Basic| Module: | FoundationLite |
|---|
Simulates capturing a frame from a camera.
Applications
Can be used as EnumerateImages, but its state is global in a program - does not reset when some task is finished.
| Name | Type | Description | |
|---|---|---|---|
 |
inDirectory | Directory | Input directory |
|
inFileType | ImageFileFormat* | File format of the images |
|
inSortingOrder | FileSortingOrder | Sorting order |
|
inRepeat | Bool | Determines whether to repeat reading directory after reading all files |
|
inProcessSubdirectories | Bool | Flag indicating whether to load images from the subdirectories or not |
|
inInvert | Bool | Flag indicating whether to enumerate images backwards or not |
|
inLoadAlphaChannel | Bool | Flag indicating whether to load alpha channel of the image or not |
 |
outImage | Image | Output image |
|
outFilePath | File | Output file path |
|
outFileName | String | Output file name |
Description
This filter works similarly to EnumerateImages, but it behaves more like a camera: it preserves its state across the whole program.
For example, you can have two GrabImage_FromFiles filters in two different Task macrofilters. When execution of second Task starts, images loaded previously in the first Task are not loaded again.
Examples
Description of usage of this filter can be found in examples and tutorial: HMI Start Stop.
Complexity Level
This filter is available on Basic Complexity Level.
