A way to set a texture widget to a specific area of a texture ressource?

[Duugu]

I could split the triangle into single lines and set a new texture for each single line. But this seems to be a big overkill.

The only thing I know that actually changes a wow texture is this function:
http://wowprogramming.com/docs/api/SetPortraitToTexture
But that function only make a square become a circle.

The other is for minimap objects only. (You could add a shape).

SetTexCoord will get you knowwhere.

The last and only cropping mechanism we have are scrollframes.

There's a texture:SetMask(texturePath) function, but I've never managed to get it to work with a custom mask.

Ah. Hey. Thanks.

You're right, it is strange. The only way I could produce visible results was with "Atlas" textures instead of "file" textures. And even they are ... totaly distorted crap.

The client states:

usage: SetMask("maskName")

Whatever maskName is, it seems to be different from a simple texture/texture path.

[e] On the other hand ... they are using it like

self.info.instanceButton.icon:SetMask("Interface\\CharacterFrame\\TempPortraitAlphaMask");

on

<Texture name="$parentHeroicIcon" file="Interface\EncounterJournal\UI-EJ-HeroicTextIcon" parentKey="heroicIcon" hidden="true">
    <Anchors>
        <Anchor point="BOTTOMRIGHT" x="-7" y="7"/>
    </Anchors>
</Texture>

Weird. TempPortraitAlphaMask could be a special kind of blp. Using an other alpha_depth or alpha_type or mipmaps than the usual blps.

Unfortunatly the clients says also

SetTexCoord(ULx, ULy, LLx, LLy, URx, URy, LRx, LRy)....Cannot set tex coords when texture has mask

Whatever, I need to set the coords for my triangle 'mask' dynamically. So, I don't see a way to use it at all.

Are you speaking of http://wowprogramming.com/docs/widge...SetMaskTexture ?
Hm. I could build my texture out of a lot of minimaps. Hm. Sounds strange. I'll dig deeper into that. Thanks.

Whatever you're thinking about doing isn't going to work, you can't have multiple minimaps on screen unless they are identical.

Not to mention that they're minimaps, they're not textures.

[Duugu]

Ok. I'll skip it. Thank's for saving me that time.

So the only remaining approach seems to be to build them line by line or to skip the textured polygon at all. :/ *sigh*

Still not sure what are you trying to do.

He deleted the picture from his first post for some reason, but he wants a way to show only a triangular (or possibly other polygonial) region of a texture, rather than a rectangular region.

[Duugu]

Doh, ja, sorry. I've overwritten my own post by clicking on Edit instead of Quote witout realizing it. *fp*

I'm trying to map a texture onto a meshed polygon. For that I need a way to render a triangle part of a texture.
Example:
