CiImage Object : Save Method

Description

Save image into its image file

Syntax

Visual Basic
Public Sub Save()

Remarks

!MISSING PHRASE '_ZONEFAIL_IMG'!

Method  saves image using format specified in Format property.  Some formats are "read-only" and are not supported by this method.

Some formats use lossy compression.   Therefore saving image in such format will modify saved image.
Amount of JPEG compression is controlled by JpegQuality parameter.

Not each format supports all CiImage. BitsPerPixel values.   Image is converted to the nearest supported BPP prior to saving.
For example Bitonal image is converted to Grayscale prior to saving using JPEG format.  Resulting file image might have blocking effect, typical for JPEG  lossy compression.
