The following table lists the properties of the Vision Sensor:
| Property | Description |
|---|---|
| Accuracy | Necessary accuracy for template matching (between 0 and 1). |
| Clickx | X coordinate of the click point. Can be either absolute (for example, 20) or relative (for example, 0.5 to click in the center of the element). |
| Clicky | The same as Clickx, but for the Y coordinate. |
| Content | Bitmap searched for with template matching (i.e. the template). |
| Excludetext | If "false", the template is searched for exactly as it is defined in "content". If "true", only the outer part of the template is searched for, i.e. ideally the margins, without the text that might be in it. |
| Borderbottom | The size of the bottom border (in pixels) when "excludetext" is set to "true. borderleft, borderright and bordertop are analogous to that. |
| Grayscale | Indicates that the search is done in gray-scale. But it has no function at the moment, because the search is always done in gray-scale. |
| Left | X coordinate of the element. Relevant if several identical looking elements are found - in this case the element with the most matching X coordinate is selected. |
| Top | The Y-coordinate, analogous to left. If both left and top are specified, the element with the lowest Euclidean distance to the coordinate is selected. |
| Index | : If several elements are found, the element is selected which, if you count the elements from top to bottom and then from left to right, is at the corresponding position. If both index and left/top are set, an element is only selected if the element at the corresponding position is also the next element at the specified position. |
| Count | The number of elements that look the same. Must match if no position is given but index is set. |
| Originalscale | The scaling of the element when indicating. Currently has no function, but should be used at some point to find scaled elements again, for example, if you use different DPI settings than for at the production as on the development client. |
| OCRengine | The ID of the OCR engine to be used. At the moment only Tesseract is used, always 0 is used. |
| OCRlangmodel | The language model for OCR (if omitted, the language model is automatically selected - unlike the OCR activities, this is not just the first one in the list, but depends on the system language). |
| Multiline | Specifies that the element contains multi-line text. This sets the corresponding page segmentation mode for Tesseract in GetValue (for example, in GetTextActivity) and then possibly returns better results. |
| Context | A bitmap to search for in addition to the template. Is also relevant if there are several elements that look the same - the element that is closest to the context will be used. |
| Contextlabel | If no context was set or the context was not found, OCR searches for the text specified here to find the element. The functionality is exactly the same as with context. Regular expressions may also be used in contextlabel. |
