If you use PDFRead on that .pdf, it can then return a directory full of .png's that all have any excess white margins removed (and are optionally dilated/sharpened).

Give it a try and select .html as your out(put) format.

If you still wish to work on the images, and they all have the same margins, and if you use a variety of MS Windows, you could try Irfanview's batch options, which I believe include cropping.

I used to install Irfanview on pretty much any MS Windows machine I had, and work's, and on those of friends and family (after explaining, and being given permission). It was my default "image viewer" of choice.

Cheers,
Marc

I do the exact same thing. I'm also the "IT guy" at work and set irfanview as the default viewer and print program of (huge) .jpgs.

This especially comes in handy when my staff need to print emails with large embedded jpeg's and Outlook Express doesn't know how to shrink them to fit the printed page...

(Neither do MS paint or IE!!!)

Although my official role was "IT Project Manager", I was the unofficial "IT guy" for the office too. In that MS world, I'd rate Irfanview as one of the finest Windows-only apps out there. If it had Linux and OSX versions that didn't require emulators (or, in the case of WINE, "Not Emulators" ) it'd be one of the first pieces of software I'd have downloaded onto my lappy and iMac. Fast, small, efficient, sufficient, works.

Cheers,
Marc

The Gimp can "autocrop".

With ImageMagick I think you can use -trim or this script

Thanks a lot! Irfanview is so nice! I love its batch tools. ACDSEE finally retire from my computer.
I have some chinese PDF in ANSI(GB2312) code. I never can read it in dr1000. PDFRead's result basic just dark area. The only thing I can do is use acrobat to export it to png.

Well, in that case, DON'T use the .pdf with PDFRead, but instead the resulting .png's created by Acrobat.

Just use In(put) Format as imgdir (browse to your .png directory and double-click the first file) and Convert as before.

If the acrobat created .png's were of low quality, then turn off dilation by selecting the checkbox 'no dilation' so as to get a clearer image.

Hope this helps!

Yup. It works but I never can generate prc file. It always just popup %temp%\pdfreadxxx directory for me.
But I got the pictures anyway.
Thanks.

I still use ACDSee v1.0 as MY default .jpg viewer, especially when I just want to view one .jpg. It works just fine for me, but it's got some limitations, in which case then I just use irfanview.

For .prc output, did you install the updated NRhtml2mobi.zip?

Yes and no, in particular, it goes into the 'bin' directory inside the PDFRead install directory, which by default is C:\Program files\PDFRead\bin. It's the same directory as 'pdfread.exe', if that's what you meant!

You should get a message that you are overwriting the existing one (placed there by the PDFRead Installer and not the one you placed there before ).

That's odd. Were you trying to create the Out Format imp1 or imp2?

If not, perhaps you could install the eBook Publisher software (Download latest (free) version of eBook Publisher) as this was previously required to generate .prc until I revised it in v1.8.2 to use instead my modified version of MobiPerl's html2mobi.exe.

Can you post a screenshot of the PDFRead GUI screen you used to generate this? (on Windows, just 'alt-Print Scrn' and paste into MS Paint, save it and upload it here as an attachment.)

Do not know why.
