tile_images (Operator)
tile_images
— Tile multiple image objects into a large image.
Signature
tile_images(Images : TiledImage : NumColumns, TileOrder : )
Description
tile_images
tiles multiple input image objects, which must
contain the same number of channels, into a large image. The input
image object Images
contains Num images, which may
be of different size. The output image TiledImage
contains
as many channels as the input images. In the output image the
Num input images have been tiled into NumColumns
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 TileOrder
determines the
order in which the images are copied into the output in the cases in
which this is not already determined by NumColumns
(i.e.,
if NumColumns
!= 1 and NumColumns
!=
Num). If TileOrder
= 'horizontal' the
images are copied in the horizontal direction, i.e., the second
image of Images
will be to the right of the first image.
If TileOrder
= 'vertical' the images are copied in
the vertical direction, i.e., the second image of Images
will be below the first image. The domain of TiledImage
is obtained by copying the domains of Images
to the
corresponding locations in the output image. If Num is not
a multiple of NumColumns
the output image will have
undefined gray values in the lower right corner of the image. The
output domain will reflect this.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.
Parameters
Images
(input_object) (multichannel-)image-array →
object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real)
Input images.
TiledImage
(output_object) (multichannel-)image →
object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real)
Tiled output image.
NumColumns
(input_control) integer →
(integer)
Number of columns to use for the output image.
Default: 1
Suggested values: 1, 2, 3, 4, 5, 6, 7
Restriction:
NumColumns >= 1
TileOrder
(input_control) string →
(string)
Order of the input images in the output image.
Default: 'vertical'
List of values: 'horizontal' , 'vertical'
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_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>:)
. If
necessary, an exception is raised.
