Getting the width and height of a text strip

[bertieb]

I am in the process of doing some very similar. I was pointed at the blf module and in particular at blf.dimensions by @testure:

Is there a way to determine the size of a text sequence?

However, I face the problem of not being able to determine the fontid of the text strip’s font:

Getting a font from fontid, or fontid from VectorFont / TextSequence?

Context: https://blenderartists.org/t/is-there-a-way-to-determine-the-size-of-a-text-sequence/1453006/4 I am looking for a way get the size of a text strip. In the BA thread above, @testure kindly pointed me at blf.dimensions, which works but requires a fontid. Since I have not loaded the font myself via blf, I do not have a fontid†. The suggestion was to add 3 to the index of the font in bpy.data.fonts, but I found that in my case the offset is bigger (24-26) and not consistent even within t…

What I want to do works great if I figure out the fontid manually, or guess at the offset. If you’re doing this only for yourself and not looking for a generic solution you can use this method (blf.size() followed by blf.dimensions()) for the font you are using for your subtitles. Hope this keeps you moving!
