Hello, I have been developing over ImageMagick (using Magick++ API) for over a year, on Win XP. I am planning to port the same version (6.6.0-7) to Win 7. I cant reach the documentation of version 6.6.0-7 to check its full Win 7 compatibility. Would anyone give any information about Win 7 support of...

For instance "C:\target.jpg" is not valid while "C:\\target.jpg" is valid.

Hi again, i can now write an image to file by giving a target path manually, inside the code; but it wont write the image when the target is a dynamically allocated local string pointer. For instance, in my save() method, the following piece of code works img = new Image("lena.jpg"); img->...
