Problem

when i resize an image using size function, it gets me image having bad quality.
-------------------------------------------------
code
-------------------------------------------------
Set LEADRasterView1 = Server.CreateObject("LEADRasterView.LEADRasterView")
Set RasterIO = Server.CreateObject("LEADRasterIO.LEADRasterIO")
set RasterProc = Server.CreateObject("LEADRasterProcess.LEADRasterProcess")
RasterIO.Load LEADRasterView1.Raster, source_file, 0, 0, 1

X1=439
Y1=0
W=223
H=149

RasterProc.Trim LEADRasterView1.Raster, X1, Y1, W, H

target_width=124
target_height=83

RasterProc.Size LEADRasterView1.Raster, target_width, target_height, 0
call RasterIO.Save(LEADRasterView1.Raster, target2, 21, 0, 5, 0)

Attached is the result I got when I used the Size method call.  The last parameter I passed was 4, which means I want to do a bicubic resize.  Bicubic resize will give you the best quality.  So your method call should be like this:  RasterProc.Size LEADRasterView1.Raster,
target_width, target_height, 4
