I'm not sure I understand this slightly vague description, can you please go more in detail of what the problem is?

For example, if a pdf file is converted from jpeg, and you wnat draw a rectangle and fill it with color(highlight it). But it's not supported in Okular.

Right, we can't hightlight text, because there is no text, nothing to fix here, you can draw a polygon or a line, but since there's no text you can't expect us to automagically find it.

This bug is asking about block highlighting for images. Why can't there be a marker that works everywhere?
Comment 5 Albert Astals Cid 2012-08-09 21:08:23 UTC 
What does "block highlighting for images" mean?
Comment 6 Helge Hielscher 2012-08-09 21:34:35 UTC 
I.e. draw a (yellow) rectangle over some scanned text. The rectangle could be multiplied with the image to give a highlighting effect.
Another possibility would be a highlighter with a configurable width, that is restrained to horizontal and vertical drawing (and thus is fast to use on scanned material.) Abusing the line feature (change width („size“ in the dialog) and opacity) is not practical, because it is too slow to use and changes the color of the black parts as well.

So what you want is https://bugs.kde.org/show_bug.cgi?id=159601
Comment 8 Helge Hielscher 2012-08-09 21:50:07 UTC 
Well if the review tools could be configured to mimic the functionality of an highlighter on scanned text, than this might be an usefull workaround.
Comment 9 Albert Astals Cid 2012-08-09 21:56:22 UTC 
Well, I'd add a comment there so if somewhen anyone implements the configurable review tools they let you configure one to mimic the highlighter
