I suggest you include an error handler, and print the exception error message it gives.
I tried to put the whole code in try catch statements but still not able to catch that exception.
Sorry for novice questions, but i'm new to c++.

Writing grayscale image in single channel IM7

Can anyone please guide me, how do I write a grayscale image in single channel in IM 7+ version.

I've tried

Code: Select all

 
 	image.type(GrayscaleType);
 	image.colorSpace(GRAYColorSpace);
 
But, couldn't get final image as single channel image.

What version of IM?

My image in pixel data is 8-bit grayscale image. But, magick++ is writing it as 4-bit image from the above code. Please tell me where I'm going wrong.
