I have a list of images that I am currently looping through.
Is it possible to have a command where I can put in the location of text that I am trying to extract or show it with something like Citrix Scrape on what data I want to take out?
The Get OCR Text action requires you to provide a UI element. One simple option is to loop over all images, then open them in an image viewer of your choice, and then use the Text -> Scrape Relative to extract your invoice number into a variable.
You can use the Desktop Recorder for all actions mentioned above. Note that you will have to adjust the Selectors, as the Recorder usually considers the text the application title as well (which will often include the document's name, and that's not what you want as all your invoices will have different names). You can just open another invoice in your application, then open the Selector and Attach to Live Element to let UiPath work out the Selector for you - which works just fine in most cases.
Depicted below: a sample sequence created with the Desktop Recorder. Here I just read the invoice number with OCR, and I use IrfanView to display them. Of course you may want to increase the zoom level to enhance your OCR results in a real-world scenario.

I have more than 100 images (svg) and I want to create PDF to them with their names for example in the future the user can access this PDF to check the icon and what is the name of the icon.
is there is any possible way to automate this process?
I try to create this word manually but this process is taking to much time
I am using UiPath and am currently trying to extract data from a screen that looks like this:
When I use the Screen Scraping tool, I am able to get the data:
But when I add Get Full Text activity into my sequence and select the same region, the output to the variable is always blank.
Am I missing something here?
In the screen scraping tool the scraping method you are using is native, Whereas you are using Get Full Text activity which is equivalent forfull-text screen scraping method to retrieve the same in UIPath studio.
So try to use Get Visible Text activity (Equivalent to native screen scraping method).
I hope you know there are 3 scraping methods as below
Full-Text (Equivalent to Get full text activity)
Native (Equivalent to Get visible text activity)
OCR (Equivalent to Get OCR text activity)

Given a rectangle that represents an area on a Windows screen that contains text, what is the best way to extract the text?
I know that it is possible using OCR, but even after significant pre processing, the quality is really poor.
Getting the Window Text using Win32 API does not always work as well.
Assuming that the text was rendered using a font, is it possible to get it from there?
Any directions would be extremely helpful. Thanks!
Given a rectangle that represents an area on window screen, the best way to extract text is indeed OCR. Use a better OCR library like this one from Microsoft.
The reason getting the window text using Win32 API does not work well is because there may be multiple windows in that rectangle. You will have to find out what all windows the rectangle contains and send a message to get the text for each window. It is not impossible but difficult to do and even if you manage to do that, you will run into issues of text alignment, etc. OCR is your best option.
It does seem possible without using OCR, as NirSoft SysExporter can do this:
https://www.nirsoft.net/utils/sysexp.html
This may be suitable for programmatic use as it can be run from a command line:
Starting from version 1.70, you can export the content of Windows
control from command-line, without displaying any user interface.
You may not be able to target it at a specific rectangle on the screen, but maybe the same result could be achieved by first scraping everything followed by some post-processing.
Further basic info:
SysExporter utility allows you to grab the data stored in standard
list-views, tree-views, list boxes, combo boxes, text-boxes, and
WebBrowser/HTML controls from almost any application running on your
system, and export it to text, HTML or XML file.
...
Known Limitations
SysExporter can export data from most combo boxes, list boxes,
tree-view, and list-view controls, but not from all of them. There are
some applications that use these controls to display data, but the
data itself is not actually stored in the control, but in another
location in the computer's memory. In such cases, SysExporter won't be
able to export the data.
Personally I've used it to grab text from what look like label controls.
Does someone knows how to display multiple images using ActiViz or VTK?
I have a RenderWindowControl, I would like to either display all the images like in a list in there or add multiple RenderWindowControls to display the multiple images..
Thanks!
You have some choices, for the task of visualize multiple images. I hope that at least one of them represents what you want to achieve:
1- Using multiple render windows. Basically, the example provided in the link creates an array of vtkRenderWindowInteractor objects, so that you can visualize multiple images.
2 - Using a single render window with viewports. The render window is splitted into viewports (renderer->SetViewport is the key, here), so that you can visualize n images at a time, where n is the number of viewports.
3 - Using the "slices" approach (the example works on DICOM files). This implements the "list" behaviour, as you said in your question. Basically, you visualize an image at a time, but you can navigate through them simply by pressing the arrow keys. The example derives the vtkInteractorStyleImage class to catch the events regarding key pressures.
Hi every One See the Below Image
in this Screen that 3 Blocks are images and i am trying to Bind some text to that Text Block and display with some time intervals with Live tile Look and feels. Can any One Sugest How can i do this
If you want to mimic Live Tiles, I suggest that you take a look at The Windows Phone Toolkit. It contains the HubTile control which is live and is probably the thing you are looking for.
If not, you have the source code and you can check how they did it. This way you can replicate the behavior and then customize it.
