Description
Creates a new image view on the given window covering the area of the given control.Use ImageView.Release later to destroy the image view.
If you use a register (tab controls) on the window, be aware that the image view actually is in front of the register (tab controls). So you need to check in the script which register page is current and should show what image view. Or by a trigger you turn the visibility on and off.
Image view reference numbers are starting at 74000 and counting up for each new image view.
Examples
Create image view with control as placeholder:
# Query size of image
Set Variable [ $Image ; Value: MBS( "GMImage.NewFromContainer"; ImageView::ImageContainer ) ]
Set Variable [ $w ; Value: MBS( "GMImage.GetWidth"; $Image ) ]
Set Variable [ $h ; Value: MBS( "GMImage.GetHeight"; $Image ) ]
Set Variable [ $r ; Value: MBS( "GMImage.Release"; $Image ) ]
# We play half size for retina screen resolution
Set Variable [ $h ; Value: Round($h/2;0) ]
Set Variable [ $w ; Value: Round($w/2;0) ]
# We play half size for retina screen resolution
Set Variable [ $$ImageView ; Value: MBS("ImageView.CreateWithControl"; 0; "PlaceHolder") ]
Set Variable [ $r ; Value: MBS("ImageView.SetImage"; $$ImageView; ImageView::ImageContainer) ]
