问题 After reading the Adobe PDF 1.7 (ISO 32000-1:2008) specification, I'm still having trouble understanding how to properly create my transformation matrix.

Missing presentation forms (glyphs) of some arabic characters in Unicode

时光怂恿深爱的人放手 提交于 2021-02-05 11:14:08

Split PDF into chunks by page range in Php

爱⌒轻易说出口 提交于 2021-02-05 09:40:59
问题 so after browsing through many packages like TCPDF, FPDP, DOM2PDF and many other excellent php pdf packages, I couldn't find this feature in any packages where it allows to split the pdf file by page range. for example I want to split the pdf from page 20-100 or 30-50. or create a pdf from a pdf ranging from page 20-100. so is there any library that has this feature ? 回答1: PDFMerger has this functionality, and I personally enjoy its simplicity. $pdf = new PDFMerger; $pdf->addPDF('pdf1.pdf',
