In iText, what is the minimum height of a
PdfPCell for which a given size of font text is visible?
I mean is there any ratio between
PdfPCell and font size?
I am making a PDF with pages of size A3, A4 and A5.
I need to know the relation between
Font size and
PdfPCell minimum height,
so that the text will be visible.
In iText 7 we can work with cells in composite mode only, so we can not work with leading and Ascender / Descender. These values depend on the elements which you add into the cell. But still you can set the padding:
So, if you want the cell to have a minimal size, you need to set the padding to 0, the leading to match the size of the font, and tell iText to use the ascender and descender value.
DISCLAIMER: in the past, we've received reports from customers that showed us that not all fonts contain the correct ascender and descender information. This needs to be fixed at the font level.
