Field Detail

EOF

static final int EOF

Basic theory: Rover is streaming vector graphic data consisting of chunks containing the same type and style of data. Each chunk is announced by an type code and flags, which tell you the format of the contents. This is followed by a count of the number of items in the contents. Finally the contents themselves are given.

HAS_DATA

static final int HAS_DATA

Indicates that the data includes a UInt32 data ID.

See Also:

Constant Field Values

HAS_OFFSET

static final int HAS_OFFSET

Indicates that the data includes Int8 x and y pixel offsets. Currently only has meaning for points and text but lines could conceivably have it too.

See Also:

Constant Field Values

HAS_ROTATION

static final int HAS_ROTATION

Indicates that the data includes an Int8 rotation (expressed as signed units representing 1/256 of a circle; zero is due east (positive X axis). Only has meaning for points and text; could be reused for some other purpose for lines.

Constant Field Values

FLOAT_COORDS

static final int FLOAT_COORDS

Indicates that the xy coordinates are given as Float values rather than the default UInt8 texel coordinates.

See Also:

Constant Field Values

ROTATION_MULT

static final float ROTATION_MULT

Converts from UInt8 rotation format to floating point radians.

See Also:

Constant Field Values

TEXEL_COORD_MAX

static final int TEXEL_COORD_MAX

The maximum size of a texel coordinate.

See Also:

Constant Field Values

TILE_COORD_MAX

static final int TILE_COORD_MAX

The maximum size of a tile coordinate. Currently using unsigned shorts.

See Also:

Constant Field Values

TILE_SIZE_PIXELS

static final int TILE_SIZE_PIXELS

This is multiplied by the minimum scale to get a tile size. For 8-bit texels, it should be 256; for 16-bits it shouldn't be 65536 because the tiles get humongous. 4096 is probably right for 16-bit texels; that gives the Palm decent numbers to work with and some extra resolution for the desktop.
