Description

overpaint_grayoverpaint_grayOverpaintGrayoverpaint_grayOverpaintGrayOverpaintGray copies the gray values of the image given in ImageSourceImageSourceImageSourceImageSourceImageSourceimageSource into the image in ImageDestinationImageDestinationImageDestinationImageDestinationImageDestinationimageDestination. Only the gray values of the domain of ImageSourceImageSourceImageSourceImageSourceImageSourceimageSource are copied (see reduce_domainreduce_domainReduceDomainreduce_domainReduceDomainReduceDomain).

If you do not want to modify ImageDestinationImageDestinationImageDestinationImageDestinationImageDestinationimageDestination itself, you can use the operator paint_graypaint_grayPaintGraypaint_grayPaintGrayPaintGray, which returns the result in a newly created image.

Attention

overpaint_grayoverpaint_grayOverpaintGrayoverpaint_grayOverpaintGrayOverpaintGray modifies the content of an already existing image (ImageDestinationImageDestinationImageDestinationImageDestinationImageDestinationimageDestination). Besides, even other image objects may be affected: For example, if you created ImageDestinationImageDestinationImageDestinationImageDestinationImageDestinationimageDestination via copy_objcopy_objCopyObjcopy_objCopyObjCopyObj from another image object (or vice versa), overpaint_grayoverpaint_grayOverpaintGrayoverpaint_grayOverpaintGrayOverpaintGray will also modify the image matrix of this other image object. Therefore, overpaint_grayoverpaint_grayOverpaintGrayoverpaint_grayOverpaintGrayOverpaintGray should only be used to overpaint newly created image objects. Typical operators for this task are, e.g., gen_image_constgen_image_constGenImageConstgen_image_constGenImageConstGenImageConst (creates a new image with a specified size), gen_image_protogen_image_protoGenImageProtogen_image_protoGenImageProtoGenImageProto (creates an image with the size of a specified prototype image) or copy_imagecopy_imageCopyImagecopy_imageCopyImageCopyImage (creates an image as the copy of a specified image).

Example (HDevelop)

* Copy a circular part of the image 'monkey' into a new image (New1):

read_image(Image,'monkey')
gen_circle(Circle,200,200,150)
reduce_domain(Image,Circle,Mask)
* New image with black (0) background
gen_image_proto(Image,New1,0.0)
* Copy a part of the image 'monkey' into New1
overpaint_gray(New1,Mask)

Example (C)

/* Copy a circular part of the image 'monkey' into a new image (New1): */

read_image(&Image,"monkey");
gen_circle(&Circle,200.0,200.0,150.0);
reduce_domain(Image,Circle,&Mask);
/* New image with black (0) background */
gen_image_proto(Image,&New1,0.0);
/* Copy a part of the image 'monkey' into New1 */
overpaint_gray(New1,Mask);

Result

overpaint_grayoverpaint_grayOverpaintGrayoverpaint_grayOverpaintGrayOverpaintGray returns 2 (H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
