I’m&nbsp;having&nbsp;an&nbsp;issue&nbsp;getting&nbsp;geotiffs&nbsp;with&nbsp;rotation&nbsp;being&nbsp;displayed.&nbsp;I’ve&nbsp;tried&nbsp;2&nbsp;cases:  
  
  
  
1)&nbsp;A&nbsp;geotiff&nbsp;with&nbsp;a&nbsp;world&nbsp;file&nbsp;(.tfw).&nbsp;This&nbsp;has&nbsp;rotation&nbsp;parameters&nbsp;defined.&nbsp;The&nbsp;geotiff&nbsp;renders,&nbsp;but&nbsp;is&nbsp;not&nbsp;rotated.&nbsp;Using&nbsp;library.managed.  
  
  
  
2)&nbsp;A&nbsp;geotiff&nbsp;without&nbsp;world&nbsp;file.&nbsp;It&nbsp;has&nbsp;4&nbsp;sets&nbsp;of&nbsp;model&nbsp;tiepoints&nbsp;defined&nbsp;(one&nbsp;for&nbsp;each&nbsp;corner).&nbsp;This&nbsp;does&nbsp;not&nbsp;even&nbsp;render.&nbsp;Using&nbsp;library.unmanaged&nbsp;(crashes&nbsp;with&nbsp;managed).  
  
  
  
I&nbsp;can&nbsp;send&nbsp;the&nbsp;geotiffs&nbsp;if&nbsp;that&nbsp;will&nbsp;help.

It&nbsp;looks&nbsp;like&nbsp;you&nbsp;are&nbsp;rotating&nbsp;the&nbsp;map&nbsp;in&nbsp;the&nbsp;code&nbsp;snippet&nbsp;you&nbsp;gave&nbsp;me.&nbsp;I&nbsp;just&nbsp;want&nbsp;the&nbsp;geotiff&nbsp;to&nbsp;be&nbsp;displayed&nbsp;correctly&nbsp;based&nbsp;on&nbsp;the&nbsp;georeferenced&nbsp;metadata&nbsp;embedded&nbsp;in&nbsp;the&nbsp;geotiff.&nbsp;In&nbsp;the&nbsp;geotiff&nbsp;I&nbsp;attached,&nbsp;I&nbsp;have&nbsp;4&nbsp;corners&nbsp;defined&nbsp;(as&nbsp;control&nbsp;points).&nbsp;The&nbsp;4&nbsp;corners&nbsp;are&nbsp;such&nbsp;that&nbsp;the&nbsp;geotiff&nbsp;is&nbsp;slightly&nbsp;rotated.&nbsp;This&nbsp;geotiff&nbsp;correctly&nbsp;displays&nbsp;in&nbsp;the&nbsp;esri&nbsp;sdk&nbsp;that&nbsp;I’m&nbsp;evaluating.&nbsp;I’ve&nbsp;attached&nbsp;one.
