Syntax

Saving an image in a file in JPEG format Hide the details

<Result> = <Image variable>.SaveJPEG(<File name> [, <Quality>])

<Result>: Boolean

True if the image was saved,
False otherwise. To get the details of the error, use ErrorInfo with the errMessage constant.

<Image variable>: Image variable

Name of the Image variable to use.

<File name>: Character string (with quotes)

Name and full (or relative) path of JPEG file. A UNC path can be used. The file extension is optional.

The existence of the JPEG file is not checked. This file is automatically overwritten if it already exists.

<Quality>: Optional integer

Quality of the image saved. Value included between 1 and 100 (80 by default). Lower image quality translates into higher image compression rate and smaller file size.
