Implement search (probably on / key ;-) in pdf and djvu files. Hopefully, we can reuse some of highlighting code for it.

I hope to use / key too, but we don't have that in K3 ;P

BTW, the mupdf app included in mupdf has a nice example of an implementation of text search (including finding the coordinates). That's what I intend to use as blueprint for implementing the content-based functionality.

@houqp how hard would it be to implement getText for crengine?

houqp commented 12 years ago

@dpavlin , I think crengine already supports text searching, so it might be even easier to do the searching highlight task with its built in methods. We can pass all the searching and highlight jobs to the engine and simply output the render result.

The problem here is we need to get familiar with its API... And I am completely run out of free time here.

dpavlin commented 12 years ago

I added crengine search with #231, but we'll probably need to use mpdf API for search to gain more performance.

Good job dpavlin :)
