Hello everybody,

I found out how to get left/right shift with ImageAnalyzer.
You can use Image -> Combine Images -> User Expression
and use the p1/2 expression for a rightshift of 1, p1/4 for a
rightshift of 2, etc.. Leftshift is obtained by p1*2, p1*4, etc..

@Michael, do you think the bitmanipulation functions from above
could be in a future version of ImageAnalyzer?

Good morning,

well, it s not that strange, maybe I didn t explain it properly ;-)

Imagine folowing industrial image processing problem:
There are binary (black/white) images of simple prints like a logo.
You can monitor the quality of the print by comparing the "accumulated row/column profiles"
of consecutive images.

Here is a Java Applet with this function:

Hi Michael,

the profile plugin is very useful and I haven't seen any other image processing
soft with this function built in.

An extension which comes very handy on binary images is the accumulated profile.
This is the sum of the row/column profiles over a certain area.
Maybe this is this a feature you decide to include in one of the next versions.

Hi Michael,

I am using ImageAnalyzer for digital image processing purposes and like its functions a lot.
Anyway it would be great to have some low level bit manipulations available.
Something like:

-left/right shift
-split image by bitplanes / combine image from bitplanes
-min, max color values
-count colors and list them
-switch on/off one ore more bitplanes
-toggle bits
-create image with complement set bits

Another nice feature would be a color picker which shows the color/grey value simultaneous in
hex, binary, decimal, octal and maybe the corresponding ascii character (if there is one) in a little info box.


Thanks a lot,

aboy

Edit: I keep adding requests to this thread if related to bitoperations
