public class GridThumbnailGridThumbnail
Used to define a request to download images and slice them into multiple thumbnails in a grid
pattern.
Each image will be sliced into smaller segments based on the gridWidth and gridHeight.
E.g. if these are both set to 2, then the image will be divided into a 2 x 2 grid producing 4
equal sized thumbnails per image.
The grid cells are ordered from left to right, then top to bottom.
Single or multiple images may be downloaded using this object. If maxIndex is greater than 1
and the pathTemplate contains the token index then multiple image urls can be specified.
The final image urls which will be downloaded are specified by the baseUrl + the result of the
pathTemplate substitution.
The index token in pathTemplate will be substituted with the index 1 up to and including
maxIndex.
E.g. if pathTemplate where image_$index$.jpg and maxIndex were 3, then image_1.jpg,
image_2.jpg, image_3.jpg would be generated from the substitution.
Each thumbnail will be displayed for durationMs with no gabs in between. Therefore thumbnails
will cover a total timerange of durationMs multiplied by the total number of thumbnails
generated.
