WIA_IPC_THUMBNAIL

The WIA_IPC_THUMBNAIL property contains the 24-bits-per-pixel thumbnail data bits. The WIA minidriver creates and maintains this property.

Property Type: VT_UI1 | VT_VECTOR

Valid Values: WIA_PROP_NONE

Access Rights: Read-only

Remarks

The thumbnail data that the WIA_IPC_THUMBNAIL property contains must be in uncompressed bitmap data and aligned on 32-bit boundaries. An application reads the values of the WIA_IPC_THUMBNAIL_WIDTH and WIA_IPC_THUMBNAIL_HEIGHT properties and creates a BITMAPINFOHEADER structure (which is described in the Microsoft Windows SDK documentation). The application should be able to read the WIA_IPC_THUMBNAIL property (which represents the actual thumbnail image data) and use this property to write the data directly into the newly created bitmap to create the thumbnail image.

WIA_IPC_THUMBNAIL is used by WIA minidrivers and applications that are running on Microsoft Windows XP, Windows Me, and later versions of the operating system.

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.
