代码示例
ComputePansharpenWeights 示例 1（Python 窗口）
这是 ComputePansharpenWeights 工具的 Python 示例。
import arcpy
arcpy.management.ComputePansharpenWeights(
"c:/data/rgb.tif", "c:/data/image.tif", "3 2 1 4")
ComputePansharpenWeights 示例 2（独立脚本）
这是 ComputePansharpenWeights 工具的 Python 脚本示例。
#Run Compute Pan Sharpen Weights tool using the bands 4,3,2,1
import arcpy
InMSraster = "C:\\Landsat7\\L71046029_02920050705_MTL.txt\\Multispectral"
InPANraster = "C:\\Landsat7\\L71046029_02920050705_MTL.txt\\Panchromatic"
band_index = "3 2 1 5"
arcpy.management.ComputePansharpenWeights(InMSraster, InPANraster, band_index)
ComputePansharpenWeights 示例 3（工作流脚本）
这是在其它工具中使用 ComputePansharpenWeights 输出的 Python 脚本示例。
#Compute the pansharpening weights and use the results in the
#create pansharpening tool.
try:
import arcpy
InRGBraster = "C:\\temp\\rgb.img"
InPanraster = "C:\\temp\\pan.tif"
#Compute Pan Sharpen Weights
out_pan_weight = arcpy.management.ComputePansharpenWeights(
InRGBraster, InPanraster, "3 2 1 4")
#Get results
pansharpen_weights = out_pan_weight.getOutput(0)
#Split the results string for weights of each band
pansplit = pansharpen_weights.split(";")
#Run the Create pan sharpened raster dataset tool.
arcpy.management.CreatePansharpenedRasterDataset(
InRGBraster, "3", "2", "1", "4", "C:\\temp\\pansharpened_raster.tif",
InPanraster, "Gram-Schmidt", pansplit[0].split(" ")[1],
pansplit[1].split(" ")[1], pansplit[2].split(" ")[1],
pansplit[3].split(" ")[1])
