Summary: rounding bugs in HSSFPicture.getPreferredSize
Product: POI
Version: 3.2-FINAL
Platform: PC
OS/Version: All
Status: NEW
Severity: normal

In HSSFPicture.getPreferredSize(). This line:
h += (1 - anchor.dy1/256)* getRowHeightInPixels(anchor.row1);
doesn't work right. It computes (1 - anchor.dy1/256) as an integer before
applying it as a fraction to getRowHeightInPixels. So you always get h
incremented by 1 full row height (anchor.dy/256 evaluates to 0). It works if I
change it to:
h += ((float)1 - (float)anchor.dy1/256)* getRowHeightInPixels(anchor.row1);
Same problem with the code to apply an initial x-offset to the image width:
//space in the leftmost cell
w += getColumnWidthInPixels(anchor.col1)*(1 - anchor.dx1/1024);
should be:
w += getColumnWidthInPixels(anchor.col1)*((float)1 - (float)anchor.dx1/1024);
