bRet = Image.Exists(objUiElement,objRect,sImagePath,iAccuracy,iTimeOut,optionArgs)

Find the image in the specified range, and return true if found, and return false if otherwise

Required Parameter: objUiElement--Correspond to the UI element to operate; when passed as a string type, it is used as feature string to find the UI element; when passed as UiElement type, directly click its matching UI element; objRect--The area in the control where the program will recognize images. If the area is passed as {"x":0,"y":0,"width":0,"height":0}, then execute image recognition in this rectangle area of the control; sImagePath--The path to the image to find, generally in the res folder; iAccuracy--Similarity to be used for finding images, ranging from 0.5 - 1.0, ie. similarity of 50% - 100%; iTimeOut-- Specify the time (in milliseconds) to wait for an activity to run before SelectorNotFoundException throws an error. The default is 10000 milliseconds (10 seconds)

Optional Parameter: bContinueOnError--Specify whether automation should continue if the activity throws an error. This field only supports Boolean values (True, False). The default is False; iDelayAfter--The delay in milliseconds after the activity is executed. The default is 300 milliseconds; iDelayBefore--The delay in milliseconds before the activity starts any operation. The default is 200 milliseconds; bSetForeground--Activate the target window or not before the operation; sMatchType--Specify a match type for an image, gray match is fast, but it may fail in extreme situation. the color match is more accurate than gray match, but the matching speed is slightly slower.
