This item was deprecated in version 2019r2. Please use `Picture.ApplyMask` and `Picture.CopyMask` as a replacement.
## Description
Allows you to access a Mask that controls the transparency of the picture. By default, the optional Create parameter is `True`. When Create is `True`, the Mask is created automatically; otherwise the Mask is returned, whether or not one exists.
## Notes
The Mask property returns Nil when you are using a Picture created with an alpha channel (this includes HiDPI images). You can get at masks by using the `CopyMask` and `ApplyMask` methods instead.
## Sample code
This example opens a jpeg file and creates a Mask.
``` xojo
Dim p2 As Picture
Dim pic As Picture
Dim f As FolderItem
f = GetOpenFolderItem("image/jpeg")
If f <> Nil Then
pic = Picture.Open(f)
p2 = pic.Mask(True)
End If
```
## Compatibility
All project types on all supported operating systems.
