Description: ------------ In Excel 2000 a bitmap is always scaled incorrectly if it is inserted via insertBitmap (and no scale/ position attributes), regardless where I put the image. The author of _positionImage in Worksheet.php notes that "the SDK incorrectly states that the height should be expressed as a percentage of 1024." thus uses for the height a value of only 256. I changed these values to 1024 which made the insert work correctly for me. Reproduce code: --------------- $file = "/path/to/file/bitmap.bmp"; $worksheet->insertBitmap(0, 0, $file);

The scaling is visibly off in Excel 2003, as well, but I didn't have much luck using a factor of 1024 instead of 256. If my calling code uses a scale of (1, 0.8) to mean (1, 1), I get acceptable results.
