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

<Result> = dSaveImageJPEG(<Image name> , <File name> [, <Quality> [, <Exif tag>]])
<Result>: Boolean

  • 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.
<Exif tag>: Optional constant (or combination of constants)
Record of Exif tags modified with ImageInfoModify:
imgAddThumbnailAdds a thumbnail into the image file (<File name>).
If there is a thumbnail in the image file displayed in the Image control, this constant is not taken into account.
