Hi i want to work whit my raster via pixelBlock, but when i try define to my raster value of NoData nothing happen. (I want set NoData as -9999, but when i create array of pixels, minimum value is 0. Also when i save this raster there is no NoData values only 0). do anybody know where is a mistake? I used to create pixelblock like this in past and it was workong fine. thank a lot
Dim pBlock As IPixelBlock3
Dim pPoint As IPnt
Dim pRasPropsIn2 As IRasterProps
Dim pRaster As IRaster
Dim pSingArray As Single(,)
pRaster = pOutRasterArray(0) 'Array whit raster object
pRasPropsIn2 = CType(pRaster, IRasterProps)
pRasPropsIn2.NoDataValue = -9999
pPoint = New DblPnt
pPoint.SetCoords(10, 10)
pBlock = pRaster.CreatePixelBlock(pPoint)
pSingArray = CType(pBlock.PixelData(0), Single(,)) ' this array has nodata = 0
