Paragraph leading expression

[Filip Vandueren]

Hi Jamel, try this:

txt=text.sourceText;
fs= txt.style.fontSize * 1000/effect("boxWidth")("Slider");
ld = txt.style.leading * 1000/effect("boxWidth")("Slider");
style.setFontSize(fs).setAutoLeading(false).setLeading(ld);

Important: if you want to change leading or fontsize in the character palette, also first disable the sourceText expression!

you can do it all in code too like this for 60/90 size/leading:

txt=text.sourceText;
fs= 60 * 1000/effect("boxWidth")("Slider");
ld = 90 * 1000/effect("boxWidth")("Slider");
style.setFontSize(fs).setAutoLeading(false).setLeading(ld);

Here’s a small adjustment that will support auto leading:

txt=text.sourceText;
fs= txt.style.fontSize * 1000/effect("boxWidth")("Slider");
ld = (txt.style.autoLeading ? fs*1.2 : txt.style.leading * 1000/effect("boxWidth")("Slider"));
style.setFontSize(fs).setAutoLeading(false).setLeading(ld);

Hi Filip

Sorry for answering a little bit late, my machine is dead last week and i had to find a way to recover my files… long story…

i wanna thank you again and again… a lot of time

the code works fine, but when i try to link the source text to another text it doesn’t work, can you tell me why ? ( i just changed the first line of code )
THANK YOU FILIP

txt=thisComp.layer(“TEXT”).text.sourceText;

fs= txt.style.fontSize * 1000/effect(“boxWidth”)(“Slider”);

ld = (txt.style.autoLeading ? fs*1.2 : txt.style.leading * 1000/effect(“boxWidth”)(“Slider”));

style.setFontSize(fs).setAutoLeading(false).setLeading(ld);

Hi jamel, “style” is the current layer’s style, in your case it needs to be the other layer’s style.

so the final line should be:

txt.style.setFontSize(fs).setAutoLeading(false).setLeading(ld).setText(txt);

Hi Filip

Just a small question:
i want to get the right Height of the text, the problem that i don’t get the right one when i use sourceRectAtTime. for example: if the paragraph is 2 lines, even if i move a little bit the Solid to modify the bouding and the paragraph stays 2 lines, the Height changes, its supposed to stay the same value, unless the paragraph is 3 lines.

Hi Jamel,

The value is correct: it is the height of the sourceText. But you need to multiply a layer’s sourceRect height by scale[1]/100 to get the actual pixel-size of the layer.

And if the layer is parented, you also need to take into account the scale of parents etc.
