TCel for Mac

TCel empowers front-end Web developers to get their webpages pixel perfect. While laying out a webpage, overlay an image on top of Safari or other web browsers and truly match what your graphic designers intended.

Features:

• Supports many image formats like PNG, PSD, AI, and JPEG
• Control the opacity of the image overlay
• Use keyboard arrow keys to exactly position the image overlay
• "Ignore Mouse" to click through an image and interact with applications underneath
• Invert an image where color differences are hard to make out with the naked eye
