I am new in uipath, I am using PDF Activity to read Pdf text with Google OCR, because I want to get pdf text with images in it.
First I have used only Pdf Text,It worked perfectly.
Then I have used Pdf with OCR Then It is showing this Error.
But when I run it It is giving this error:-
"Google OCR : Error performing OCR: TessErrorLoadEngine"
Please help me to read the Pdf file.

I am creating onenote pages using the microsoft graph api. I try to display a pdf using the method found on the site https://learn.microsoft.com/en-us/graph/onenote-images-files#add-images-of-pdf-file-contents. However, it comes only as an attachment and does not render the pdf, like if I did a printout insertion in onenote. Has anyone encountered this and has anyone have some sample code if you did?
Thanks
The tag to embed the PDF as an image is <img data-render-src="name:FileBlock" /> (replace name:FileBlock with whatever the name of that form part is).
How do I embed a pdf using reStructured Text? With the following directive, I only get the first page.
.. image:: /pdfs/cv.pdf
For context, I'm trying to do this in a Pelican based blog.
A plugin for Pelican called pdf-img description says:
Searches for any tags within your article for which the source is a PostScript, EPS, or PDF file. It will produce a PNG preview of the file and this PNG will be displayed as the image. This preview will also act as a link to the original file. If the PDF/PS/EPS file is a multi-page document, then only the first page will be used for the preview.
That explains why you get those results.
I could find no plugin that "embeds a PDF" (by which I assume you want to embed a PDF viewer within your Pelican blog that would display the entire PDF, allowing the viewer to scroll through it in an iframe or something like that), but you can try searching for others.
I am trying to read a PDF as text, and I can write it back with junk in it, which is fine as I have a parser component to get the bits I need.
My question is how can I read specific parts of the PDF and ignore the rest?
If your PDF is well formatted, you can do it using text scraping, but that means you need to open the PDF file and it must be visible for Native Scraping to work

Here is my first time that I want to raise my issue here. As the title now I have a trouble with exporting a base64 image data to PNG, JPG, and PDF in GWT so I need your help from you. Let I give you an overview what I want to do:
Please have a look here: http://testingqr.appspot.com/ This is my app to generate a qrcode. After process of customization the Qrcode, I want to export the QR code in the canvas to png,jpg and pdf. To do that I will add 3 buttons are "Export to PDF" "Export to PNG" "Export to JPG" after press on each of these button, a Download Dialog will appear (Save as dialog) to let user choosing the location they want to save to and the extension of the file too (Such as C:\test.png)
I already use dataToURL function to get a base64. I used CanvasTo Image library from this link http://www.nihilogic.dk/labs/canvas2image/ But it will download the image from canvas with no Save as dialog and no extension in FF or chrome (IE does not support for HTML5 Canvas). So that I cant export PNG and JPG. This is my first problem.
The second problem is exporting PDF in GWT, I want to work with an open source library. I tried PDF Box http://pdfbox.apache.org/userguide/cookbook.html But now it just supports the JPG type. I want something that convert to PDF from base64. Do you have idea to help me do exporting to PDF process. What I want is after I press on "Export to PDF" button, a dialog will appear to let me save the QRcode in PDF file to my local location.
So thank you all for any help. Have a nice day.
