Extracting and Searching Text

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Hi,

your question might be answered in a few posts at here. You should try the different options for ExtractPageFileText and play with them using a smaller PDF, to get some feeling. After this, it is easier to understand the problems around searching and adding text.

Please keep in mind, that a PDF is no document like word works with. It is for example a lot of work to insert a forgotten letter in a word, because all things, which may surround this word will not automatically change their own position. It is more like a picture (because a PDF describes a layout) which want to paint on later. 

Your question about blank lines shows in a wrong direction. You want to hold a place free. Ok, but for this is it will be enough, to put the next line more down.

Try a look into the PDF-specification from Adobe. Read about operators and text. Then you get an idea what all QuickPDF does for you and where are limits.

Good luck,
Werner

	I am using vb.net and are having some issue. Is it possible to search through a pdf for a string and return the values in the next row at specific character locations? is it possible to extract a PDF to text without it inserting blank lines where they would normally not be? i am looking for some examples if anyone could help it would be appreciated. Thanks
