Hi! Is there any way (at least theoretically, using python) to export 16bit float image instead of typical 8bit png raster?


Right now I am using this to export:


mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
mxd.dataDrivenPages.currentPageID = pageNum
arcpy.mapping.ExportToPNG (mxd, r"D:\mosaicrasterdata\FinalExport" + str(mxd.dataDrivenPages.pageRow.Name) + ".png", df,10016,10016,1210, 100, True)
del mxd


but none of the exportToPNG or exportToTIFF has options to deal with 16bit or 32 bit files, selection is only limited to:


  • 24-BIT_TRUE_COLOR —24-bit true color
  • 8-BIT_PALETTE —8-bit palette
  • 8-BIT_GRAYSCALE —8-bit grayscale
  • 1-BIT_MONOCHROME_MASK —1-bit monochrome mask
  • 1-BIT_MONOCHROME_THRESHOLD —1-bit monochrome threshold


Maybe I can somehow obtain that layour image bit data manually and save it to file myself?
