paint_grayPaintGrayPaintGraypaint_graypaint_gray🔗

Short description🔗

paint_grayPaintGrayPaintGraypaint_graypaint_gray — Paint the gray values of an image into another image.

Signature🔗

paint_gray( image ImageSource, image ImageDestination, out image MixedImage )

Description🔗

paint_grayPaintGray paints the gray values of the image given in ImageSourceimageSourceimage_source into the image in ImageDestinationimageDestinationimage_destination and returns the resulting image in MixedImagemixedImagemixed_image. Only the gray values of the domain of ImageSourceimageSourceimage_source are copied (see reduce_domainReduceDomain).

As an alternative to paint_grayPaintGray, you can use the operator overpaint_grayOverpaintGray, which directly paints the gray values into ImageDestinationimageDestinationimage_destination.

Execution information🔗

Execution information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters🔗

ImageSourceimageSourceimage_source (input_object) (multichannel-)image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / vector_field)

Input image containing the desired gray values.

ImageDestinationimageDestinationimage_destination (input_object) (multichannel-)image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / vector_field)

Input image to be painted over.

MixedImagemixedImagemixed_image (output_object) image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex / vector_field)

Result image.

Example🔗

(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)

(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)\;

Result🔗

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