Image matching

Image matching activity is used to search for an image on a given source image. Starting from the X-Y point on the image, a search is made in an area equal to the determined width and height. If there is a match, the coordinate (X-Y) of the center point of the searched image on the searched image and the width/height values are assigned to the determined result variables. When x-position, y-position, width and height values aren’t entered, a search is made in the whole image.
*Source image Source image file name with path.
*Source image Base64 Source image with base64 string. If image and its path are given in Source image field, Source image Base64 must not be used. In case of using it, an error will be returned.
*Searched image File name and path of the image to be searched.
*Searched image Base64 Searched image with base64 string.
X-coordinate If it is desired to limit the image to be searched on the screen within a certain area; this field must be filled in, along with the Y-coordinate, Height, and Width fields.
Y-coordinate If it is desired to limit the image to be searched on the screen within a certain area; this field must be filled in, along with the X-coordinate, Height, and Width fields.
Width If it is desired to limit the image to be searched on the screen within a certain area; this field must be filled in, along with the X-coordinate, Y-coordinate and Height fields.
Height If it is desired to limit the image to be searched on the screen within a certain area; this field must be filled in, along with the X-coordinate, Y-coordinate and Width fields.
Start scale If it is desired to try again when the searched image is not found on the image, the Start Scale field is filled. Specifies the start scale. Scale statements are double-type numbers (0.1, 0.5, 2.0).
End scale If it is desired to try again when the searched image is not found on the image, the Start Scale field is filled. Specifies the end scale. Scale statements are double-type numbers (0.1, 0.5, 2.0).
Scale step If it is desired to try again when the searched image is not found on the image, the Start Scale field is filled. Specifies the progression coefficient. Specifies the progression coefficient.
Match score Images are matched if their similarity percentage is higher than the match score.
*Return x-position If the image matches, the x-coordinate of the center point of the searched image is assigned to this variable.
*Return y-position If the image matches, the y-coordinate of the center point of the searched image is assigned to this variable.
*Return height If the image matches, the height of the center point of the searched image is assigned to this variable.
*Return width If the image matches, the width of the center point of the searched image is assigned to this variable.

Note: * Fields selected with are required, others are optional.
