Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format adds the format-specific attributes described in this topic.

Attribute Name	Contents
webp_type	This will always be webp_raster.
webp_lossless_encoding	Enables or disables lossless encoding. With lossless encoding, the compressed image is identical to the original; with lossy encoding, the compressed image is an approximation of the original. This is a writer attribute.
webp_compression_level	Specifies the desired compression level. Higher values will produce smaller output file sizes, but will be poorer quality. Range: 0 (best quality) to 100 (worst quality) Default: 25 This value is ignored if webp_lossless_encoding is set to Yes. This is a writer attribute.
webp_image_type	Specifies the image type. Choosing an image type that suits the image may result in better quality for a given level of compression. Valid image types are: Default Picture: For digital pictures, like portraits or inner shots. Photo: For outdoor photographs with natural lighting. Drawing: For hand or line drawings, with high-contrast details. Icon: For small-sized colorful images. Text: For text-like images. This value is ignored if webp_lossless_encoding is set to Yes. This is a writer attribute.
