    • 4. About this presentation  The intro  Requirements  Creating and loading  Saving  Working with pages  Page sizes  Duplication and cloning  Colors & fonts  Text & image drawing  Styles  Advanced topics
    • 5. Zend_PDF: the intro  Create or load pdf files  Manipulate pages within documents, reorder, delete, and so on…  Drawing possibilities for shapes, lines, …)  Drawing of text using 14 built-in fonts or use own TrueType Fonts  Image drawing (JPG, PNG [Up to 8bit per channel+Alpha] and TIFF images are supported)
    • 6. Requirements  Zend_PDF is a component that can be found in the standard Zend library  Latest Zend library available from http://framework.zend.com/download/latest
    • 7. Folder structure
    • 8. How to integrate  Use the autoloader for automatic load of the module when needed (or load it yourself without ) : protected function _initAutoload() { $moduleLoader = new Zend_Application_Module_Autoloader( array( 'namespace' => ‘demo', 'basePath' => APPLICATION_PATH ) ); return $moduleLoader; }
    • 9. Creating and loading  One way to create a new pdf document:  Two ways to load an existing document:  Load it from a file:  Load it from a string: $pdf = new Zend_Pdf(); $pdf = Zend_Pdf::load($fileName); $pdf = Zend_Pdf::parse($pdfString);
    • 10. Saving  Save a pdf document as a file:  Update an existing file by using true as second parameter:  You can also render the pdf to a string (example for passing through http) $pdf->save(‘demo.pdf'); $pdf->save(‘demo.pdf‘, true); $pdfData = $pdf->render();
    • 11. Working with pages  Add a page to an existing file:  Remove a page from an existing file:  Reverse page order: $page = $pdf->newPage(Zend_Pdf_Page::SIZE_A4); $pdf->pages[] = $page; unset($pdf->pages[$id]); $pdf->pages = array_reverse($pdf->pages);
    • 12. Page sizes, some possibilities  Specify a specific size: Some other possibilities are:  Use x and y coords to define your page: $page = $pdf->newPage(Zend_Pdf_Page::SIZE_A4); $pdf->pages[] = $page; $page = $pdf->newPage(200, 400); $pdf->pages[] = $page; Zend_Pdf_Page::SIZE_A4_LANDSCAPE Zend_Pdf_Page::SIZE_LETTER Zend_Pdf_Page::SIZE_LETTER_LANDSCAPE
    • 13. Page sizes, some possibilities  Get the height and width from a pdf page: $page = $pdf->pages[$id]; $width = $page->getWidth(); $height = $page->getHeight();
    • 14. Duplicating pages  Duplicate a page from a pdf document to create pages faster  Duplicated pages share resources from the template page so you can only duplicate within the same file // Store template page in a separate variable $template = $pdf->pages[$templatePageIndex]; // Add new page $page1 = new Zend_Pdf_Page($template); $page1->drawText('Some text...', $x, $y); $pdf->pages[] = $page1;
    • 15. Cloning pages  Clone a page from any document. PDF resources are copied, so you are not bound to the same document. $page1 = clone $pdf1->pages[$templatePageIndex1]; $page2 = clone $pdf2->pages[$templatePageIndex2]; $page1->drawText('Some text...', $x, $y); $page2->drawText('Another text...', $x, $y); $pdf = new Zend_Pdf(); $pdf->pages[] = $page1; $pdf->pages[] = $page2;
    • 16. Colors  Zend_Pdf_Color supports grayscale, rgb and cmyk  Html style colors are also supported through Zend_Pdf_Color_Html // $grayLevel (float number). 0.0 (black) - 1.0 (white) $color1 = new Zend_Pdf_Color_GrayScale($grayLevel); // $r, $g, $b (float numbers). 0.0 (min intensity) - 1.0 (max intensity) $color2 = new Zend_Pdf_Color_Rgb($r, $g, $b); // $c, $m, $y, $k (float numbers). 0.0 (min intensity) - 1.0 (max intensity) $color3 = new Zend_Pdf_Color_Cmyk($c, $m, $y, $k); $color1 = new Zend_Pdf_Color_Html('#3366FF');
    • 17. Fonts at your disposal  Specify a font to use: Some other possibilities are: $page->setFont(Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA), 12); Zend_Pdf_Font::FONT_COURIER Zend_Pdf_Font::FONT_COURIER_BOLD Zend_Pdf_Font::FONT_COURIER_ITALIC Zend_Pdf_Font::FONT_COURIER_BOLD_ITALIC Zend_Pdf_Font::FONT_TIMES Zend_Pdf_Font::FONT_TIMES_BOLD Zend_Pdf_Font::FONT_TIMES_ITALIC Zend_Pdf_Font::FONT_TIMES_BOLD_ITALIC Zend_Pdf_Font::FONT_HELVETICA Zend_Pdf_Font::FONT_HELVETICA_BOLD Zend_Pdf_Font::FONT_HELVETICA_ITALIC Zend_Pdf_Font::FONT_HELVETICA_BOLD_ITALIC Zend_Pdf_Font::FONT_SYMBOL Zend_Pdf_Font::FONT_ZAPFDINGBATS
    • 18. Use your own fonts  Only truetype fonts can be used, create the font:  Then use the font on the page: $myFont = Zend_Pdf_Font::fontWithPath('/path/to/my/special/font__.TTF'); $page->setFont($myFont, 12);
    • 19. An error with a custom font?  Errors can arise with embedding the font into the file or compressing the font.  You can use the following options to handle these errors:  Zend_Pdf_Font::EMBED_DONT_EMBED Do not embed the font  Zend_Pdf_Font::EMBED_SUPPRESS_EMBED_EXCEPTION Do not throw the error  Zend_Pdf_Font::EMBED_DONT_COMPRESS Do not compress  You can combine the above options to match your specific solution.
    • 20. Adding text to the page  Function drawtext needs 3 parameters drawText($text, $x, $y);  Optional you can specify character encoding as fourth parameter: drawText($text, $x, $y, $charEncoding = ‘’);  Example: $page->drawText('Hello world!', 50, 600 );
    • 21. Adding shapes to the page  Different possibilities for shape drawing:  drawLine($x1, $y1, $x2, $y2)  drawRectangle($x1, $y1, $x2, $y2, $fillType = Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE)  drawRoundedRectangle($x1, $y1, $x2, $y2, $radius, $fillType = Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE)  drawPolygon($x, $y, $fillType = Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE, $fillMethod = Zend_Pdf_Page::FILL_METHOD_NON_ZERO_WINDING)  drawCircle($x, $y, $radius, $param4 = null, $param5 = null, $param6 = null)
    • 22. Adding images to the page  JPG, PNG and TIFF images are now supported  An example: // Load the image $image = Zend_Pdf_Image::imageWithPath(APPLICATION_FRONT . '/images/logo.tif'); // Draw image $page->drawImage($image, 40, 764, 240, 820); // -> $image, $left, $bottom, $right, $top
    • 23. An example in detail  Here’s a more complete example and the result: $pdf = new Zend_Pdf(); $page = $pdf->newPage(Zend_Pdf_Page::SIZE_A4); $pdf->pages[] = $page; $page->setFont(Zend_Pdf_Font::fontWithName( Zend_Pdf_Font::FONT_HELVETICA), 12); $page->drawText('Hello world!', 50, 600 ); $image = Zend_Pdf_Image::imageWithPath(APPLICATION_FRONT . '/images/logo.tif'); $page->drawImage($image, 40, 764, 240, 820); $page->drawLine(50, 755, 545, 755); $pdf->save('demo.pdf');
    • 24. The result
    • 25. Using styles  Create styles to combine your own specific layout of pdf in one place:  After creating the style, add some elements to your style  Apply the style $mystyle = new Zend_Pdf_Style(); $mystyle->setFont(Zend_Pdf_Font::fontWithName( Zend_Pdf_Font::FONT_HELVETICA), 12); $mystyle->Zend_Pdf_Color_Rgb(1, 1, 0)); $mystyle->setLineWidth(1); $page1->setStyle($mystyle);
    • 26. Document info  Add information to your document through the properties: $pdf = Zend_Pdf::load($pdfPath); echo $pdf->properties[‘Demo'] . "n"; echo $pdf->properties[‘Dennis'] . "n"; $pdf->properties['Title'] = ‘Demo'; $pdf->save($pdfPath);
    • 27. Advanced topics  Zend_Pdf_Resource_Extractor class for cloning pages and share resources through the different templates  Linear transformations, most of them are available as from ZF 1,8 (skew, scale, …)
    • 28. Summary  Zend_PDF has powerful capabilities  Combining the extended pdf class on framework.zend.com makes life a little easier
