Description
Returns a bitmap item having the specified scale from the current multi-resolution bitmap.
ItemByScale searches for a bitmap item having the specified AScale scale in the current multi-resolution bitmap:
- If ExactMatch is
True, ItemByScale returns only a bitmap item that exactly matches the specified AScale scale. Otherwise, ItemByScale returns a bitmap item having the most appropriate scale. - If IncludeEmpty is
True, then ScaleArray can return a bitmap item having an empty bitmap. Otherwise, ScaleArray returns only a bitmap item not having an empty bitmap.
ItemByScale returns the retrieved TCustomBitmapItem bitmap item. If ItemByScale does not find an appropriate bitmap item, then it returns nil.
