Thank Brad. I don't want to save images into files and then read files into memory.
The disk IO expense is high. So what's the utility from another application can do this job? Wish your advice.
Thank you!

<pre wrap="">This should have gone to a mailing list.
How are you possibly going to use the utility from another application and
copy to memory without making any code changes?

Hi, all:<br>
In web search engine, I want to support the pdf snapshot. So I
want to convert pdf files to images and save the images in a
database. I don't want to change the poppler code.<br>
Because that's not<font color="#ffcc66"> <span style="color:
rgb(68, 68, 68); font-family:
Verdana,Geneva,Arial,Helvetica,sans-serif; font-size: 14px;
font-style: normal; font-variant: normal; font-weight: bold;
letter-spacing: normal; line-height: 21px; orphans: 2;
text-align: left; text-indent: 0px; text-transform: none;
white-space: normal; widows: 2; word-spacing: 0px; display:
inline ! important; float: none;">convenient for upgrade the
poppler's code.</span></font> <br>
<br>
Thank you for your precious advices.<br>

<pre wrap="">I'm sure that is possible, but you'd need to make some code changes (and
consider whether an arbitrary binary blob, containing nulls, is really a good
idea in a std::string). The code changes should basically be taking the
existing output writer and copying in to a memory location instead. I don't
see you'd need to make any real popper changes. How you integrate that depends
on the application you're trying to create.
What is the end-use for this?
Brad
