Is this happening with Excel2007 or Excel5 writer. Do you have some sample code? Also, is it happening with latest source code?

Thanks for koyama.
this happen is Excel5 writer
$objPHPExcel = PHPExcel_IOFactory::load("new_org.xls");   // excel load
$objPHPExcel->getActiveSheet()->getRowDimension('7')->setRowHeight(100);  // row height rise
$objPHPExcel->getActiveSheet()->setCellValue('D7',mb_convert_encoding($strHead,'utf-8','euc-kr'));    // $strHead is string
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');  // writer

I notice the squeezed image. The error happens with Excel5 writer when the image overlaps rows with AutoFit height (usually containing some wrapped text).

PHPExcel does unfortunately not have (true) support for "AutoFit Row Height". For example, sometimes you want a paragraph of text in a cell, and the height of the row should adapt. In this case you want "AutoFit Row Height" in Excel.

Technically, PHPExcel does not support this because it is not able to calculate AutoFit row heights. In some cases this is a problem. For example there is a problem calculating (2-anchor) image position properties in Excel5 writer when the image overlaps an AutoFit row height.


There is currently no 100% satisfactory workaround. Some possibilities for you:

  1. Think about if it is possible to switch to Excel2007 writer? This writer does not have the problem.
  2. Set an explicit row height (to some suitable value) for the rows which the image overlaps. This will always fix the problem with the squeezed image. This is not autoFit, but sometimes it may be ok anyway.
