error C3861: 'AcquireImagePixels': identifier not found
Posted: 2008-07-28T06:16:53-07:00
Hi all!
I am new on Magick++, so I need some help for start. I wrote this simple code that load an image from command line and then create a pixel cache to access pixels in read-only. I found out that the line with AcquireImagePixels doesn't compile with error on Visual C++ 2008 Express Edition:
error C3861: 'AcquireImagePixels': identifier not found
but using getConst instead it works. Why?
Thank you all for help
