filter.h contains the following programming interfaces:
Interfaces
| IFilter Scans documents for text and properties (also called attributes). |
| IPixelFilter Implemented by search filters to return chunks containing the raw pixels and properties for images to enable semantic indexing of images. |
Structures
| FILTERREGION Describes the position and extent of a specified portion of text within an object. |
| FULLPROPSPEC Specifies a property set and a property within the property set. |
| IMAGE_INFO Represents image metadata, including dimensions and format. This structure is populated by a search filter and returned from its implementation of IPixelFilter::GetImageInfo. |
| STAT_CHUNK Describes the characteristics of a chunk. |
Enumerations
| CHUNK_BREAKTYPE Describes the type of break that separates the current chunk from the previous chunk. |
| CHUNKSTATE Specifies whether the current chunk is a text-type property or a value-type property. |
| IFILTER_FLAGS Indicates whether the caller should use the IPropertySetStorage and IPropertyStorage interfaces to locate additional properties. |
| IFILTER_INIT Flags that control the filtering process. |
| IMAGE_PIXELFORMAT Specifies the pixel format of an image. This enumeration is used with the IMAGE_INFO structure. |
