Stored procedures
Saves an image:
  • in a JPEG file.
  • in memory.
This image corresponds to the image contained in a Image control.
Remarks:
  • Only the visible part of the Image control is saved.
  • This function can only be used to save the images for screen resolutions up to 32 bits.
  • This function cannot be used with the Image controls found in the reports.
  • This function can also be used to save the changes made by ImageInfoModify on the Exif tags of an image.
  • Java Saving images in JPEG format is supported only if the application is run by the Java Virtual Machine (JVM) distributed by SUN. Images in JPEG format cannot be saved with other Java virtual machines.
Linux Caution: A specific configuration is required to use this function in Linux. For more details, see The drawings.

Saving an image in a JPEG file Hide the details

<Result> = <Image variable>.SaveJPEG(<File name> [, <Quality>])
<Result>: Boolean
  • True if the image was saved,
  • False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
<Image variable>: Image variable
  • Name of the Image, Bar Code or Web Camera control to be used. Image controls in a report cannot be used.
  • WEBDEV - Server code Name of the Image or Web Camera control to be used.
  • AndroidJava Name of the Image control to be used.
<File name>: Character string
Name and full (or relative) path of JPEG file. A UNC path can be used. The file extension is optional.
Caution:
  • The destination directory must exist in order for the image to be saved.
  • 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 between 1 and 100 (80 by default). Lower image quality translates into higher image compression rate and smaller file size.
