[mmtext] [Up] [mmlimits] | Image Information and Manipulation |
Implemented in Python.
DIM | String Dimension to concatenate. 'WIDTH' or 'W', 'HEIGHT' or 'H', or ' DEPTH' or 'D'. |
X1 | Image Gray-scale (uint8 or uint16) or binary image. |
X2 | Image Gray-scale (uint8 or uint16) or binary image. |
X3 | Image Gray-scale (uint8 or uint16) or binary image.
Default:
|
X4 | Image Gray-scale (uint8 or uint16) or binary image.
Default:
|
Y | Image Gray-scale (uint8 or uint16) or binary image. |
Concatenate two or more images in any of the dimensions: width, height or depth. If the images do not match the dimension, a larger image is create with zero pixels to accommodate them. The images must have the same datatype.
>>> f1=mmreadgray('cameraman.tif')
>>> f2=mmreadgray('blob.tif')
>>> g=mmconcat('W',f1,mmgray(mmneg(f2)))
>>> mmshow(g);
