Method Details

maxReductionFactor

public static int maxReductionFactor(Size fullSize,
 int minDimension)

Parameters:

fullSize - Full size of the source image.

minDimension - Minimum allowed dimension.

Returns:

Maximum reduction factor to be able to fit above the minimum allowed dimension.

minReductionFactor

public static int minReductionFactor(Size fullSize,
 long maxPixels)

Parameters:

fullSize - Full size of the source image.

maxPixels - Maximum allowed number of pixels.

Returns:

Minimum reduction factor to be able to fit below the maximum allowed number of pixels.

getTileSize

public static Size getTileSize(Size fullSize,
 Size physicalTileSize,
 int minSize)

Calculates an optimal information tile size based on a given physical image tile size.

Parameters:

fullSize - Size of the full source image.

physicalTileSize - Size of the source image's tiles. If the source image is not natively tiled, this should be equal to fullSize.

minSize - Minimum allowed dimension.

Returns:

Information tile size.
