Detailed Description

Defines the grid order when stitching in grid mode.

The grid order is used to convert a linear index into coordinates.

Two values are used to define the traversal. Here are some configuration examples:

GridTraversal = EStitchingGridDirection_RowMajor and GridStartingCorner = EStitchingGridStartingCorner_TopLeft. This is the default grid order configuration. | 0 | 1 | 2 | 3 | | 4 | 5 | 6 | 7 | | 8 | 9 | 10 | 11 |
GridTraversal = EStitchingGridDirection_ColumnMajor and GridStartingCorner = EStitchingGridStartingCorner_BottomRight. | 11 | 8 | 5 | 2 | | 10 | 7 | 4 | 1 | | 9 | 6 | 3 | 0 |
GridTraversal = EStitchingGridDirection_ColumnMajor_Snail and GridStartingCorner = EStitchingGridStartingCorner_BottomLeft. | 2 | 3 | 8 | 9 | | 1 | 4 | 7 | 10 | | 0 | 5 | 6 | 11 |

Member Function Documentation

◆ CustomTraversal()

list[eVision._eVision.EIntPoint] eVision.EStitchingGridOrder.CustomTraversal ( self )

Gets the custom traversal.

◆ GridStartingCorner() [1/2]

eVision.EStitchingGridStartingCorner eVision.EStitchingGridOrder.GridStartingCorner ( self )

Gets the grid position of the first image of the image list.

◆ GridStartingCorner() [2/2]

eVision.EStitchingGridOrder.GridStartingCorner	(		self,
		eVision.EStitchingGridStartingCorner	value )

Gets the grid position of the first image of the image list.

◆ GridTraversal() [1/2]

eVision.EStitchingGridTraversal eVision.EStitchingGridOrder.GridTraversal ( self )

Gets the type of grid traversal to apply.

◆ GridTraversal() [2/2]

eVision.EStitchingGridOrder.GridTraversal	(		self,
		eVision.EStitchingGridTraversal	value )

Gets the type of grid traversal to apply.

◆ HasCustomTraversal()

bool eVision.EStitchingGridOrder.HasCustomTraversal ( self )

Gets if a custom traversal (list of ordered image coordinates) has been set.

◆ ResetCustomTraversal()

None eVision.EStitchingGridOrder.ResetCustomTraversal ( self )

Resets the custom traversal.

If none are set or if the type of traversal is not set before using this class instance in the EImageStitcher an exception will be thrown.

◆ SetCustomTraversal()

None eVision.EStitchingGridOrder.SetCustomTraversal	(		self,
		int	colCount,
		int	rowCount,
		list[eVision._eVision.EIntPoint]	coordinates )

Sets the custom traversal.

The coordinates to specify is an ordered list of 2D coordinates where each image at index i is placed at the position (x, y) in the grid.

In the following example, we have a 3 by 3 grid where the traversal resembles a spiral:

| 6 | 7 | 8 | | 5 | 0 | 1 | | 4 | 3 | 2 |

The coordinates list to pass as arguments will look like (in pseudocode):

coordinates = [
  (1, 1), // 0
  (2, 1), // 1
  (2, 2), // 2
  (1, 2), // 3
  (0, 2), // 4
  (0, 1), // 5
  (0, 0), // 6
  (1, 0), // 7
  (2, 0), // 8
]

Each coordinate must be unique and the x and y components must be contained in [0, colCount[ and [0, rowCount[ respectively.
