Re: [osg-users] Issue with texturing label

Hi Robert,

The issue was with our image loader and not with the GUI itself. Once we
managed to track that down the fix was pretty straight forward. Thanks.

Hi Sam,


It's hard to know what is wrong without more concrete information on
exactly how you are setting things up, so I can only provide general
thoughts.

First up, could well be blending as you suspect.  Have a look at making
sure the texture quad doesn't have blending enabled somewhere, or blending
being enabled further up in the scene graph which is overriding the local
state.   Another issue might be texture clamping of the texture.  Clamp to
border, or setting the border colour of the texture.  This is just
clutching at straws though, really don't know enough about the specifics of
how you are doing things to know what it might be.

Robert.

One can normally just attach a .cpp file to post.

Hi Robert,

What is the best way to send a small example through the mailing list?
Pastebin? Inline? I'm not very familiar with how the mailing lists formats.

Thanks, Sam

[osg-users] Issue with texturing label

[sam]

Hi All,

I'm struggling with finding out why I have some discrepancy between my
texture and what my osg is drawing. I have setup a label and put a texture
against it as follows:

[image: Inline image 1]

But unfortunately I get that thin white bar at the bottom of the label. It
seems to change color based on what is below it. I have tried to turn off
blending and change the blend function but no luck thus far. Any help would
be greatly appreciated. Here is the original texture image:

Thanks, Sam
