I have looked at various montage macros for creating composite mosaics
from overlapping images, and wanted to try something simpler using
"imageJ/Stacks/Make Montage". Since my image offsets required for
registration are constant, I can modify the MakeMontage.txt macro to
offset the image rectangles before pasting.
This works fine, but instead of the default "Paste Control" (Copy) I
would like to use Blend, but ***only for the overlapping regions***.
(Otherwise Blend blends the non-overlapped regions with the white or
other background).
newImage("test", type+" black", columns*getWidth, rows*getHeight, 1);
iw=getWidth/columns; ih=getHeight/rows;
x[0]=0; x[1]=-25; x[2]=0; x[3]=-25; // image offsets for registration
y[0]=0; y[1]=0; y[2]=-75; y[3]=-75; // image offsets for registration
montage=getImageID;
selectImage(id);
for (i=0; i<4; i++) {
selectImage(id);
setSlice(i+1);
run("Select All");
run("Copy");
selectImage(montage);
makeRectangle((i%columns)*iw+x[i], floor(i/columns)*ih+y[i], sw, sh);
run("Paste");
}
I am relatively new to imageJ macros but am excited by the possibilities.
