8.5. Append Image Geometry
Group (Subgroup)
Sampling (Memory/Management)
Description
This filter allows the user to append one or multiple image geometries to a given image geometry, in any direction (X,Y,Z). The input and destination ImageGeometry objects must have the same dimensions in the directions that are NOT chosen. If the X direction is chosen, the geometries must match in Y & Z. If the Y direction is chosen, the geometries must match in X & Z. If the Z direction is chosen, the geometries must match in X & Y. Optional checks for equal Resolution values can also be performed.
This filter also has an option to mirror the resulting geometry in the chosen direction. If the X direction is chosen, it will mirror the positions of the YZ planes. If the Y direction is chosen, it will mirror the positions of the XZ planes. If the Z direction is chosen, it will mirror the positions of the XY planes.
X Direction Examples
Example 1 (X)
If the user has an already existing Image Geometry that is 100 voxels in the Y direction by 300 pixels in the Z direction and composed of 10 X slices, then if the user appends another three geometries in the X direction that are the same dimensions in Y & Z but contain 20 X slices each, the resulting Image Geometry will have a total of 70 X slices.
The filter inputs for this example are as follows:
Input Image Geometries: Geometry A (20x100x300), Geometry B (20x100x300), Geometry C (20x100x300)
Destination Image Geometry: Image Geometry (10x100x300)
Direction: X
Mirror Geometry In Direction: OFF
Check Spacing: OFF
Default Value: 0
Save As New Geometry: OFF
Example 2 (Visual Example) (X)
Here’s the SmallIN100 dataset example sliced into three pieces in the X direction:
And here is what the geometry looks like after appending the three pieces together in the X direction. On the left is the regular result, on the right is the mirrored result:

Y Direction Examples
Example 1 (Y)
If the user has an already existing Image Geometry that is 400 voxels in the X direction by 200 pixels in the Z direction and composed of 50 Y slices, then if the user appends another two data sets in the Y direction that are the same dimensions in X & Z but contain 40 Y slices each, the resulting Image Geometry will have a total of 130 Y slices.
The filter inputs for this example are as follows:
Input Image Geometries: Geometry A (400x40x200), Geometry B (400x40x200)
Destination Image Geometry: Image Geometry (400x50x200)
Direction: Y
Mirror Geometry In Direction: OFF
Check Spacing: OFF
Default Value: 0
Save As New Geometry: OFF
Example 2 (Visual Example) (Y)
Here’s the SmallIN100 dataset example sliced into three pieces in the Y direction:
And here is what the geometry looks like after appending the three pieces together in the Y direction. On the left is the regular result, on the right is the mirrored result:

Z Direction Examples
Example 1 (Z)
If the user has an already existing Image Geometry that is 100 voxels in the X direction by 200 pixels in the Y direction and composed of 5 Z slices, then if the user appends one other data set in the Z direction that is the same dimensions in X & Y but contains 10 Z slices, the resulting Image Geometry will have a total of 15 Z slices.
The filter inputs for this example are as follows:
Input Image Geometries: Geometry A (100x200x10)
Destination Image Geometry: Image Geometry (100x200x5)
Direction: Z
Mirror Geometry In Direction: OFF
Check Spacing: OFF
Default Value: 0
Save As New Geometry: OFF
Example 2 (Visual Example) (Z)
Here’s the SmallIN100 dataset example sliced into three pieces in the Z direction:
And here is what the geometry looks like after appending the three pieces together in the Z direction. On the left is the regular result, on the right is the mirrored result:

Input Parameter(s)
Parameter Name |
Parameter Type |
Parameter Notes |
Description |
|---|---|---|---|
Input Image Geometries |
MultiPathSelection |
The incoming image geometries (cell data) that will be appended to the destination image geometry. |
|
Destination Image Geometry |
Geometry Selection |
Image |
The destination image geometry (cell data) that is the final location for the appended data. |
Direction |
Choices |
The direction that will be used to append the geometries. |
|
Mirror Geometry In Direction |
Bool |
Mirrors the resulting geometry in the chosen direction. |
|
Check Spacing |
Bool |
Checks to make sure the spacing for the input geometry and destination geometry match |
|
Default Value |
String |
The default value that will be used if a data array does not exist across all geometries to be combined. NOTE: This is a string value that can be set to anything, HOWEVER, the filter will return an error if the string value cannot be converted to the proper type for any missing arrays. For example, if you have a 32-bit signed integer array that is missing in some geometries and you set the default value to ‘abc’, the filter will return an error since ‘abc’ cannot be converted to an integer. If you set the default value to ‘256’ and you have an 8-bit unsigned integer array that is missing in some geometries, the filter will return an error because 256 is outside the range of an 8-bit unsigned integer (0-255). If the only missing arrays happen to be string arrays, then in that case ‘abc’ would actually work as a default value. |
|
Save as new geometry |
Bool |
Save the combined data as a new geometry instead of appending the input data to the destination geometry |
|
New Image Geometry |
DataGroupCreation |
The path to the new geometry with the combined data from the input geometries & destination geometry |
