Assume having a TextureRect
with some texture and arbitrary properties regarding expand
and stretch_mode
.
How do you easily get the size at which the texture is actually displayed without manually handling every possible case of the stretch mode?
I know I can get:
TextureRect.rect_size
andrect_scale
(inherited fromControl
) for the bounding rectangleTextureRect.texture.get_size()
for the image size in pixels
I’m confused. Why is rect_size not enough?

TextureRect.rect_scale * TextureRect.texture.get_size()
Edit: yeah, I just realized, this solution was for the custom stretch mode I wrote which uses the scaling property.
Since, if you scale a TextureRect, using TextureRect.rect_size() will only return the set width and height but not the actual displayed size. To get around this, I had to get the scale property and the image texture’s size manually to get the actual displayed size. But I digress.

Hmm, what if the texture’s scale is 1 but expand is on?

rect_size
may be controlled from elsewhere (container, script) and may be larger than the texture.

expand
or stretch_mode
don’t affect the rect_scale
property, so this approach doesn’t work
