问题 I have used gmt to create several .ps files of x - y graphs with identical axes. I have several sets of data, each containing between 14 and 20 plots. Each plot is in a separate directory.

问题 I have a simple 2D game with a handful of characters which move around the screen. I'd like to create a fog of war, whereby only the background around each character is visible.

Then I can draw the background, draw the characters and finally draw this overlay bitmap over the top. Just not sure how to draw the 'transparent' disks on to the

I have the images, and the onclick handler working, just trying to figure out the best way to apply the overlay. thanks 回答1: Not very pretty semantically, but should get the job done : Let's say your imgs are 200x200.
