  • Autoscale Text Box for two lines of text

    Posted by Martin Brunner on November 1, 2023 at 1:39 pm

    Hi

    I am trying to build an auto scaling text box for two lines. In the image attached I have two different text boxes for each line, but now I am trying to do the same for both of them (red rectangle) but can’t get a result. For the expressions used please refer to the attached image aswell.

    Would anyone have a solution? Thanks a lot in advance!

    Update:

    I found the following expressions which works fine for the text box to adapt to first line of text.

    margin = 30;
    t1=thisComp.layer(“textLayer”);
    s1=t1.sourceRectAtTime();
    t2=thisComp.layer(“textLayer 2”);
    s2=t2.sourceRectAtTime();
    l = t1.toComp([s1.left, s1.top])[0] – margin;
    r = t2.toComp([s2.left+s2.width, s1.top])[0] + margin;
    t = Math.min(t1.toComp([s1.left, s1.top])[1], t2.toComp([s2.left+s2.width, s2.top])[1]) – margin;
    b = Math.max(t1.toComp([s1.left, s1.top+s1.height])[1], t2.toComp([s2.left+s2.width, s2.top+s2.height])[1]) + margin;
    createPath( [fromComp([l,t]), fromComp([r,t]), fromComp([r,b]), fromComp([l,b])], [],[], true);

    So if I am assuming correctly I would have to replace the expression for r with an expression that looks at the width of both text layers? Would anyone know how to do that? THX

    yes, you would actually use the math expression to ask after efefcts to find the longer of the 2 and use that as the width, Ill post that expresssion shortly if someone doesnt beat me to it

    I think you just need a new variable,

    Math.max(l,r)

    this would take the longer of l and r

    Hi Adam

    Thanks! I tried but I am not sure if I interpreted it right. I applied the Math.max to the variabale r in the last bit of the expression, which doesn’t give me a solution…

    margin = 30;
    t1=thisComp.layer(“textLayer”);
    s1=t1.sourceRectAtTime();
    t2=thisComp.layer(“textLayer 2”);
    s2=t2.sourceRectAtTime();
    l = t1.toComp([s1.left, s1.top])[0] – margin;
    r = t2.toComp([s2.left+s2.width, s1.top])[0] + margin;
    t = Math.min(t1.toComp([s1.left, s1.top])[1], t2.toComp([s2.left+s2.width, s2.top])[1]) – margin;
    b = Math.max(t1.toComp([s1.left, s1.top+s1.height])[1], t2.toComp([s2.left+s2.width, s2.top+s2.height])[1]) + margin;
    createPath( [fromComp([l,t]), fromComp([Math.max(l,r),t]), fromComp([Math.max(l,r),b]), fromComp([l,b])], [],[], true);

    Did I miss something?

    I have a few minutes to take a look. where is this expression posted, in fact, it may be easier if you just post a reduced version of your project in here with no source files and Ill see if i can edit it to work

    ok there you go, there might be a way to make this more efficient but i was not prepared to do all that work right now, lol. point is, it does what you want now.
