名称

paint_graypaint_grayPaintGrayPaintGraypaint_gray — 将一个图像的灰度值绘制到另一个图像中。

签名

paint_gray(ImageSource, ImageDestination : MixedImage : : )

描述

paint_graypaint_grayPaintGrayPaintGrayPaintGraypaint_gray paints the gray values of the image given in ImageSourceImageSourceImageSourceImageSourceimageSourceimage_source into the image in ImageDestinationImageDestinationImageDestinationImageDestinationimageDestinationimage_destination and returns the resulting image in MixedImageMixedImageMixedImageMixedImagemixedImagemixed_image. Only the gray values of the domain of ImageSourceImageSourceImageSourceImageSourceimageSourceimage_source are copied (see reduce_domainreduce_domainReduceDomainReduceDomainReduceDomainreduce_domain).

As an alternative to paint_graypaint_grayPaintGrayPaintGrayPaintGraypaint_gray, you can use the operator overpaint_grayoverpaint_grayOverpaintGrayOverpaintGrayOverpaintGrayoverpaint_gray, which directly paints the gray values into ImageDestinationImageDestinationImageDestinationImageDestinationimageDestinationimage_destination。

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

Input image containing the desired gray values.

ImageDestinationImageDestinationImageDestinationImageDestinationimageDestinationimage_destination (输入对象) (multichannel-)image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / vector_field)

Input image to be painted over.

Result image.

示例（HDevelop）

* Copy a circular part of the image 'monkey' into the image 'fabrik':

read_image(Image,'monkey')
gen_circle(Circle,200,200,150)
reduce_domain(Image,Circle,Mask)
read_image(Image2,'fabrik')
* Copy a part of the image 'monkey' into 'fabrik'
paint_gray(Mask,Image2,MixedImage)

示例（C）

/* Copy a circular part of the image 'monkey' into the image 'fabrik': */

read_image(&Image,"monkey");
gen_circle(&Circle,200.0,200.0,150.0);
reduce_domain(Image,Circle,&Mask);
read_image(&Image,"fabrik");
/* Copy a part of the image 'monkey' into 'fabrik' */
paint_gray(Mask,Image2,&MixedImage);
