public final class WmfCompression extends System.Enum
The Compression Enumeration specifies the type of compression for a bitmap image
Fields
| Field | Description |
|---|---|
| BI_RGB | The bitmap is in uncompressed red green blue (RGB) format that is not compressed and does not use color masks. |
| BI_RLE8 | An RGB format that uses run-length encoding (RLE) compression for bitmaps with 8 bits per pixel. |
| BI_RLE4 | An RGB format that uses RLE compression for bitmaps with 4 bits per pixel. |
| BI_BITFIELDS | The bitmap is not compressed and the color table consists of three DWORD color masks that specify the red, green, and blue components, respectively, of each pixel. |
| BI_JPEG | The image is a JPEG image, as specified in [JFIF]. |
| BI_PNG | The image is a PNG image, as specified in [RFC2083]. |
| BI_CMYK | The image is an uncompressed CMYK format. |
| BI_CMYKRLE8 | A CMYK format that uses RLE compression for bitmaps with 8 bits per pixel. |
| BI_CMYKRLE4 | A CMYK format that uses RLE compression for bitmaps with 4 bits per pixel. |
BI_RGB
public static final int BI_RGB
The bitmap is in uncompressed red green blue (RGB) format that is not compressed and does not use color masks.
BI_RLE8
public static final int BI_RLE8
An RGB format that uses run-length encoding (RLE) compression for bitmaps with 8 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by a byte containing a color index.
BI_RLE4
public static final int BI_RLE4
An RGB format that uses RLE compression for bitmaps with 4 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by two word-length color indexes
BI_BITFIELDS
public static final int BI_BITFIELDS
The bitmap is not compressed and the color table consists of three DWORD color masks that specify the red, green, and blue components, respectively, of each pixel. This is valid when used with 16 and 32-bits per pixel bitmaps.
BI_JPEG
public static final int BI_JPEG
The image is a JPEG image, as specified in [JFIF]. This value SHOULD only be used in certain bitmap operations, such as JPEG pass-through. The application MUST query for the pass-through support, since not all devices support JPEG pass-through. Using non-RGB bitmaps MAY limit the portability of the metafile to other devices. For instance, display device contexts generally do not support this pass-through
BI_PNG
public static final int BI_PNG
The image is a PNG image, as specified in [RFC2083]. This value SHOULD only be used certain bitmap operations, such as JPEG/PNG pass-through. The application MUST query for the pass-through support, because not all devices support JPEG/PNG pass-through. Using non-RGB bitmaps MAY limit the portability of the metafile to other devices. For instance, display device contexts generally do not support this pass-through.
BI_CMYK
public static final int BI_CMYK
The image is an uncompressed CMYK format.
BI_CMYKRLE8
public static final int BI_CMYKRLE8
A CMYK format that uses RLE compression for bitmaps with 8 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by a byte containing a color index.
BI_CMYKRLE4
public static final int BI_CMYKRLE4
A CMYK format that uses RLE compression for bitmaps with 4 bits per pixel. The compression uses a 2-byte format consisting of a count byte followed by two word-length color indexes.
