Accessing Feature Type Parameters
|
To access feature type parameters, click the gear icon Tip To always display the editor in FME Workbench, you can select View > Window Layout > Parameter Editor.
General All feature types share similar General parameters, which may include Feature Type Name, Reader or Writer information, and Geometry. In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept Table or Index Qualifier prefixes on the output table feature type. |
on a feature type in the Raster Compression
Method
Sets the compression method for the raster.
Values: DXT1, DXT1A, DXT3, DXT5, ETC1
DXT1 and ETC1 produce approximately equivalent file sizes. DXT3 and DXT5 give file sizes two times the size of DXT1 and ETC1. DXT1 and ETC1 compressed files store RGB data while DXT3 and DXT5 store RGBA data. DXT1A is simply DXT1 compression with an alpha channel that can indicate full transparency or no transparency.
Default: DXT1
Quality
Sets the quality of the raster post-compression.
Highest is the slowest but has the best Peak Signal-to-Noise Ratio (PSNR), leading to higher texture quality.
The Fastest setting can yield a tenfold increase in writing speed compared to the Highest setting, but leads to slightly lower texture quality.
Values: Fastest, Fast, Normal, High, Highest
Default: Normal
