Example
After loading the image from the Upload Image command, the Scale Image command will resize its height and width to the specified scale, which in this context will be "10". After this operation, using the Get System Folder Path and Save Image commands, the scaled image is saved in the "My Documents" directory for analysis.
defVar --name scaledImage --type Image
defVar --name documensPath --type String
defVar --name scaledImagePath --type String
defVar --name image --type Image
// Download the following file to execute the command.
loadImage --file "wdg.PNG" image=value
// Resizes the image using a scale of "10".
scaleImage --image ${image} --scalefactor 10 scaledImage=value
// Get the path of the "My Documents" folder to save the scaled image.
getSpecialFolder --folder "MyDocuments" documensPath=value
saveImage --image ${scaledImage} --directory "${documensPath}" --file scaledImage --format "Jpeg" scaledImagePath=value
To view the change made by the command, go to the properties of the resized image saved in "My Documents" with the name "scaledImage". Then its width and height can be compared with the original image.
