losLabs PDF Library
« on: November 18, 2019, 03:20:24 am »
Has anyone had experience with losLab PDF Library?  This is a library of PDF routines written in Delphi.  They claim that it can be fairly easily ported to Lazarus.  I am interested in this for several reasons:  1)  It is being actively supported.  2)  It can rapidly convert PDF files to text files.  3) My expectation is that it will be kept up to date.

The URL for this product is:

Their website doesn't mention it supports Lazarus.

Have you tried this:

Thank you for the suggestions.  The problem with those suggestions is that these PDF libraries create and edit PDF documents.  My interpretation of them is that they are not capable of reading existing PDF documents and converting the contents to human readable text.  Is this interpretation correct?

My understanding is that the losLab PDF library is written in Delphi's pascal and would have to be converted to Lazarus.

Well, this seems to be closed-source software. You must contact the authors of this library whether they can do the adaption to Lazarus (it would be a good marketing argument to support Lazarus!), or you must do it yourself after you bought the sources. Nobody can help you here.

What about fpc-pdf, which is - certainly in 3.2.0+ excellent and comes as standard.
also related to equus asinus.

fcl-pdf is also write only.  He wants read-modify-write.
