OOF2: The Manual
Pixel Info (PixelInfoDisplay) — Display a pixel that is being queried.
PixelInfoDisplay highlights the
Image pixel currently being investigated by the PixelInfo toolbox in
the Graphics Window by drawing a box around the pixel. The
line_width parameter is in units of the screen
pixel size (which is not necessarily the same
Image pixel size!).
PixelInfoDisplay is created
automatically in each Graphics
Window and is not normally visible in the window's layer
list. To edit its properties, first select List
All Layers in the graphics window's Settings menu.
