Problem with HSLFTable row height

[Diogo Luzzardi de Carvalho <di...@gmail.com>]

Hi,

There is an strange problem happen to me when I use table.setRowHeight();

I'm doing the following code:

double x = 0d;
double y = 100d;
HSLFTable table = slide.createTable(1, 1);
HSLFTableCell cell = table.getCell(0, 0);

cell.setText("Some Dynamic unknown size text");

HSLFTextParagraph paragraph = cell.getTextParagraphs().get(0);
paragraph.getTextRuns().get(0).setFontSize(9);

table.setColumnWidth(0, 119);
table.setRowHeight(0, 20);

y += table.getRowHeight(0);
table.moveTo(x, y);

The strange is that the table.getRowHeight(0) is returning 27 as a result
and when I open the ppt file the table has 1.6cm of height. With this I
can't correct move the table to the position that I want. I also tried to
get the value for the y variable using table.getAnchor().getMaxY() but the
result is also 27.

Has I need to create several tables with different number of columns I need
to get the correct value to sum in the y variable to be able to set the
correct position for my tables.

Could any one give me the correct directions to solve my problem?

Best regards

the setRowHeight method can't be used to set a height less than necessary to display the cell text.
I've noticed that HSLF is scaling the given points to pixels, opposed to what is written in the javadocs.
Although I regard this as a bug, I'm not sure if I should silently change the implementation or
introduce another (named) method with the correct behavior.

if you need the height in centimeters you can use the following:
        double heightInPoints = table.getRowHeight(0);
        double heightInCm = heightInPoints * Units.EMU_PER_POINT / Units.EMU_PER_CENTIMETER;

> With this I can't correct move the table to the position that I want.
Depending on the text I get correct calculated bounding boxes for the cells.
Please describe a bit more, what you are trying to achieve with the row heights.

Best wishes,
