A Get number building block gets a number on the whole screen or part of the screen. Formatting and filtering rules can be applied so that for instance only numbers which are formatted as “Price: [NUMBER] USD” and which are less than or equal to 1,500 are retrieved. See the Use Numbers and Variables and Capture text on screen lessons for examples of how this works.
Fully expanded, the Get number block shows the following properties:
-1.png?width=327&height=803&name=MicrosoftTeams-image%20(11)-1.png)
The green input connector in the header is used to trigger the block to start executing.
The green output connector in the header triggers when the number has been retrieved. If “All occurrences” of the “Use occur.” property is selected (see below), this output connector triggers on each iteration until all occurrences are iterated through.
The title of the block (“Get number”) can be changed by double-clicking on it and typing in a new title.
An area of the screen where the number will be searched for in X, Y, Width, Height coordinates, starting with the upper-leftmost pixel. The top-left corner of the screen is position 0, 0. If no area is defined, the entire screen is searched.
It’s possible to enter the area values manually, but the area can also be captured by right-clicking the property and selecting “Capture area”.
Click the expander button to work with the area’s position and size and their nested sub-properties separately.
The number that was retrieved from the screen, subject to the optional formatting and filtering settings (see below).
This green output connector triggers if a number is not found before the timeout, subject to the optional formatting and filtering settings (see below). This is typically used to branch execution flow or to explicitly fail a case by linking it to a Fail block.
The screen position where the number was found in X, Y coordinates. The top-left corner of the screen is position 0, 0.
Note that this position is the middle of the number retrieved, not the upper-leftmost pixel of the text.
Click the expander button to work with the X and Y coordinates separately.
The screen area where the number was found in X, Y, Width, Height coordinates, starting with the upper-leftmost pixel. The top-left corner of the screen is position 0, 0.
Click the expander button to work with the area’s position and size and their nested sub-properties separately.
Define a format that the number must meet to be retrieved. For instance, by defining “Price: [NUMBER] USD” only numbers inside text such as “Price: 123.00 USD” will be retrieved.
Define the character used to separate 1000s in the number. The default value will be that set on Studio’s regional settings in Windows — typically “,” or “.”.
Define the character used to separate decimals in the number. The default value will be that set on Studio’s regional settings in Windows — typically “,” or “.”.
Select whether the number recognition should be case sensitive. By default, it is case insensitive.
User can select LEAPWORK OCR text recognition engine like OCR 1.0 and OCR 2.0 or user can opt for 'ABBYY' as text recognition engine.
User can opt for "Full mode" or "Fast Speed" OCR mode.
Full mode: In full mode our OCR perform four recognition tries in parallel using two different modes i.e. two in normal and two in inverted colors.
Fast Speed: In fast mode our OCR perform two recognition tries in parallel one in normal and other in inverted colors.
OCR precision sets the accuracy of the OCR results on a character level. This means, a higher OCR precision level requires a higher confidence in the OCR engine before a certain character is matched.
With a high precision you can be very confident that the characters found are the correct characters.
On the other side a high precision can result in that some characters are not found. Setting a lower precision means that in general more characters are found, but the assurance that it’s the right characters is lower than with a high precision. So, the right setting is a balance between finding all the right characters and not include too much that ruins the result, and will depends on the font, colors, background, size of the text.
Precision Levels are:
Zero will return everything what was recognized by OCR and 100 will return the best possible recognized result.
In case the built-in OCR engine in LEAPWORK is not matching the requirements, it is possible to change the engine to ABBYY. ABBYY is the world leading vendor of OCR engines and perform second-to-one when it comes to OCR. Contact our [Customer Success, link to chat page] team to get started with ABBYY.
Check this checkbox if the number is placed on top of a textured background or is close to a visual border element. This instructs the text recognition engine to use a special mode to compensate for such backgrounds and borders.
It should be noted that no text recognition engine is perfect. If you experience problems with text recognition, try zooming in on the content. Larger letters are typically easier to recognize.
Define a filter that the number must meet to be retrieved. For instance, only retrieve numbers that are “Greater than” 100.
The value used by the filter.
Select which occurrence of the number on screen to use, if more than one is found.
Select “All” to iterate through all of the occurrences. By selecting “All”, the sub-properties Current index and Completed are shown (see below).
The current index when iterating through all occurrences of the number on screen. For instance, if three occurrences are found, this property will contain 1 for the first one, then 2 for the second and finally 3 for the last one.
This green output connector triggers when the iteration of all occurrences are completed.
If the 'Default Timeout' property checkbox is not selected, then the timeout value is 20 seconds. If the 'Default Timeout' property checkbox is selected, then the 'Default timeout' value selected in the flow settings will be applicable.
The maximum time spent searching for the number before giving up and triggering “Not found” (see above).
The default value is 20 seconds.
Note: All cases have a “global timeout” that can be configured in the “Settings” panel. This is unrelated to the timeout of a single building block. However, a running case will automatically be cancelled if it runs for longer than the global timeout.
When a value other than “None” is selected, the building block will use scrolling when searching for the number. This can be useful when searching in scrollable content such as web pages and documents.
The maximum number of times to perform a scroll before giving up searching for the number.
The amount of scrolling that will be performed on each scroll repeat.
The delay in seconds between each of the scroll amounts.
Delay the search for number until there has been no movement on the screen for a specific period of time — for instance 2 seconds.
This is useful when waiting for a screen update to occur, for instance a page loading in a browser window. Regardless of this checkbox, the search will occur after waiting a maximum of 30 seconds.
The number of seconds the screen must have seen no movement before proceeding.
