UI Lua API import (WAR 1.4.8)

New page

{{LuaApi|group=DynamicImage}}
Returns whether a DynamicImage has a usable texture.

<pre>
hasTexture = DynamicImageHasTexture(imageName)
</pre>

== Arguments ==
;imageName : <code>string</code> – Name of a DynamicImage window.

== Returns ==
;hasTexture : <code>boolean</code> – <code>true</code> if the image has a texture.

== Details ==
* Once the image has loaded its texture, the result tells whether that load produced a texture.
* Before that, the client looks the image's texture name up and returns <code>true</code> if a texture with that name is found.
* Both error messages name <code>DynamicImageSetRotation</code> instead of <code>DynamicImageHasTexture</code>.

== Errors ==
* <code>Error in function call 'DynamicImageSetRotation': Window %s does not exist</code>
* <code>Error in function call 'DynamicImageSetRotation': Window %s is not a DynamicImage</code>

== Example ==
Placing text below an image only when the image has a texture, from <code>ea_tomeofknowledge/source/tomewindow_bestiary.lua</code>:
<pre>
WindowClearAnchors( "BestiarySpeciesInfoText1" )
if( DynamicImageHasTexture( "BestiarySpeciesInfoImage" ) ) then
WindowAddAnchor( "BestiarySpeciesInfoText1", "bottom", "BestiarySpeciesInfoImage", "top", 0, 10 )
else
WindowAddAnchor( "BestiarySpeciesInfoText1", "top", "BestiarySpeciesInfoImage", "top", 0, 0 )
end
</pre>
