Imaging GUIDs (Windows CE 5.0)
The Imaging API defines several groups of GUIDs that you can use to identify specific data formats and parameters associated with images and image encoders.
To use these GUIDs, add the following lines of code to your application's source code prior to any other #include statements that might directly or indirectly include Windows.h.
#define INITGUID
#include <windows.h>
#include <imaging.h>
#undef INITGUID
Image Format Identifiers
The following table shows GUIDs used to identify file formats for images.
| GUID | Description |
|---|---|
| ImageFormatUndefined | Indicates an image from an unidentified file format. |
| ImageFormatMemoryBMP | Indicates an image from a bitmap in memory rather than in a file. |
| ImageFormatBMP | Indicates an image from a bitmap file. |
| ImageFormatEMF | Not supported. |
| ImageFormatWMF | Not supported. |
| ImageFormatJPEG | Indicates an image from a JPEG file. |
| ImageFormatPNG | Indicates an image from a PNG file. |
| ImageFormatGIF | Indicates an image from a GIF file. |
| ImageFormatTIFF | Indicates an image from a TIFF file. |
| ImageFormatEXIF | Indicates an image from an EXIF file. |
| ImageFormatIcon | Indicates an image from an icon file. |
Multi-frame Dimension Identifiers
The following table shows GUIDs used to identify major dimensions for multi-frame images.
| GUID | Description |
|---|---|
| FrameDimensionTime | Indicates the time of the image. |
| FrameDimensionResolution | Indicates the resolution of the image. |
| FrameDimensionPage | Indicates the page of the image. |
Property Set Identifiers
The following table shows GUIDs used to identify categories of property sets for images.
| GUID | Description |
|---|---|
| FormatIDImageInformation | Indicates a property set for data about the image. |
| FormatIDJpegAppHeaders | Indicates a property set for JPEG application headers. |
Decoder Parameter Identifiers
The following table shows GUIDs used to identify parameters for image decoders.
| GUID | Description |
|---|---|
| DECODER_TRANSCOLOR | Identifies the decoder's transparency color settings. |
| DECODER_TRANSRANGE | Identifies the decoder's transparency range settings. |
| DECODER_OUTPUTCHANNEL | Identifies the decoder's output channel. |
| DECODER_ICONRES | Identifies the decoder's icon resolution. |
| DECODER_USEICC | Identifies the decoder's support for color management through International Color Consortium (ICC) profiles. |
Encoder Parameter Identifiers
The following table shows GUIDs used to identify parameters for image encoders.
| GUID | Description |
|---|---|
| EncoderCompression | Identifies the encoder's compression settings. |
| EncoderColorDepth | Identifies the encoder's color depth settings. |
| EncoderScanMethod | Identifies the encoder's scan mode settings, including whether an image is interlaced or noninterlaced. |
| EncoderVersion | Identifies the encoder's software version settings. |
| EncoderRenderMethod | Identifies the encoder's render method settings, including whether an image should be rendered in a progressive or nonprogressive mode. |
| EncoderQuality | Identifies the encoder's quality settings. |
| EncoderTransformation | Identifies the encoder's transformation settings. |
| EncoderLuminanceTable | Identifies the encoder's luminance table settings. |
| EncoderChrominanceTable | Identifies the encoder's chrominance table settings. |
| EncoderSaveFlag | Identifies the encoder's save flag settings. |
| CodecIImageBytes | Identifies the encoder's memory settings. |
