名称

tile_imagestile_imagesTileImagesTileImagestile_images — Tile multiple image objects into a large image.

参数签名

描述

tile_imagestile_imagesTileImagesTileImagesTileImagestile_images tiles multiple input image objects, which must contain the same number of channels, into a large image. The input image object ImagesImagesImagesImagesimagesimages contains Num images, which may be of different size. The output image TiledImageTiledImageTiledImageTiledImagetiledImagetiled_image contains as many channels as the input images. In the output image the Num input images have been tiled into NumColumnsNumColumnsNumColumnsNumColumnsnumColumnsnum_columns 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 TileOrderTileOrderTileOrderTileOrdertileOrdertile_order determines the order in which the images are copied into the output in the cases in which this is not already determined by NumColumnsNumColumnsNumColumnsNumColumnsnumColumnsnum_columns (i.e., if NumColumnsNumColumnsNumColumnsNumColumnsnumColumnsnum_columns != 1 and NumColumnsNumColumnsNumColumnsNumColumnsnumColumnsnum_columns != Num). If TileOrderTileOrderTileOrderTileOrdertileOrdertile_order = 'horizontal'"horizontal""horizontal""horizontal""horizontal""horizontal" the images are copied in the horizontal direction, i.e., the second image of ImagesImagesImagesImagesimagesimages will be to the right of the first image. If TileOrderTileOrderTileOrderTileOrdertileOrdertile_order = 'vertical'"vertical""vertical""vertical""vertical""vertical" the images are copied in the vertical direction, i.e., the second image of ImagesImagesImagesImagesimagesimages will be below the first image. The domain of TiledImageTiledImageTiledImageTiledImagetiledImagetiled_image is obtained by copying the domains of ImagesImagesImagesImagesimagesimages to the corresponding locations in the output image. If Num is not a multiple of NumColumnsNumColumnsNumColumnsNumColumnsnumColumnsnum_columns the output image will have undefined gray values in the lower right corner of the image. The output domain will reflect this.

例程 (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')

结果

tile_imagestile_imagesTileImagesTileImagesTileImagestile_images 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
