I don't use Magick.NET, but your code seems to composite finalImage over spotImage. I suspect you want this the other way round. Your command doesn't contain the keyword "-composite" so it won't do a composite. Yeah, that was incorrect. I inverted the command line, but, the result was the...

Hello everyone. I'm trying to composite one image on the top of the another. However, when i use the following code: using (MagickImage finalImage = new MagickImage("backgroundimage.png")) { using (MagickImage spotImage = new MagickImage("imagetocomposite.png")) { spotImage.Compo...

A grayscale image has only one channel. I need to change the values on a rGB scale or CMYK scale. I got an method that uses unsafe code (pointers to the memory) for doing that ; however, it's still slow for doing all the stuff. I think MagickNET can be faster. Should i delete this topic, since it is...

Let me see if i got it correctly.

My goal: After set the image ColorSpace to CMYK , set the channels individually on the image. IM won't do that ?
Ex:
1 - Set the image colorspace to CMYK
2 - On some pixels , i want C(0), M(0.3), Y(0.1), K(0)

The screenshot came from Visual Studio 2015 (Community Edition, Free)

The syntax is correct. using (MagickImage testImage = new MagickImage(@"C:\inputfolder\testimage.png")) { testImage.ColorSpace = ColorSpace.CMYK; } I'm not using the command line interface, i'm using the .NET Wrapper. After set the ColorSpace to CMYK, when i try to access the channels they...

Hello everyone. I've noted this today. When you set the ColorSpace to CMYK, you expect the channels to be "Cyan, Magenta, Yellow, Black". However, it isn't being that way. I attached an screenshot, where channels can be clearly see as "Cyan , Green , Blue, Black". Even when i set...

I'm using the following code trying to change the pixel color: //small test: just a really small image to debug and check pixel values using (MagickImage spotImage = new MagickImage(@"C:\test\small-test.TIF")) { spotImage.ColorSpace = ColorSpace.CMYK; using (PixelCollection pc = spotImage....

My current try: ushort c_CMYK = 0; ushort m_CMYK = 100; ushort y_CMYK = 100; ushort k_CMYK = 0; using (MagickImage spotImage = new MagickImage(@"C:\inputfolder\8FILES_IMPOSED_4UP_BACK.PDF (Imposition)00.TIF")) { spotImage.ColorSpace = ColorSpace.CMYK; using (PixelCollection pc = spotImage....

First step : combine all 4 cmyk images Second: Add this square cmyk image onto it This is part of my app. It's a preview of the image that is going to be print (industrial printers , large scale). EDIT: I believe what i'm need to do is to composite the image. Thats it. After converting the Impositio...

I forgot to post. This is the current code i have: using (MagickImage spotImage = new MagickImage(@"C:\DI_PLOT\Bitmaps\8FILES_IMPOSED_4UP_BACK.PDF (Imposition)00.tif")) { float[] cmyk = new float[4]; cmyk[0] = 0; //C cmyk[1] = 100; //M cmyk[2] = 100; //Y cmyk[3] = 0; //K //Converting to RG...

Hello everyone. I have an image, that is just an empty square. The image is a TIFF Grayscale, an negative of an specific CMYK color. This CMYK color, is composed by (example): 0% C 30% M 20% K 0% Y I know i can't create an CMYK color on the .NET interface, however, i've found the following calculati...

30 seconds sounds a bit long but with the images your provided me it will take a while and require quite a lot of memory. Are you using the x64 version or the x86 version of Magick.NET? If you are using the x86 one you might want to give the x64 one a try. And you really don't need to change the Co...

With the latest version (7.0.5.500) I was able to get the same output as on the command line with the following code: using (MagickImageCollection images = new MagickImageCollection()) { images.Add("8FILES_IMPOSED_4UP_BACK.PDF (C)00.TIF"); images.Add("8FILES_IMPOSED_4UP_BACK.PDF (M)0...
