How to fit string in rectangle in OnRender() method?

[fx.practic]

Hello.

Is there a way to render string, using max height and max width, instead of text size?


There is a way to create TextLayout, and then measure height and width of string.
I need to perform a reversed task: set height and width of exact string, and then get size to use it in DrawText() or DrawTextLayout();

Is it possible?

Hello fx.practic,

You are wanting to use the width and height of a rectangle and convert this to a font size (or use this to choose a font size)?

I'm not aware of a SharpDX method that does this.

I think you are going to have to create some custom math / algorithm to convert this.
You might trying try using the length x width of rectangle to get the area, and then look at the width and height of the font from the text layout and see if there is a common ration at different sizes.

I was looking at the WPF FontSizeConverter, but I'm not certain this will suit your purposes.

This thread will remain open for any community members that may know of a method that exists for this that I am not aware of.

Thank you, Chelsea.
I will explore FontSizeConverter class and put results here.

My current solution that I consider as ugly is to re-create TextLayout in a loop with smaller and smaller font size until it fit my rectangle.
