Image display

Franz Reitner
Hi all,

This questions has already been sent two months ago and I've got no answer till now. So I'll ask again:

I've got a small problem with image display. While doing a live view, acquired RGB images are displayed inside a window. So far so good.

In case I try to set brightness and contrast the new b&c is reflected in the window as long
as I get and set a new acquired image from within my plugin. While doing the same with an 8bit bw image it works.

So, who overwrites my b&c setting while doing rgb? Any thoughts?

Regards,

Franz

Hi Franz,

there is a fundamental difference between B&C for grayscale and RGB:

Grayscale: B&C modifies the way how the image is displayed, the image  
data remain untouched.

RGB: B&C modifies the image data. This means:
- Any operation done after B&C uses the modified (adjusted) image.
- If you change the image data (in a live view), the new image won't  
know anything about the B&C adjustment done on the previous image.
