Load graphics with phpSpreedSheet - php

Question

I am using PhpSpreedSheet to load an excel, update it and save it again ... The problem I find is that it does not save it well for the graphics, and when you open the excel it tells you the typical thing that there has been a problem and "Do you want that we try to recover as much content as possible? " and remove the graphics.
Excel has completed validation and repair at the file level. Some parts of this book may have been repaired or discarded. Part removed: Part Properties of the document. (Drawing form) Part removed: Drawing form. Removed part: Drawing form.
$reader = IOFactory::createReader('Xlsx');
$reader->setIncludeCharts(true);
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($this->spreadsheet);
$writer->setIncludeCharts(true);

Answer 1

To include a drawing you should use something like this:
$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
$drawing->setName('Logo');
$drawing->setDescription('Logo');
$drawing->setPath('./images/officelogo.jpg');
$drawing->setCoordinates('B15');
$drawing->setHeight(36);
$drawing->setWorksheet($spreadsheet->getActiveSheet());
For reading out of all images you should use the code from the documentation:
$i = 0;
foreach ($spreadsheet->getActiveSheet()->getDrawingCollection() as $drawing) {
if ($drawing instanceof \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing) {
ob_start();
call_user_func(
$drawing->getRenderingFunction(),
$drawing->getImageResource()
);
$imageContents = ob_get_contents();
ob_end_clean();
switch ($drawing->getMimeType()) {
case \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_PNG :
$extension = 'png';
break;
case \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_GIF:
$extension = 'gif';
break;
case \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_JPEG :
$extension = 'jpg';
break;
}
} else {
$zipReader = fopen($drawing->getPath(),'r');
$imageContents = '';
while (!feof($zipReader)) {
$imageContents .= fread($zipReader,1024);
}
fclose($zipReader);
$extension = $drawing->getExtension();
}
$myFileName = '00_Image_'.++$i.'.'.$extension;
file_put_contents($myFileName,$imageContents);
}
