Remarks

Finding out the display mode and the alignment mode of an image (syntax 1)

The Property ImageMode returns a single value representing both the Image display mode and the alignment mode..

To separate the alignment information from the display information, a binary filter must be applied in order to subtract the display mask or the alignment mask from the result (BinaryAND).

Tip: To only retrieve the value corresponding to the alignment mode, apply a binary mask whose value is the reunion of all alignment constants. The remaining constant will be the alignment constant used in the image. For example:

CurrentMode is int
MaskAlignmentMode is int
AlignmentMode is int

CurrentMode = IMG_Photo.ImageMode

MaskAlignmentMode = imgAlignHCentered + imgAlignHRight + imgAlignVBottom + imgAlignVCentered

AlignmentMode = BinaryAND(CurrentMode, MaskAlignmentMode)
Info(AlignmentMode)

Limits

The Property ImageMode applies only:

the Image controls,
the Image columns found in the Table controls,
the Chart controls found in the windows,
Versions 22 and later
the Button controls.
New in version 22
the Button controls.
the Button controls.

The Property ImageMode applies only to Image fields.

If the display mode is modified by programming, the content of the image must be re-assigned to view the changes.
