As we discussed below, we would like you to develop a custom version of PDF Image Extractor which has a new command-line option to only extract images that do not have underlying text.
We have created a new version of pdf2img.exe to you, please download the new version from following URL,
The new version of pdf2img.exe does support -checkhiddentext parameter, you can use this parameter to extract images from PDF pages which not contain hidden text contents, for example,
Pdf2img.exe -$ "XXXXXXXXXXXX" -checkhiddentext C:\test.pdf C:\out.tif
"XXXXXXXXXXXX" is your license key, you can use this license key to remove demo watermark from output image files.
If you encounter any problem with this version or this parameter, please feel free to let us know, we are glad to assist you asap.
Thanks. We'll start testing soon.
