<p>Sets the size of the tile cache on the plug-in side. This function
|

is similar to <a class="link" href="libgimp-gimptile.html#gimp-tile-cache-size" title="gimp_tile_cache_size ()"><code class="function">gimp_tile_cache_size()</code></a> but supports specifying the
|
||
number of tiles directly.</p>
|
||
<p>If your plug-in access pixels tile-by-tile, it doesn't need a tile
|
||
cache at all. If however the plug-in accesses drawable pixel data
|
||
row-by-row, it should set the tile cache large enough to hold the
|
||
number of tiles per row. Double this size if your plug-in uses
|
||
shadow tiles.</p>
