public final class WmfCompression extends System.Enum

The Compression Enumeration specifies the type of compression for a bitmap image

Fields

FieldDescription
BI_RGBThe bitmap is in uncompressed red green blue (RGB) format that is not compressed and does not use color masks.
BI_RLE8An RGB format that uses run-length encoding (RLE) compression for bitmaps with 8 bits per pixel.
BI_RLE4An RGB format that uses RLE compression for bitmaps with 4 bits per pixel.
BI_BITFIELDSThe 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_JPEGThe image is a JPEG image, as specified in [JFIF].
BI_PNGThe image is a PNG image, as specified in [RFC2083].
BI_CMYKThe image is an uncompressed CMYK format.
BI_CMYKRLE8A CMYK format that uses RLE compression for bitmaps with 8 bits per pixel.
BI_CMYKRLE4A 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.
