When I edit a PDF mapped from my website, the line height of the text change, move to top. I know the PDF edit tools and the mapping line height are different. My questions are
1- Can I set a fix or default line height for my Foxit reader test fields?
2- Can I know the line height of the text field? PS: the PDF is mapped with the java Itext7.
What do you mean by "line height", exactly? And Reader can't edit fields, only fill them in.
You're facing that effect because the font size 9.8 is too big to fully fit into the form fields. You'll have to set a smaller font size in Foxit or Acrobat Pro. In Acrobat Reader you can't do anything to fix this.
Make sense, can I know what is the min dimension for the font size Calibri 9.8?
A height around 5 mm (0.1969 in) I guess.
There is something weird, when I changed the field height to 5 mm, the text is fixed when I zoom 150% or 50% else the text is still moving!
