Constructor Detail

LayoutDriver

public LayoutDriver()

Default c'tor

LayoutDriver

public LayoutDriver(LayoutEnv oEnv)

Constructor, creates an LayoutDriver object.

Method Detail

setLayoutEnv

public void setLayoutEnv(LayoutEnv oEnv)

Set the gfx environment

absLine

public void absLine(CoordPair oEnd,
                    int eDrawMode)

Specified by:

absLine in class GFXDriver

absFillRect

public void absFillRect(Rect oRect,
                        int eDrawMode)

Specified by:

absFillRect in class GFXDriver

absText

public void absText(String oText,
                    int eDrawMode)

Specified by:

absText in class GFXDriver

absGlyphs

public void absGlyphs(int[] nGlyphs,
                      int nSize)

Overrides:

absGlyphs in class GFXDriver

setUnicodeChars

public void setUnicodeChars(String text,
                            int nSize)

mapGlyphs

public void mapGlyphs(GFXMappingList mappingList,
                      boolean bIsRTL)

Description copied from class: GFXDriver

Full character/glyph mapping.

If the driver needs legacy mapping, the caller must preceed each call to a text rendering method with a call to this method. Full mapping supports 1:1, N:1, 1:M and N:M mappings, as well as mappings that involve non-contiguous runs of Unicode content and glyph output.

Overrides:

mapGlyphs in class GFXDriver

Parameters:

mappingList - - Description of the mappings for the subsequent text rendering call. The Unicode character indexes in the mappings are relative to the line's text passed in SetUnicodeChars(). The glyph indexes are zero-based, relative to the glyphs in the next text rendering call.

bIsRTL - - True if the subsequent run represents RTL text; FALSE for LTR text.

getMappingLevel

public int getMappingLevel()

Description copied from class: GFXDriver

Return the mapping required by the driver.

Overrides:

getMappingLevel in class GFXDriver

Returns:

Mapping level that the client must implement in order to satisfy the driver's needs.

setMappingLevel

public void setMappingLevel(int nSLevel)

height

public int height()

Specified by:

height in class GFXDriver

width

public int width()

Specified by:

width in class GFXDriver

interactive

public boolean interactive()

Specified by:

interactive in class GFXDriver

setClipRect

public void setClipRect(Rect oRect)

paraHint

public void paraHint()

Overrides:

paraHint in class GFXDriver
