Jeff Segars pointed out a nice little application to me called xScope. It is a collection of utilities that allow you to get information about things on your computer screen. Among those utilities are:
- Frame overlays to show the cropping of various screen resolutions
- Ways to view and copy the color values of items.
- On-screen rulers
- Methods to measure distances and dimensions of items on screen.
- A loupe to make it easier to read values of individual pixels.
I have particularly found this application helpful in my front-end coding.
Keep in mind that if you want to use xScope to capture accurately the color values within a Photoshop document you will need to do the following in Photoshop:
- set View->Proof Setup to "Monitor RGB"
- activate View->Proof Colors.
Failure to do so will cause Xscope to read to color values which PS has biased according what is entered in its "Color Settings" dialog box.
