-
- To create drawings of various sizes, use vgconst to create a background
- of whichever size you want to have and use it as input to editimage.
- To save your annotation drawings as a viff image, you must combine
- them with the background image by clicking on 'COMBINE ANNOTATIONS'
- under the 'IMAGE UTILITIES'-menu.

-
- This seems to be a general problem with the algorithm for the roi bar
- colors. Currently the displayed roi bars simply have the inverted colours
- of the image as it displays AT THE MOMENT OF ACTIVATING THE ROI. This
- means that depending on your screen configuration, they might not at all
- have meaningful colours when you enter the image with the mouse. You
- can change this behaviour by hacking the routine
- $KHOROS_HOME/src/xvroutines/Lib/xvdisplay/roi.c around line 344.
-
- (Hey Mark, do you read this? Sounds like the first drawing of the bars
- should be changed to occur on enter_notify of the raster image, right?)
-
- Hope this helps,
