ImageMagick change colorType of PNG image

[Hieung28]

My original image has colorType = TrueColor. After loading and processing it with ImageMagick and writing it to a new file, the new file ends up with colorType = Palette. I know this is the way ImageMagick optimizes output by default, but it affects my work. Is there any way to preserve the original colorType?

You should be able to control this with the ColorType property of the PngWriteDefines that you need to pass to the Write method.

I dont see PngWriteDefines class. Do you mean i have to create this class ? Very appreciated if you have example for this.
I'm using version MagicK.NET-Q8-x64 (13.3.0.0)

You will need to add ImageMagick.Formats to your using's
