Comment(by serveralex):

 To clearify the use case I'll explain why I need to set height/weight
 manually.
 Basically I have a very big raster table with square HxW raster blocks in
 WGS84 and one arcsec pixel scale that covers a big landscape. so basically
 i'm doing geostatistical interpolation of measuring samples with block
 kriging in realtime. that means i collect measuring samples and when a
 specific "new" limit is exceeded I'm interpolating the values for all
 raster blocks in that sector. The kriging has to be done in projected
 mode, so I transform the edge coordinates of the raster block to UTM
 projection and build a slightly bigger grid with square 25m pixels. Then I
 resample the resulting interpolated data to a WGS84 raster with the exact
 same extents as the original ones. But that won't work as the UTM raster
 extents are slightly bigger than the WGS84 ones which means the resulting
 raster won't be HxW in size any longer. So basically I have to set the
 height/weight parameters manually.
