     Type:  enhancement     |      Status:  new          
 Priority:  medium          |   Milestone:  PostGIS 2.0.0
Component:  postgis raster  |     Version:  trunk        
 Keywords:                  |  
----------------------------+-----------------------------------------------
 To get a much better performance on every ST_Get function on the raster
 header:

 RASTER_convex_hull[[BR]
 RASTER_getSRID[[BR]
 RASTER_getWidth[[BR]
 RASTER_getHeight[[BR]
 RASTER_getNumBands[[BR]
 RASTER_getXScale[[BR]
 RASTER_getYScale[[BR]
 RASTER_setScale[[BR]
 RASTER_setScaleXY[[BR]
 RASTER_getXSkew[[BR]
 RASTER_getYSkew[[BR]
 RASTER_setSkew[[BR]
 RASTER_setSkewXY[[BR]
 RASTER_getXUpperLeft[[BR]
 RASTER_getYUpperLeft[[BR]
 RASTER_setUpperLeftXY

 See if it is possible to do the same for a requested band so we can
 improve the performance of every other functions.
