Hi,
I'm setting the LabelText for a line layer:
TIELineLayer(Layers[idx1]).LabelText:= 'My label text'
TIELineLayer(Layers[idx1]).LabelPosition:= ielpAbove;
TIELineLayer(Layers[idx1]).TextOverflow:= ieoShrink;
ImageEnView.Update;

But after that,
only the first part of label is shown (ex. "My la"),
the text appear truncated.
I've tryed to use lockupdate/unlockupdate lockpaint/unlockpaint,
but always same issue,
i'm unable to set a label text with more that 5-6 characters.

If I add some fake text suffix, example
TIELineLayer(Layers[idx1]).LabelText:= 'My label text' + '. .'

The first part ('My label text') is shown.

Hi Claudio

Is this in 9.0.0? I cannot reproduce that using the following, can you give me more information?



ImageEnView1.LayersAdd( Point( 100, 100), Point( 200, 200 ));
TIELineLayer(ImageEnView1.CurrentLayer).LabelText:= 'My label text';
TIELineLayer(ImageEnView1.CurrentLayer).LabelPosition:= ielpAbove;
TIELineLayer(ImageEnView1.CurrentLayer).TextOverflow:= ieoShrink;
TIELineLayer(ImageEnView1.CurrentLayer).LabelFont.Size := 30;
ImageEnView1.Update;

Hi,
yes, I'm using latest version,
try with an inclined line,
with horiz or vert line it's ok.
I think that the problem is that the label goes wordwrap,
and text is not resized to fit.

Sorry, I cannot reproduce that. Do you see it in any of our demos? If so, please give me the exact steps to take.

Hi,
I've made a lot of tests,
finally I've find the way to reproduce.
The trick is the zoom. If you set zoom to 50%, and you resize a LineLayer, label is not resized correctly.

Here a sample project (https://easyupload.io/daxvog).
1. Create a line layer
2. Set zoom to 50%
3. Resize line layer
