+TCPDI_CF
+=====
+
+Composer ready [TCPDI](https://github.com/cloudframework-io/tcpdi_cf) based on https://github.com/propa/tcpdi
+
+PDF importer for [TCPDF](http://www.tcpdf.org/), based on [FPDI](http://www.setasign.de/products/pdf-php-solutions/fpdi/).
+Requires [pauln/tcpdi_parser](https://github.com/pauln/tcpdi_parser) and [FPDF_TPL](http://www.setasign.de/products/pdf-php-solutions/fpdi/downloads/)
+which are included in the repository.
+
+Installation
+------------
+
+Link package in composer.json, e.g.
+
+```sh
+composer require https://github.com/cloudframework-io/tcpdi_cf
+```
+
+Usage
+-----
+
+Usage is essentially the same as FPDI, except importing TCPDI rather than FPDI.  It also has a "setSourceData()" function which accepts raw PDF data, for cases where the file does not reside on disk or is not readable by TCPDI.
+
+```php
+// Create new PDF document.
+include_once ($this->core->system->root_path.'/vendor/cloudframework-io/tcpdi_cf/tcpdi.php');
+$pdf = new TCPDI_CF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
+
+// Add a page from a PDF by file path.
+$pdf->AddPage();
+$pdf->setSourceFile('/path/to/file-to-import.pdf');
+$idx = $pdf->importPage(1);
+$pdf->useTemplate($idx);
+
+$pdfdata = file_get_contents('/path/to/other-file.pdf'); // Simulate only having raw data available.
+$pagecount = $pdf->setSourceData($pdfdata);
+for ($i = 1; $i <= $pagecount; $i++) {
+    $tplidx = $pdf->importPage($i);
+    $pdf->AddPage();
+    $pdf->useTemplate($tplidx);
+}
+
+// Create new PDF document.
+$pdf = new TCPDI(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
+
+// Add a page from a PDF by file path.
+$pdf->setSourceFile('/path/to/file-to-import.pdf');
+
+// Import the bleed box (default is crop box) for page 1.
+$tplidx = $pdf->importPage(1, '/BleedBox');
+$size = $pdf->getTemplatesize($tplidx);
+$orientation = ($size['w'] > $size['h']) ? 'L' : 'P';
+
+$pdf->AddPage($orientation);
+
+// Set page boxes from imported page 1.
+$pdf->setPageFormatFromTemplatePage(1, $orientation);
+
+// Import the content for page 1.
+$pdf->useTemplate($tplidx);
+
+// Import the annotations for page 1.
+$pdf->importAnnotations(1);
+```
+
