This feature allows you to define an x and y-axes coordinate system for an image, and then fetch a specific partition of the image by specifying the length and index.
Parameters
This table provides the description and values for the parameters for the indexcrop operation.
| Parameter | Description | Value |
|---|---|---|
| X | Length of each image partition during horizontal cutting. Either the x or y parameter must be used. | [1, image width] |
| Y | Length of each image partition during vertical cutting. Either the x or y parameter must be used. | [1, image height] |
| i | Image partition selected after cutting. (The value 0 indicates the first partition.) | [0, maximum partition quantity). If the maximum partition quantity is exceeded, the system returns the source image. |
Caveats
If the specified index exceeds the cut range, the system returns the source image.
Example
Divide an image equally by 100 on the X-axis, and fetch the first partition.
