Hi! It's not possible to read barcodes from/in a pdf-document with QuickPDF. You can insert but not read. Perhaps you can do something with reading the content (GetPageContent) and textextraction 'cause barcodes mostly comes together with readable text below. Cheers, Ingo |

Thank you for quick response!Reading the barcodes from pictures is not a problem anymore, but i would like to ask how can i save a .pdf (preferably only an exact part of the page) to image(.bmp).Also if i have a pdf ,for example 5 pages long, how can save separately the last 2 pages? Thanks in advance:HBaloo  |

Hi!
You mst user RenderDocumentToFile
function TQuickPDF0712.RenderDocumentToFile(DPI, StartPage, EndPage,Options: Integer; const FileName: string): Integer;You can't obain a precise part of a page. Just save the whole page and use an Image Editor to Crop.
