I'm trying to use a Locator
for some image processing tasks. Unfortunately, the images we're using have a high dynamic range of low-frequency black and white features. I've made a custom Appearance
for the Locator
with some concentric circles that works pretty well, but am wondering about using other compositing operations instead, like, Xor.
The current implementation of Locator
seems to composite with a simple Over operator. Meaning that the 'cross hairs' disappear on black patches.
Has anyone successfully created a more dynamic locator appearance or have some thoughts about how one might do that?
