Controlling GDI+ Features at Run Time

Foundation > Using Rogue Wave Views on Microsoft Windows > Using GDI+ Features with Rogue Wave Views > Controlling GDI+ Features at Run Time

It is possible to specify, through a resource or an environment variable. if you want GDI+ to be used. The following table summarizes the possible values and the effect of each:

GDI+ Resources
Resource (.ini file)	Environment Variable	Value
UseGdiPlus	ILVUSEGDIPLUS	needed: GDI+ is used only when it is needed, for example, when transparency or anti-aliasing is required. This is the default. true: GDI+ is used each time it is possible. false: GDI+ is never used.
UseGdiPlusPrinting	ILVUSEGDIPLUSPRINTING	false: GDI+ is not used for printing. By default, GDI+ is used for printing.

For example, the following views.ini file sets GDI+ to be used each time it is possible:

[Views]

UseGdiPlus=true

Rogue Wave Views Cairo integration does not support text rendering using gradients. In order for GDI+ to use identical rendering to Cairo, the GDI+ feature in Rogue Wave Views is set, by default, not to use gradients for text renderings. To force Rogue Wave Views to allow GDI+ text renderings using gradients, you can set the following resource or environment variable:

GDI+ Resource for text rendering

Resource (.ini file)	Environment Variable	Value
UseGradientText	ILVUSEGRADIENTTEXT	true: Allow the use of gradients to render text.
