To save a defined image variable to file:

Use the [image->save] method on an image variable, specifying the desired image name, path, and format.

Code

local(myImage = image('image.jpg'))
#myImage->save('/images/image.jpg', -Quality=75)

---

To convert an image file from one format to another:

Use the [image->save] method on a defined image variable, changing the image file extension to the desired image format. A -Quality parameter value of 100 specifies that the resulting JPEG file will be saved at the highest-quality resolution.

Code

local(myImage = image('image.gif'))
#myImage->save('/images/image.jpg', -Quality=100)
