Input
- Accuracy: Describes how much an image on the screen has to match the originally snipped image to be considered a match. Usually, 0.99 works well.
- Auto Invert: If checked, both the template and the image are inverted for certain matching methods to ensure reliability. Usually checked state works well.
- Image Representation: Defines on which image representation the search should be carried out. Usually GrayScale works well.
- Region Relative to Anchor: After finding the snippet image on the screen, this region - relative to the found image - is used for further actions, for example read out using OCR in case of the Get Text by Anchor activity.
- Search Region: The display region in pixels where the image is searched in. When empty the whole virtual screen including all monitors is used.
- Template Matching Method: Gets or sets the similarity measure. Usually, CcoeffNormed works fine. See the section on template matching methods within the Hyland RPA Designer documentation for more information.
Output
- Text: Output variable of the found text by ocr.
- Words: Output of a list with all found words.
