calculateRenderedImageSize

public static ObjectFitApplyingResult calculateRenderedImageSize(ObjectFit objectFit,
                                                                 double absoluteImageWidth,
                                                                 double absoluteImageHeight,
                                                                 double imageContainerWidth,
                                                                 double imageContainerHeight)

Calculates size of image to be render when certain ObjectFit mode is applied. The width or the height of the image might be greater than the same property of the image in a document. In this case parts of the image will not be shown.

Parameters:

objectFit - is an object-fit mode

absoluteImageWidth - is a width of the original image

absoluteImageHeight - is a height of the original image

imageContainerWidth - is a width of the image to draw

imageContainerHeight - is a width of the image to draw

Returns:

results of object-fit mode applying as an ObjectFitApplyingResult object
