Image Reference In

An Image reference is a handle to the actual image data in memory. It's important to note that you are responsible for manually releasing (deallocating) the memory associated with this image reference when it's no longer needed to prevent memory leaks.

cbool

Include Border

Include Border Pixels: Set to TRUE to include border pixels from the Optional Rectangle in the output array (default: FALSE).

Step Sizes

    cu32

    X Step Size

    Horizontal sampling step defining which rows from the source image are included in the data array (vertical reduction). A value of 2 includes every second row; 1 includes all rows.

    cu32

    Y Step Size

    Vertical sampling step defining which columns from the source image are included in the data array (horizontal reduction). A value of 3 includes every third column; 1 includes all columns.

Line Info

    iu32

    Total Width

    Nmber of elements in the data array representing one image line. For 2D/3D arrays, it's the size of the second dimension. For 1D arrays, it's the length of a line segment. Incrementing the array offset by Total Width moves to the next line.

    iu32

    Left Border

    Number of array elements representing the left border for each image line.

    iu32

    Image Data

    Number of array elements containing the actual image data for each line within the optional rectangle.

    iu32

    Right Border

    Number of array elements representing the right border for each image line.

    iu32

    Padding

    Number of array elements representing the end-of-line alignment padding.
