Maybe: MagickImage mi = new MagickImage (...) mi.Settings.<something> ? solve that issue) i.e how many threads, and not doing this by myself (let imagemagick handle that). For Convolve function - I need ...

Hello, 1. How can I parallel work of MagickImage.Convolve(...) so it will work on several threads. Can I control what behind the thread (i.e for first thread - i want to know which area is responsible by the thread, and even send this information to other processes). 2. I need to load the image and ...

Hello, In my code I did: MagickImage im = new MagickImage(<my file name>); IPixelCollection pc = im.GetPixelsUnsafe(); ... The image is grayscale so it has 2 channels, but I want to fast convert it to 3 colors (and save the binary data - only the byte array of rgb to file). Also convert to 1 color ...
