WIA_DPC_COMPRESSION_SETTING

The WIA_DPC_COMPRESSION_SETTING property contains either a range or a list of integers to represent perceived image quality.

Property Type: VT_I4

Valid Values: WIA_PROP_LIST or WIA_PROP_RANGE

Access Rights: Read/write

Remarks

The WIA_DPC_COMPRESSION_SETTING property is intended to approximately linearly describe the perceived image quality over a broad range of scene content. Smaller integers represent lower quality (that is, maximum compression), and larger integers represent higher quality (that is, minimum compression). Any available settings on a device are relative only to that device and are therefore device-specific.

Requirements

Version

Obsolete in Windows Vista and later operating systems and should no longer be used. However, this property is still defined in Windows Vista for compatibility with applications and devices designed for Windows Server 2003, Windows XP, and previous versions of Windows.
