1. 使用 ListFiles 函数获取需要处理的所有栅格图层的路径名(这些图层必须是 ArcGIS 支持的栅格格式,例如:JPEG、TIFF、PNG 等),然后再遍历图层列表执行操作。示例代码如下: import arcpy from arcpy.sa import * # Set input file path and output folder path in_path = "D:/path/to/input/folder" out_folder = "D:/path/to/output/folder" # Obtain a list of all raster files in the input folder all_files = arcpy.ListFiles("*", "Raster", in_path) for in_file in all_files: # Check whether the raster is a JPEG and is worth processing if not (in_file.endswith(".jpg") or in_file.endswith(".jpeg")): continue # Compose the output file name and path out_file = in_file[:-4] + ".jpg" out_path = out_folder + "/" + out_file # Execute the RasterToOtherFormat_conversion function to convert the input raster to JPEG format arcpy.RasterToOtherFormat_conversion(in_file, out_path, "JPEG")2. 如果您还需要针对不同的图层指定不同的输出参数,可以在循环体中添加变量来保存这些自定义配置。例如,如果您有多个输入文件夹和多个输出文件夹,并且需要为每个图层指定输出分辨率和压缩质量,则可以创建一个字典,将输入/输出文件夹和输出参数保存在其中: import arcpy from arcpy.sa import * # Define the input/output file locations and output parameters file_config = { "input_folder": "D:/path/to/input/folder", "output_folder": "D:/path/to/output/folder", "out_resolution": 200, "out_quality": 80 } # Obtain a list of all raster files in the input folder all_files = arcpy.ListFiles("*", "Raster", file_config["input_folder"]) for in_file in all_files: # Check whether the raster is worth processing if not (in_file.endswith(".jpg") or in_file.endswith(".jpeg")): continue # Compose the output file name and path out_file = in_file[:-4] + ".jpg" out_path = file_config["output_folder"] + "/" + out_file # Execute the RasterToOtherFormat_conversion function to convert the input raster to JPEG format, using specified output parameters arcpy.RasterToOtherFormat_conversion(in_file, out_path, "JPEG", "", "", file_config["out_resolution"], "", "", "", "", "", "", file_config["out_quality"])注意:在执行上述操作时,请确保对应文件的路径和格式信息是否正确,并检查计算机性能和资源使用情况等问题。 |
