I have requirement of converting PDF pages to images. There is a background image with some text in my file, and when I save it as an image only the background image gets saved.
Is there any software available for the same so that complete page can be converted to an image?
You can use pdftoppm from the poppler-utils package to convert a PDF to a PNG:
pdftoppm input.pdf outputname -png
This will output each page in the PDF using the format outputname-01.png, with 01 being the index of the page.
pdftoppm input.pdf outputname -png -f {page} -singlefile
Change {page} to the page number. It's indexed at 1, so -f 1 would be the first page.
If you'd like to work on a range of pages, you can also specify a number for the flag -l (last page), so having -f 1 -l 30 would specify the pages from 1 to 30.
Note again that .png will be appended to outputname automatically, so there's no need to include the extension. Also, -singlefile removes the -01 suffix cited above, since the output is known to have only one file.
The default resolution for this command is 150 DPI. Increasing it will result in both a larger file size and more detail.
To increase the resolution of the converted PDF, add the options -rx {resolution} and -ry {resolution}. For example:
pdftoppm input.pdf outputname -png -rx 300 -ry 300
