When/if you are scanning paper images by using a scanner, your scanner's apparent default is to save scanned images to PDF files. In all probability, you can, and may want to, change the output of the scan so that it is not a PDF file, but, instead, is a graphics filie of one type or another, e.g., *.jpg (aka jpeg), *.bmp (aka Windows bitmap), or *.gif (aka Compuserve gif). Other graphic formats are also possible, but these 3 are the most common. *.bmp files render the highest quality, but are relatively large file sizes; *.jpg are more typical and they result in smaller file sizes, while still 16.7 million colors; *.gif files are better for text & line drawing and are 256 colors, which is not so good for "pictures".
PDF is not a graphic file format at all, but is the "Portable Document Format" which is proprietary to Adobe Acrobat. A PDF file certainly may include graphic image files, but in and of itself, it is not a "graphic" file, per se, even if the resulting PDF file happens to "contain" nothing but "graphic" files. Very often, PDF files contain both text and graphics. For example, some of the PDF files produced by Downtown Now include graphic files, as well as text. But, to "extract" the graphic images/files FROM the PDF document itself, I must open Adobe Acrobat (not the reader, the full Acrobat program), and export the graphic files contained in the document so that I have the native graphic files themselves. Doing that, I can then manipulate those files (resize, change graphic file format, crop, etc.).
I hope this makes sense. If so,
The 1st thing to do is to check your scanner's settings ... chances are, when you scan, you don't HAVE to convert the images to PDF, but that you have the capability of selecting different conversion options than scanning to PDF, e.g., to scan to a "bitmap" file (a generic term), such as (but not limited to) the graphic file formats I've mentioned above, such as *.bmp, *.jpg, or *.gif.
And, if you DO scan to PDF, and you want to extract the images in the PDF document to a true graphic file format, I'm pretty sure that you'd need some version of Adobe Acrobat (not Reader) to do that.
Before I go further, check your scanner's settings to see if you can save to something other than PDF files ... that's often a good choice, but it is not a good choice for what you're wanting to do in this instance ... just scan your paper pictures into a graphic file format.
I'll look for your reply and then reply again, if you want.
