Examples

The following example applies various types of filters to a raster image.

from aspose.pycore import as_of
from aspose.imaging import Image, RasterImage
from aspose.imaging.imagefilters.filteroptions import *
from os.path import join as join_path

directory = r"c:\temp"

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用矩形大小为 5 的中值滤波器。
	rasterImage.filter(rasterImage.bounds, MedianFilterOptions(5))
	rasterImage.save(join_path(directory, "sample.MedianFilter.png"))

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用核大小为 5 的双边平滑滤波器。
	rasterImage.filter(rasterImage.bounds, BilateralSmoothingFilterOptions(5))
	rasterImage.save(join_path(directory, "sample.BilateralSmoothingFilter.png"))

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用半径为 5、sigma 值为 4.0 的高斯模糊滤波器。
	rasterImage.filter(rasterImage.bounds, GaussianBlurFilterOptions(5, 4.0))
	rasterImage.save(join_path(directory, "sample.GaussianBlurFilter.png"))

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用半径为 5、平滑值为 4.0 的 Gauss-Wiener 滤波器。
	rasterImage.filter(rasterImage.bounds, GaussWienerFilterOptions(5, 4.0))
	rasterImage.save(join_path(directory, "sample.GaussWienerFilter.png"))

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用长度为 5、平滑值为 4.0、角度为 90.0 度的运动 Wiener 滤波器。
	rasterImage.filter(rasterImage.bounds, MotionWienerFilterOptions(10, 1.0, 90.0))
	rasterImage.save(join_path(directory, "sample.MotionWienerFilter.png"))
}

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# 对整幅图像应用核大小为 5、sigma 值为 4.0 的锐化滤波器。
	rasterImage.filter(rasterImage.bounds, SharpenFilterOptions(5, 4.0))
	rasterImage.save(join_path(directory, "sample.SharpenFilter.png"))
