Can't read MPC files properly? [magick++]
Posted: 2006-06-22T17:19:28-07:00
I have a rather large library of square images. I want to both display these images to my users over the web as well as do work on them. Thus, I have stored every image in 2 ways: img.png and img.mpc. (4 ways if you count the fact that I have two sizes of each image.)
In my code, I have the following command. It's only purpose is to open the source image for work:
imgs is a stl vector<Image>. size is an integer indicating the desired image size (one of two values) and the char* is the file extension.
For some reason, when I change the file extension to "mpc", the image fails to open properly and my output (a composite of my source images) ends up all black. If I keep it as "png" it works just fine.
There is no difference in the naming schemes between the mpc and png files save for the extension. Running a 'convert' command from the command line seems to show that the mpc files are encoded just fine - the output will look like a normal png:
Anyone have any ideas?
