@C1@c@b@_ Image Merge
To merge/concatenate two or more images to form a single image.
@b Interaction
Click on Image2M to load the image to be merged.
Click on the appropriate alignment buttons for the merging location.
By default, images are concatenated with empty region filled with a
fill color, changeable by clicking on the FillColor button.
The slider on the bottom of the control panel controls the separation
from the current image, thus a negative value will merge the image into
the current image. For the overlapping part, by default, the new image
overwrites the current image. Click on the top/bottom button to
change this default.
Other operations for the overlapping part is possible by clicking
on the topmost box on the right side of the control panel. Current
operations include (A: current image. B: image to be merged)
@f OverWrite: B
@f Add: Min(B+A, 255)
@f Sub: Max(B-A, 0)
@f Diff: Abs(B-A)
@f XOR: B^A
@f Mask: B?B:A
Exchange A&B when top/bottom setting is bottom.
The auto placement can be disabled by click on the Manual button,
then use mouse, ijkl or arrow keys to change the merge location.
Click on Merge button to initiate merging. By default, all alignment
is against the original image. To update alignment referenc, click
on UpdateSize button.
Click on Done to finish.
@b Note
1. Resulting image will always be in RGB.
2. You can merge the same image repeatedly.
3. The size update can be a little tricky, for example, to concatenate
four identically sized images, the only way (without manual
placement) to do it is to concatenate the first two then update
size, do the remaining two without size update.
