Read PDF Content in C#

Hi, I want to read PDF content in C#. I want to extract text, lines, and rectangles from PDF file which has schematic data as illustrated in one example below.

Can extraction from PDF be done? If yes, please suggest the library which can be used and purchased.

Thanks!

Aspose.PDF can extract text and images from the PDF. You can use it to read PDF Content in C#. However, functionality of extracting drawn images from PDF needs to be investigated. Do you want to extract only those images (lines and shapes) which has labels in the PDF?
