This function is used to test for missing artwork or for artwork which is smaller than a specified size. Artwork searches are always based on a file's first artwork item.
The default method is to test if either of an artwork item's width or height is less than the specified size. If you wish the test to fail only if both the width and height are less than the specified size, select the w & h option.
The action test state will be set to true whenever the size test fails. If the artwork exists and meets the size condition, the action test state will be set to false.
If a size test option is not provided, (a size of 0), the condition is based on the existence of at least one artwork item. The action test state is set to true only if no artwork exists.
The function stops in stepwise mode if any selected file sets the state to true.
