PixelPerfect

Compare mockup design images with a user interface on iOS, get the diff of images using inversion or transparency of design mockups.

##Features

• show a mockup image imposed with a user interface
• change a mockup image transparency
• invert colors of a mockup image to see design difference

##Usage

1. Copy mockup design images to project.
2. Create dictionary with class name and corresponding mockup image name.
3. Instantiate PIXELPerfect with this dictionary in application delegate class.
