read¶
Syntax: read(image name, filename, data type)
Reads an image or image sequence from disk. Determines type of file automatically.
Note
In Python/pi2py2, the image name parameter is not specified, and the function returns the newly created image read from the disk.
This command can be used in the distributed processing mode. Use distribute command to change processing mode from local to distributed.
Arguments¶
filename [input]¶
Data type: string
Name (and path) of file to read or a sequence definition. If a directory name is given, all files in the directory will be read. If the a file name is given, it can contain wildcards \(*\), \(?\) and \(@\). Wildcard \(*\) corresponds to any sequence of characters, wildcard \(?\) corresponds to any character, and wildcard \(@\) corresponds to sequence of numerical digits. For example, sequence containing files xyz_000.png, xyz_001.png, xyz_002.png, etc. could be read with template xyz_@.png.

Data type: string
Default value: “”
Data type of the image. Can be uint8, uint16, uint32, uint64, int8, int16, int32, int64, float32, or complex32. Specify empty value to infer data type from file content.
