extraction - Automatic deletion of some pdf contents -

-

i've got extract specific data high number of .pdf files. problem first thing have convert .pdf .txt can find data i'm interested in. after conversion there's high amount of artefacts in .txt files ( page numbers, hyperlinks contents page, footers, headers etc. ). these .pdf files quite huge ones ( every single file transcription of 7-12 hours of people talking ) cannot afford deleting things manually ( i've got ~60 .pdf files ). question - know tool allows automatic deletion of such contents?

i'd glad hear every proposition improve work :) thanks!

Deploying Qt Application on Android is really slow? -

as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
