phpexcel insert multiple images in merged cells - php

Question

Forgive my poor English,I'm a programmer from Asia.
I want to insert multiple images in merged cells,but all the images are overlapping.So I write code like this:
//merge cells
$column = 0;
$cell = $position[$column].$row;
$merge_str = $position[$column] . $row . ":" . $position[$column] . $last_row;
$objExcel->getActiveSheet()->mergeCells($merge_str);
$cell_value = '';
$objExcel->setExcelFontFormat($cell, $cell_value, $font_size, false, 'left', 'center');
$offSetY = 10;
//loop $export_data_item['images_path'] ，$image_nums is the mount of images
for($i=0;$i<$image_nums;$i++){
if(file_exists($export_data_item['images_path'][$i])){
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setPath($export_data_item['images_path'][$i]);
$objDrawing->setOffsetX(10);
$objDrawing->setOffsetY($offSetY);
$objDrawing->setRotation(15);
$objDrawing->setHeight($export_data_item['images'][$i]['height']);
$objDrawing->setWidth($export_data_item['images'][$i]['width']);
$objDrawing->setCoordinates($cell);
$objDrawing->setWorksheet($objExcel->getActiveSheet());
$offSetY = $export_data_item['images'][$i]['height'] + $offSetY + 10;
}
}
I hope use 'offsetY' to space every images in vertical direction,but all images squeezed together.I think the reason is that I use "$objDrawing->setCoordinates($cell);", all images only in the $cell position.
I want to set all images be arranged according to the sequence and interval.Someone can help me?

Answer 1

Reason is (according to this) that OffsetY is specific to the cell.
Unfortunately I can't think of a solution. Ask them maybe.

Answer 2

This function works for me. It returns an array with Coordinate and OffsetX from a desired Position X and row number.
Maybe someone helps.
function getCoordOffx($posX, $row) {//Parameters: (desired Position X, row number)
global $objPHPExcel;
$cpos=$widthpix=0;//Set to 0 Current position and width pixels
$col=1;//First column
$colname="A";//If posX=0 not enter in while, and assign colname=A
while ($posX>$cpos) {
$colname=chr(64+$col);//Convert column to Letter. chr(65)=A
$width=$objPHPExcel->getActiveSheet()->getColumnDimension($colname)->getWidth(); //Get width of Column
$font=$objPHPExcel->getActiveSheet()->getStyle($colname.$row)->getFont();//Get Font of column and row
$widthpix= PHPExcel_Shared_Drawing::cellDimensionToPixels($width,$font); // convert to pixels
$cpos+=$widthpix;//Add pixels of current column to cpos
$col++;//Next column
}
$offsX=(int)($posX-($cpos-$widthpix));//Offset is Desired Position X minus start of current column
return array($colname,$offsX);//Returns Column Name Letter (A or C or E...) and OffsetX
}
$coAndOf=getCoordOffx(195,3); //Desired Position X=195, row = 3
$colL=$coAndOf[0];
$offX=$coAndOf[1];
