What steps will reproduce the problem?
1. Use the funtion myPDF.writeText(lineHeight, theText); with an embedded font.
2. Tried font size a line height and also tried to calculate line height
constant to match a given font e.g for Arial var lineHeight = theSize * 4.305
seems to work
3. Same calculation does not work for different fonts so spacing appears
differently on different fonts when outputted on pdf than it was in Flash.
What is the expected output? What do you see instead?
Expect identical spacing for identical font size also tried calculating a
constant
What version of the product are you using? On what operating system?
0.1.5 RC, OSX apache
Please provide any additional information below.
I'm using alivepdf's function writeText with embedded fonts but I'm having real
trouble trying to get it to match the line height (or spacing between lines)
proportionately from the view port in flash to the final pdf.
So when I use
myPDF.writeText(lineHeight, theText);
I'm not sure how to calculate lineHeight based on the size of the original font
and then the size it will be outputted at. I think the issue might be that
there is spacing / leading around the top and bottom of the text that is
treated different in each font and is treated differently in Flash to Alive PDF.
The user has an interface they draw a design on and then I translate this
viewport to a pdf. I have the original font size in flash and then I am
enlarging this font size by the factor that the final pdf is larger the
original viewport when I set the font and this works for the font size on a
single line for instance:
var newFontSize=enlargeFactor*theSize
myPDF.setFont(myEmbeddedFont, newFontSize);
If I use a line height proportional to the font size I can get it pretty much
right for a given font by calculating a constant. I.e for Arial var lineHeight
= theSize * 4.305 seems to work. However this is a different constant for each
font so I need to try and work out the formula.
Can anyone help with this? Perhaps I can get information from the font somehow
or the EmbeddedFont object? To determine this total line height for each font
before writing?
Thanks so much,
Joe
