Enclosing class:

XFSDataTypes

public static final class XFSDataTypes.BITMAPFORMAT

extends XFSDataTypes.CARD32

This structure specifies how glyph images are transmitted in response to QueryXBitmaps8 and QueryXBitmaps16 requests. CARD32 containing the following fields defined by the sets of values given further below.
All unspecified bits must be zero.
Use of an invalid BITMAPFORMAT causes a Format error to be returned.

BITMAPFORMAT: CARD32

NB:BITMAPFORMAT is represented internally as a Java long.

Field Summary

static int	BitOrderMSB If the BIT-ORDER-MSB bit is set, the left-most bit in each glyph scanline unit is stored in the Most Significant Bit of each transmitted scanline unit.
static int	ByteOrderMSB If the BYTE-ORDER-MSB bit is set, the Most Significant Byte of each scanline unit is returned first.
static int	ImageRectMax This refers to all scanlines, from the maximum ascent (or the font ascent, whichever is greater) to the maximum descent (or the font descent, whichever is greater), padded to the same horizontal extents as MaxWidth.
static int	ImageRectMaxWidth This refers to the scanlines between the glyph s ascent and descent, padded on the left to the minimum left-bearing (or 0, whichever is less) and on the right to the maximum right-bearing (or logical-width, whichever is greater).
static int	ImageRectMin This refers to the minimal bounding rectangle surrounding the inked pixels in the glyph.
static int	ScanlinePad16 The SCANLINE-PAD field specifies the number of bits (8, 16, 32, or 64) to which each glyph scanline is padded before transmitting.
static int	ScanlinePad32 The SCANLINE-PAD field specifies the number of bits (8, 16, 32, or 64) to which each glyph scanline is padded before transmitting.
static int	ScanlinePad64 The SCANLINE-PAD field specifies the number of bits (8, 16, 32, or 64) to which each glyph scanline is padded before transmitting.
static int	ScanlinePad8 The SCANLINE-PAD field specifies the number of bits (8, 16, 32, or 64) to which each glyph scanline is padded before transmitting.
static int	ScanlineUnit16 The SCANLINE-UNIT field specifies the number of bits (8, 16, 32, or 64) that should be treated as a unit for swapping.
static int	ScanlineUnit32 The SCANLINE-UNIT field specifies the number of bits (8, 16, 32, or 64) that should be treated as a unit for swapping.
static int	ScanlineUnit64 The SCANLINE-UNIT field specifies the number of bits (8, 16, 32, or 64) that should be treated as a unit for swapping.
static int	ScanlineUnit8 The SCANLINE-UNIT field specifies the number of bits (8, 16, 32, or 64) that should be treated as a unit for swapping.

Field Detail

BitOrderMSB

public static final int BitOrderMSB

If the BIT-ORDER-MSB bit is set, the left-most bit in each glyph scanline unit is stored in the Most Significant Bit of each transmitted scanline unit. Otherwise, the left-most bit is stored in the Least Significant Bit.

Constant Field Values

ByteOrderMSB

public static final int ByteOrderMSB

If the BYTE-ORDER-MSB bit is set, the Most Significant Byte of each scanline unit is returned first. Otherwise, the Least Significant Byte is returned first.

Constant Field Values

ImageRectMax

public static final int ImageRectMax

This refers to all scanlines, from the maximum ascent (or the font ascent, whichever is greater) to the maximum descent (or the font descent, whichever is greater), padded to the same horizontal extents as MaxWidth. The IMAGE-RECT field specifies a rectangle of pixels within the glyph image.
For a glyph with extents XCHARINFO in a font with header information XFONTINFO, the IMAGE-RECT values have the following meaning:

ImageRectMax: All glyph images have the same sized bitmap and share a common origin. This is the least compact representation, but may be the easiest or most efficient (particularly for character cell fonts) for some clients to use. The edges of the rectangle are:

left	min (XFONTINFO.MIN-BOUNDS.LBEARING, 0)
right	max (XFONTINFO.MAX-BOUNDS.RBEARING, XFONTINFO.MAX-BOUNDS.WIDTH)
top	max (XFONTINFO.FONT-ASCENT, XFONTINFO.MAX-BOUNDS.ASCENT)
bottom	max (XFONTINFO.FONT-DESCENT, XFONTINFO.MAX-BOUNDS.DESCENT)

Constant Field Values

ImageRectMaxWidth

public static final int ImageRectMaxWidth

This refers to the scanlines between the glyph s ascent and descent, padded on the left to the minimum left-bearing (or 0, whichever is less) and on the right to the maximum right-bearing (or logical-width, whichever is greater). The IMAGE-RECT field specifies a rectangle of pixels within the glyph image.
For a glyph with extents XCHARINFO in a font with header information XFONTINFO, the IMAGE-RECT values have the following meaning:

ImageRectMaxWidth: All glyph images share a common horizontal origin. This is a combination of ImageRectMax in the horizontal direction and ImageRectMin in the vertical direction. The edges of the rectangle are:

left	min (XFONTINFO.MIN-BOUNDS.LBEARING, 0)
right	max (XFONTINFO.MAX-BOUNDS.RBEARING, XFONTINFO.MAX-BOUNDS.WIDTH)
top	XCHARINFO.ASCENT
bottom	XCHARINFO.DESCENT

See Also:

Constant Field Values

ImageRectMin

public static final int ImageRectMin

This refers to the minimal bounding rectangle surrounding the inked pixels in the glyph. The IMAGE-RECT field specifies a rectangle of pixels within the glyph image.
For a glyph with extents XCHARINFO in a font with header information XFONTINFO, the IMAGE-RECT values have the following meaning:

ImageRectMin: This is the most compact representation. The edges of the rectangle are:

left	XCHARINFO.LBEARING
right	XCHARINFO.RBEARING
top	XCHARINFO.ASCENT
bottom	XCHARINFO.DESCENT

ScanlinePad16

ScanlinePad32

public static final int ScanlinePad32

The SCANLINE-PAD field specifies the number of bits (8, 16, 32, or 64) to which each glyph scanline is padded before transmitting.

ScanlineUnit32

public static final int ScanlineUnit32

The SCANLINE-UNIT field specifies the number of bits (8, 16, 32, or 64) that should be treated as a unit for swapping. This value must be less than or equal to the number of bits specified by the SCANLINE-PAD.
