[Setup]: WizardBackImageOpacity

Valid values:

0 through 255

Default value:

255
Description:

If set to 0, the background wizard image set via WizardBackImageFile will be fully transparent. If set to 255, the wizard images will be fully opaque (non-transparent).

This is useful if you want to use an identical regular and DynamicDark background image. For example, you can set WizardBackImageOpacity to 150 to achieve partial transparency.

Example:
WizardStyle=modern dynamic
WizardBackImageFile=MyBackImage.png
WizardBackImageFileDynamicDark=MyBackImage.png
WizardBackImageOpacity=150
