New Post: Resize filter parameters
Hi Magick.Net
Filter Function group to use it for image resize was not found.
I hope for the addition of the functions. thanks.
example,
http://www.dylanbeattie.net/magick/filters/result.html
MagickSetImageArtifact(wand, "filter:lobes", 4)
MagickSetImageArtifact(wand, "filter:window", FilterTypes.Sinc);
MagickResizeImage(wand, 1280, 800, FilterTypes FilterTypes.LanczosFilter, (double) 1.1);
convert in.png -resize "1280x800" -filter Lanczos -blur 1.1 -define filter:window=Sinc -define filter:lobes=4 out.png

You will be able to set the filter options when the following work item has been completed: https://magick.codeplex.com/workitem/1027. I will add a method called 'SetArtifact' to MagickImage.

New Post: Using MagickImage.AddProfile() with ColorProfiles and problems with RemoveProfile()
I'm struggling to use MagickNet to colour-correct images. My wide-gamut monitor requires that images be colour-adjusted if they are not to display extremely exaggerated red hues.
So, I have been experimenting with using MagickImage.AddProfile() to apply a new ColorProfile to images, that I create by loading my monitor's colour profile from disk. At first this seemed to be working, but then I realised that it was only having an effect for images that already have the sRGB profile applied (or, it would seem, any other profile). Non-colour managed images are not affected by adding the monitor profile.
I just can't understand why it would be necessary for an image to have a colour profile already applied to be affected by applying a new, different one.
Additionally, RemoveProfile() appears to have no effect. In the following code, the call to RemoveProfile does nothing.

New Post: Applied ColorProfiles not having an effect on MagickImages
I am not an expert with color profiles but maybe you can get the same result if you first add the sRGB color profile (ColorProfile.SRGB) and then add your own. I have also tested the code you posted and in my unit test it removes the profile. The next call to image.GetColorProfile() will return null.
↧
New Post: Applied ColorProfiles not having an effect on MagickImages
I had actually already tried manually setting an sRGB profile just as you suggested, but it made no difference. It seems to need to be embedded in the image file to begin with. To be clear, this is what I am currently running:
As for RemoveProfile(), I have played around a bit more. It seems to work only on profiles that were added programmatically. In other words, it will remove a colour profile that was previously added with AddProfile(), but it will not remove a profile that is associated with the image in the file on disk that the image was read from.
image = new MagickImage();
image.Read(@"E:\test.jpg");
image.AddProfile(ColorProfile.SRGB);
image.AddProfile(new ColorProfile(@"C:\...\LP2475w_20090407.icc"));image = new MagickImage();
image.Read(@"E:\test sRGB.jpg");
image.AddProfile(new ColorProfile(@"C:\...\LP2475w_20090407.icc"));As for RemoveProfile(), I have played around a bit more. It seems to work only on profiles that were added programmatically.

New Post: How to define floating point format
In the image format listing on the ImageMagick website, the format GRAY says to use single precision floating point format use -define quantum:format=floating-point
And in the Magick++ library Image contains a constructor where you can specify StorageType
How is this done with Magick.net? Or do I have to cast them to UInt16 and then to a byte[]

Hi,
I am unsuccessfully trying to give color to a mask. From the ImageMagick documentation I found there are a few ways to do this. How can I achieve any of the following with Magick.NET?

New Post: Converting mask to color
Yes. I'm basically trying to generate some of the jQuery UI icon images. The mask has a typical black background with the icons colored white, and I want to color the white icons blue let's say on a transparent background. Could you please give me a code snippet as well through which I can achieve this? I think I tried using ColorAlpha but it did not appear to work. Regardless, I'll try again.
Thank you for your prompt response.

Can you post your image somewhere, so I can do some tests with it? I am now working on some changes for the next release and that includes adding the method LevelColors (http://www.imagemagick.org/Usage/color_mods/#level-colors). I think this is the method you are looking for.

Sure. The image is:

Yes I read about the LevelColors method as well. I would be great if that were available. Thank you.

I will add both Alpha and LevelColors. After the next release that I will publish this weekend you will be able to do this:
// Background purple, foreground yellow.using (MagickImage image = new MagickImage("mask.png")) { image.LevelColors(Color.Purple, Color.Yellow); image.Write("mask-ithurtsmyeyes.png"); } // Background transparent, foreground blue.using (MagickImage image = new MagickImage("mask.png")) { image.BackgroundColor = Color.Blue; image.Alpha(AlphaOption.Shape); image.Write("mask-blue.png"); }
