Important Update
Learning a programming language to develop software is not the only option anymore. We are introducing ByteScout RPA Tools, a modern app builder that gives you the power to create.
With ByteScout RPA Tools, you can build a particular class application that can perform business automation tasks without human interaction required (aka “robot”).
Using pre-built templates allows you to develop a new app from start to finish with no more than four clicks. All robots created this way can be altered to accomplish your business goals.

Make Your Robots – Try RPA Tools
We offer this robot to show you how you can add a QR bar code and a string to an existing PDF document using RPA Tools.
To create this robot, you need to open the RPA Tools application on your computer and press the “Add Robot” button.
Then you can press the “Advanced: Add QR code and string to PDF file” button in the “Select Template” dialog window.
You can see the “Robot Info” informational dialog window. Please press the “OK” button.
Now you have the robot created and displayed in the Designer.
This robot is a combination of three previously presented robots: “2 Easy start: Create QR code“, “3 Easy start: Add image to PDF file“, and “4 Easy start: Add text to PDF file“.
The robot does its job in three small steps.
First, it creates a QR code and saves it to a temporary PNG file.
The “IN String” parameter defines the content of the QR bar code.
The “text” block with the “{temp}\QR.png” string defines the name of the temporary PNG output file. We used {temp} macro as a replacement for the path to the temporary folder.
Next, it adds a string to an input PDF file and saves the result to a temporary output PDF file.
Again, the “IN String” parameter defines the line which the robot adds to the PDF document. We used the same text (“Just a message”) as for the QR code creation.
The font size for the line is 14.
The robot adds the line to each page as we did not specify the “IN Pages numbers” parameter (default behavior). Please note that we still need a “text” block connected to this parameter.
The position for the line of text is “300, 300” counting from the top left corner of a page.
The “text” block with the “{temp}\temp.pdf” string defines the name of the temporary PNG output file.
And finally, the robot ads the image of the QR bar code from the temporary PNG file to the temporary PDF file. The final result goes to the Output folder.
We specified the page number for this block, and it is the first page (0-based numeration). If we wanted to add the same image to other pages, we could make a comma-separated list like “1, 2”.
The position on the page for the QR code is “300, 350” which is below the string.
The final result goes to “{myDocs}\ByteScout\RPA Tools\samples\TextImageToPdf\Output\sample1.pdf” where {myDocs} is a macro for the Documents folder on your computer.
(You can find all macros descriptions in a dialog window if you press the “Macros” button in the ByteScout RPA Tools Robot Designer.)
Third, there are some service blocks to show you the resulting file produced by this robot.
We used a blue “Special: Open Folder (Selected File)” block. It opens Windows Explorer so you can see the “Output” folder.
The commenting blocks are the grey “print” and “text” blocks.
They are disabled, which means that the robot is not going to execute them. The commenting blocks are here only for your attention.
Now, as you have this robot created and displayed in the Designer, you can save it and close the Designer window using the “Save and Close” button.
After saving, you can see the robot name in the “Robots” list of the RPA Tools application.
To run the robot, please press the “Run” button.
Here is the input file that we used for this robot.
Here is the final output file created by the robot.
You can see that the robot added a string “Just a message” to each of the two pages of the PDF document. Also, you can find a QR bar code on the first page.
