Few days ago, I converted a lot of Complex Chinese PDF to JPEG,
the PDFs almost hang by the resource issue or bug, sometimes the main menu can not work, or can not switch to another page. So I converted it, but the JPEG files count, if many, in one folder still has resource problem. I use 1.6ver, the V1.7 is more unstable for this.
How I convert it, I have written down in
this , but it is too bad, you can not print the sample pdf file which you provide, Is it protected?
By the way, the drawback is
you cannot search in JPEG.
less DPI setting will result some Zigzag, if large DPI will limit the resource,too.
The advantage are
I put the Jpeg's filenames in page sequence, then you can reach by page index dialog or tag.
Good cropping save Zoom operation, if you use zoom operation the resource will hang, too.
Dilation Image Processing enhances the contrast of text.
page flipping speed is more quick.
and more you still can use stylus in JPEG.
