Comment merge plusieurs files PDF en un seul PDF

Si je comprends bien la question, vous essayez d'append un tas de files PDF indépendants dans un seul file PDF.

J'ai utilisé le code ci-dessous pour append 1 file pdf à la fin d'un autre pour créer un file pdf.

 //NSSsortingng *documentsDirectory = [paths objectAtIndex:0]; NSSsortingng *cacheDir = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]; // File paths NSSsortingng *pdfPath1 = [[NSBundle mainBundle] pathForResource:@"pdf1" ofType:@"pdf"]; NSSsortingng *pdfPath2 = [cacheDir ssortingngByAppendingPathComponent:@"temp.pdf"]; NSSsortingng *pdfPathOutput = [cacheDir ssortingngByAppendingPathComponent:@"out.pdf"]; // File URLs - bridge casting for ARC CFURLRef pdfURL1 = (__bridge_retained CFURLRef)[[NSURL alloc] initFileURLWithPath:(NSSsortingng *)pdfPath1];//(CFURLRef) NSURL CFURLRef pdfURL2 = (__bridge_retained CFURLRef)[[NSURL alloc] initFileURLWithPath:(NSSsortingng *)pdfPath2];//(CFURLRef) CFURLRef pdfURLOutput =(__bridge_retained CFURLRef) [[NSURL alloc] initFileURLWithPath:(NSSsortingng *)pdfPathOutput];//(CFURLRef) // File references CGPDFDocumentRef pdfRef1 = CGPDFDocumentCreateWithURL((CFURLRef) pdfURL1); CGPDFDocumentRef pdfRef2 = CGPDFDocumentCreateWithURL((CFURLRef) pdfURL2); // Number of pages NSInteger numberOfPages1 = CGPDFDocumentGetNumberOfPages(pdfRef1); NSInteger numberOfPages2 = CGPDFDocumentGetNumberOfPages(pdfRef2); // Create the output context CGContextRef writeContext = CGPDFContextCreateWithURL(pdfURLOutput, NULL, NULL); // Loop variables CGPDFPageRef page; CGRect mediaBox; // Read the first PDF and generate the output pages NSLog(@"GENERATING PAGES FROM PDF 1 (%i)...", numberOfPages1); for (int i=1; i<=numberOfPages1; i++) { page = CGPDFDocumentGetPage(pdfRef1, i); mediaBox = CGPDFPageGetBoxRect(page, kCGPDFMediaBox); CGContextBeginPage(writeContext, &mediaBox); CGContextDrawPDFPage(writeContext, page); CGContextEndPage(writeContext); } // Read the second PDF and generate the output pages NSLog(@"GENERATING PAGES FROM PDF 2 (%i)...", numberOfPages2); for (int i=1; i<=numberOfPages2; i++) { page = CGPDFDocumentGetPage(pdfRef2, i); mediaBox = CGPDFPageGetBoxRect(page, kCGPDFMediaBox); CGContextBeginPage(writeContext, &mediaBox); CGContextDrawPDFPage(writeContext, page); CGContextEndPage(writeContext); } NSLog(@"DONE!"); // Finalize the output file CGPDFContextClose(writeContext); // Release from memory CFRelease(pdfURL1); CFRelease(pdfURL2); CFRelease(pdfURLOutput); CGPDFDocumentRelease(pdfRef1); CGPDFDocumentRelease(pdfRef2); CGContextRelease(writeContext); 

 $mergedPath = '/tmp/bulkinvoice_merge_'.$vendor_id.'_'.$randomno.'.pdf'; $filepath = 'http://xyz/'.$vendor_id.'/'.$shipmentId.'_invoice_shipment_label.pdf'; $current = file_get_contents($filepath); $tempPath = '/tmp/bulkinvoice_'.$vendor_id.'_'.$shipmentId.'.pdf'; chmod($tempPath, 777); file_put_contents($tempPath,$current); $pdf = Zend_Pdf::load($tempPath); foreach($pdf->pages as $page){ $pdfExtract = $ex->clonePage($page); $pdf2show->pages[] = $pdfExtract; } //$pdf2show->pages[] = $ex->clonePage($pdf->pages[0]); echo "\n [->]Added in merged PDF : ".$shipmentId; $pdf2show->save($mergedPath); unlink($tempPath);
