Four general types of production vignettes are supported.
Recommended only when it is certain that only a single render image size is required.
Recommended when all desired render image sizes are known. Provides better quality and faster rendering than single-resolution and pyramid vignettes because the image does not need to be scaled after rendering.
Best all purpose, recommended when multiple image sizes are needed and the exact sizes are not pre-determined and when one of the Scene7 Flash zoom viewers are used.
Pyramid with one or more additional resolutions
Provides high quality for specific sizes while still providing flexibility and zoom viewer support.
Effectively, each resolution is saved to the production vignette as an independent view with its own image width and height.
The view size of a single-resolution vignette is specified with either
-height or both. If both values are specified, the vignette will be scaled so that neither dimension is larger than the specified size. If neither value is specified, the output vignette will have the same size as the input vignette. No upscaling will be applied; if the specified size is larger than the size of the input vignette, the output vignette will have the same size as the input vignette.
Effectively the same rules apply to multi-resolution vignettes, with the first resolution level being sized just like a single-resolution vignette. The additional resolutions are specified with additional comma-separated values for either
-height. Values do not need to be sorted. If
-width specifies multiple values, then
-height must only provide a single value, and vice versa, otherwise an error is returned.
A pyramid vignette is created by specifying
-pyramid. The largest resolution level of a such a vignette is determined exactly as for a single-resolution vignette. The additional resolution levels are determined automatically by scaling each level to 0.5x the previous level, with the smallest level not exceeding 128x128 pixels.
Additional resolution levels may be specified for a pyramid vignette, just like for a multi-resolution vignette.
