I am converting PDF to image using GhostScript. The problem i am facing is when pdf has links then i need to have those clickable links in converted image as well. How could i achieve this.
How do you expect an image format to have 'clickable links' ? What image format do you think has the ability to click on links ?

I would like to add text to an image using Images in julia.
I googled but results are not much helpful in this regard!
Please guide me adding text at specified co-ordintes to an image using Images in julia.
I am not aware of a solution using only Images, but you can do something like this with Plots and Images
using Plots, Images
img = load("test.png")
plot(img)
annotate!(1.,1.,text("test",20))
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.

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.
I use ITextSharp to print a PDF document. I put a logo (logo of Microsoft as example) on document and it is described perfectly in PDF file.
But after printing this PDF, I get gray dots accross logo on paper.
I use a PNG image with transparent background, and my logo is in high resolution as Microsoft logo. Please help how I can solve this issue?
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!
Is it possible to generate thumbnail images from PDF files using iText?
No. iText will not rasterize PDF at any resolution.
