Export Pole Figure Images

Group (Subgroup)

IO (Output)

Description

This Filter creates a standard pole figure image for each Ensemble in a selected Data Container with an Image Geometry. The Filter uses Euler angles in radians and requires the crystal structures for each Ensemble array and the corresponding Ensemble Ids on the Cells. The Filter also requires a mask array to determine which Cells are valid for the pole figure computation.

Algorithm Choice

1: The pole figure algorithm uses a modified Lambert square to perform the interpolations onto the circle. This is an alternate type of interpolation that the EBSD OEMs do not perform which may make the output from DREAM.3D look slightly different than output obtained from the OEM programs.

Only an advanced user with intimate knowledge of the modified Lambert projection should attempt to change the value for the "Lambert Image Size (Pixels)" input parameter.

2: Discrete Pole Figure

Parameters

Name Type Description
Pole Figure Type Enumeration: 0=Lambert, 1=Discrete Controls the type of pole figure
Image Format Enumeration Image file format to write. Currently supports .tif, .bmp, and .png file formats
Lambert Image Size (Pixels) int32_t Size of the Lambert square in pixels
Number of Colors int32_t Number of colors to use to make the pole figure
Image Layout Enumeration Layout for the resulting pole figure images, either square, horizontal, or vertical
Image Prefix String Prefix the prepend each pole figure file with
Output Path File Path Output directory path for images
Image Size (Square Pixels) int32_t Size of the output image in square pixels
Use Mask Array bool Specifies whether to use a boolean array to exclude some Cells. Only those cells that have a Mask Array value of 1 will be used.

Required Geometry
