Image effects
The image effects feature allows imported images (bitmaps), image resources, viewports, image textures, and image-based Renderworks backgrounds, to be easily enhanced without requiring a time-consuming full rendering or the need to export to an external image program. More than one item can be selected and adjusted at the same time. Viewport styles can include image effects; if set by style the effects apply to all viewports that use that style and must be edited from the Edit Viewport Style dialog box.
Use the Eyedropper tool for Transferring attributes, including image effects, between bitmaps or viewports.
To adjust image effects for a selected bitmap, image resource, imported image, or viewport:
Do one of the following:
When importing an image file, click Image Effects from the Image Import Options dialog box (see Importing images).
Select a bitmap object, select Apply Image Effects, and then click Image Effects from the Object Info palette.
When creating resources using an image, click Image Effects from the Image Import Options dialog box (see Creating resources).
Once an image resource exists, right-click on it from the Resource Manager and select Edit Image Effects from the Resource viewer menus.
When modifying viewport properties or a viewport style (see Viewport properties or Creating and editing viewport styles), select Apply Image Effects, and then click Image Effects from the Object Info palette or Edit Viewport Style dialog box, or select Edit Image Effects from the context menu. The viewport must be rendered with Shaded mode or a Renderworks mode, and be updated.
When creating an image-based color shader (see Using an image in a texture shader), click Image Effects from the Edit Image Color dialog box.
When creating image backgrounds, click Image Effects from the Edit Image Background dialog box (see Creating image backgrounds).
The Image Effects dialog box opens.
