tile_imagestile_imagestile_imagesTileImagesTileImages (Operator)

Name

tile_imagestile_imagestile_imagesTileImagesTileImages — Tile multiple image objects into a large image.

Signature

Description

tile_imagestile_imagestile_imagesTileImagesTileImages tiles multiple input image objects, which must contain the same number of channels, into a large image. The input image object ImagesImagesImagesImagesimages contains Num images, which may be of different size. The output image TiledImageTiledImageTiledImageTiledImagetiledImage contains as many channels as the input images. In the output image the Num input images have been tiled into NumColumnsNumColumnsNumColumnsNumColumnsnumColumns columns. Each tile has the same size, which is determined by the maximum width and height of all input images. If an input image is smaller than the tile size it is copied to the center of the respective tile. The parameter TileOrderTileOrderTileOrderTileOrdertileOrder determines the order in which the images are copied into the output in the cases in which this is not already determined by NumColumnsNumColumnsNumColumnsNumColumnsnumColumns (i.e., if NumColumnsNumColumnsNumColumnsNumColumnsnumColumns != 1 and NumColumnsNumColumnsNumColumnsNumColumnsnumColumns != Num). If TileOrderTileOrderTileOrderTileOrdertileOrder = 'horizontal'"horizontal""horizontal""horizontal""horizontal" the images are copied in the horizontal direction, i.e., the second image of ImagesImagesImagesImagesimages will be to the right of the first image. If TileOrderTileOrderTileOrderTileOrdertileOrder = 'vertical'"vertical""vertical""vertical""vertical" the images are copied in the vertical direction, i.e., the second image of ImagesImagesImagesImagesimages will be below the first image. The domain of TiledImageTiledImageTiledImageTiledImagetiledImage is obtained by copying the domains of ImagesImagesImagesImagesimages to the corresponding locations in the output image. If Num is not a multiple of NumColumnsNumColumnsNumColumnsNumColumnsnumColumns the output image will have undefined gray values in the lower right corner of the image. The output domain will reflect this.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on channel level.

Parameters

Example (HDevelop)

* Grab 5 (multi-channel) images and stack them vertically.
gen_empty_obj (Images)
for I := 1 to 5 by 1
    grab_image_async (ImageGrabbed, AcqHandle, -1)
    concat_obj (Images, ImageGrabbed, Images)
endfor
tile_images (Images, TiledImage, 1, 'vertical')

Result

tile_imagestile_imagestile_imagesTileImagesTileImages returns 2 (H_MSG_TRUE) if all parameters are correct and no error occurs during execution. If the input is empty the behavior can be set via set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
