For example, below, a 720 x 576 image source (yellow) is used to generate a 1920 x 1080 mask (gray).
– Crop: If the image source is smaller than the generated mask, it is placed according to the X/Y
controls, masking off only a portion of the mask. If the image source is larger than the generated
mask it is placed according to the X/Y controls and cropped off at the borders of the mask.
– Stretch: The image source is stretched in X and Y to accommodate the full dimensions of the
generated mask. This might lead to visible distortions of the image source.
– Inside: The image source is scaled uniformly until one of its dimensions (X or Y) fits the inside
dimensions of the mask. Depending on the relative dimensions of the image source and mask
background, either the image source’s width or height may be cropped to fit the respective
dimension of the mask.
– Width: The image source is scaled uniformly until its width (X) fits the width of the mask.
Depending on the relative dimensions of the image source and mask, the image source’s Y
dimension might not fit the mask’s Y dimension, resulting in either cropping of the image source in
Y or the image source not covering the mask’s height entirely.
