我是python(2.6)的新手,具有使用gdal打开geotif的简单功能。它返回图像数组和图像大小(x,y)。
def gdal_open(raster_file):
if type(raster_file) is str and os.path.isfile(raster_file):
gd_img = gdal.Open(raster_file)
img_x = gd_img.RasterXSize # column
img_y = gd_img.RasterYSize # row
img = gd_img.ReadAsArray(0, 0, img_x, img_y)
elif type(raster_file) is str and not os.path.isfile(raster_file):
raise IOError
return img, img_x, img_y
我想将此转换为类以获取img,img.x和img.y作为输出。有人可以帮我吗?
谢谢, 杰伊

这是名称为IMG的类
class IMG:
def __init__(self,path):
if type(path)==str and os.path.isfile(path):
self.path=path
self.Raster=gdal.Open(path)
elif type(path)==str and not os.path.isfile(path):
raise IOError
def X(self):
return self.Raster.RasterXSize
def Y(self):
return self.Raster.RasterYSize
def RasterArray(self):
return self.Raster.ReadAsArray()
并使用它
filepath =“ path / raster_name.tif”
raster = IMG(文件路径)
xsize = raster.X()
ysize = raster.Y()
array = raster.RasterArray()
