Is it possible to convert Image pdf in PDFTables package - pdftables

I am trying to convert PDF using PDFtables package which is an image of text, that is when we open the PDF in a PDF viewer and we cannot select words or lines with the cursor.
Whether there is any solution for converting this type of file using PDFtables package??

No you cannot do this with PDFTables. You will need to run your PDF through an OCR converter first before running it through PDFTables.

Rust open image with other format than file extension

I am trying to open an image in my Rust program. The image is named foo.png, but it won't open the image with image::open("foo.png").
If I rename the file to foo.jpeg, I can open the image, so my guess is that the formatting and the file extension do not match.
My question is then. how do I open a file named foo.png, but decode it as a jpeg?
I have tried image::io::Reader, but I can't seem to make it work properly.
You can use the image::load() function, which lets you specify the format:
let image = image::load(BufReader::new(File::open("foo.png")?), ImageFormat::Jpeg)?;

Scanned Image/PDF to Searchable Image/PDF

Can anyone suggest me how to convert a scanned image into a searchable image or a scanned pdf to a searchable pdf ?
I have been stuck in this situation since quite a while now.
i have tried pdfocr application in ubuntu but no success.
Tesseract version 3.03 supports creation of searchable PDF from image. For PDF, you can use GhostScript to convert it to image before sending it to Tesseract.
https://github.com/tesseract-ocr/tesseract
Currently, there is no right way of doing this on Ubuntu. All OCR engines output plain text and there is no way to add that text as a hidden layer on PDF over the image text.
Option 1: Use gscan2pdf which will make you a searchable PDF, but the OCRed text is placed in the top-left corner of the page, is invisible and much too small.
Option 2: Use PDF X-Change Viewer which has an option to OCR and works correctly by adding a text layer over the scanned image which is in concordance with it. You'll have to run it in wine, because it is a Windows application.

How can I add an image to an existing PDF template page containing form fields?

I'm doing a document scanning project that involves inserting a scanned image into an existing PDF template page that contains form fields. I've used ImageMagick to take process the scan, and then append a raster image of the form template to the bottom, and convert that image into a PDF. However, forms and checkbox fields have to be added manually to the resulting PDF. Below is a sample of my ImageMagick command.
convert inputScan.jpg -resize 975x420 FormTemplate.png -append CombinedFile.pdf
Ideally, I would run a command that would take the JPG scan and the PDF template file containing fields, and output a PDF file with the scan at the top of a page and the field-containing template text below it. The closest thing I could find to a solution was here, but PHP can't be used on the computer in question.
Any help or suggestions are greatly appreciated!
