B4J Question Inaccurate Drawing of Text using BCTextEngine

[xulihang]

Using the example here: https://www.b4x.com/android/forum/t...-image-with-bctextengine.168974/#post-1035768

We can see the text (我爱我的祖国！) is being cut. I think this means inaccurate measuring of text?

 

[Erel]

Where is it cut?

 

[xulihang]

I increased the font size to 50. This looks good.

But it does not look good if the size is 15. See the bottom part of the text.

 

[Erel]

BBCodeView1.Text = $"[TextSize=15]我爱我的祖国！
我爱我的祖国！
我爱我的祖国！[/TextSize]"$

This is what I get:

Here is another example. It will be easier to notice the text being cut if I zoom in the text image.

 

[Erel]

This is what I get:

It might be a rounding error related to the monitor DPI setting.

What is the output of Log(TextEngine.mScale)?

Try to increase TextEngine.SpaceBetweenLines or MinGapBetweenLines.

 

[xulihang]

The scale is 100%.

If it only has one line, then SpaceBetweenLines will not help with it.
