Feature Representation

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

PNG features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.

Attribute Name	Contents
pngraster_type	This will always be pngraster_raster.
pngraster_title	Short (one line) title or caption for image.
pngraster_author	Name of image's creator.
pngraster_copyright	Copyright notice.
pngraster_description	Description of image (possibly long).
pngraster_software	Software used to create the image.
pngraster_disclaimer	Legal disclaimer.
pngraster_world_file_ generation	It enables or disables the generation of an Esri world file along with the output PNG image. The value can be yes or no. The default value is yes. This is a writer attribute.
pngraster_tab_file_generation	Enables or disables the generation of a TAB file along with the output PNG image. The value can be yes or no. The default value is yes. This is a writer attribute.
pngraster_optimize	Enables or disables optimization of the output PNG file. The default value is No_optimization. If enabled, optimization levels 1 through 7 can be set. Higher levels result in slower write times but may produce smaller files. Level 1 offers the fastest time and is recommended. This is a writer attribute.
