struct FontMetrics

Description: Metrics global to the font, i.e. not specific to single +glyphs. The font height is defined as +ascent+descent+internalLeading, and therefore not explicitely +included here.; + +Please note that when querying FontMetrics from an XCanvasFont +interface, all values here are given relative to the font cell +size. That means, the referenceCharWidth and/or +ascent+descent+internalLeading will approximately (rounded to +integer device resolution, or exactly, if fractional font +rendering is enabled) match the referenceAdvancement/cellSize +members of the FontRequest for which the XCanvasFont was +queried. Please be aware that the values returned in this +structure only map one-to-one to device pixel, if the combined +rendering transformation for text output equals the identity +transformation. Otherwise, the text output (and thus the resulting +metrics) will be subject to that transformation. Depending on the +underlying font technology, actual device output might be off by +up to one device pixel from the transformed metrics. + +
Since: OOo 2.0.0

Elements' Summary
Ascent	Ascent (above the baseline) part of the font.
Descent	Descent (below the baseline) part of the font.
InternalLeading	Extra space above ascent
ExternalLeading	Extra space outside the font cells.
ReferenceCharSize	This value specifies the reference character width of the +font.
UnderlineOffset	Specifies the offset to be added to the baseline when drawing +underlined text. +
StrikeThroughOffset	Specifies the offset to be added to the baseline when striking +through the text. +

Ascent + + + + +

double Ascent; + + Description + Ascent (above the baseline) part of the font. + +

Descent + + + + +

double Descent; + + Description + Descent (below the baseline) part of the font. + +

InternalLeading + + + + +

double InternalLeading; + + Description + Extra space above ascent + +

ExternalLeading + + + + +

double ExternalLeading; + + Description + Extra space outside the font cells. + + +It should not contain ink marks and is typically used +by the font designer to modify the line distance. + + +

ReferenceCharSize + + + + +

double ReferenceCharSize; + + Description + This value specifies the reference character width of the +font. + + +It's roughly equivalent to the average width of all +characters, and if one needs a font with double character +width, the referenceCharSize should be doubled. + + +

UnderlineOffset + + + + +

double UnderlineOffset; + + Description + Specifies the offset to be added to the baseline when drawing +underlined text. + + +

StrikeThroughOffset + + + + +

double StrikeThroughOffset; + + Description + Specifies the offset to be added to the baseline when striking +through the text. + + +

Elements' Summary
FontDescription	The PANOSE font classification.
FamilyName	The name of the font family.
StyleName	The name of the specific font style within its family.
IsSymbolFont	This value specifies which unicode ranges are supported by +this font.
IsVertical	Set to true, if the font is usable for vertical text +output.

Elements' Summary
FontDescription	The description of the font.
CellSize	The size of the font in device coordinate space.
ReferenceAdvancement	This value specifies the size of the font in the writing +direction (i.e. width for horizontal writing, and height for +vertical writing).
Locale	The locale this font should be able to render.

Constants
CHUNKY_1BIT	One bit format, with chunky layout. +
PLANES_1BIT	One bit format, with plane layout. +
CHUNKY_2BIT	Two bit format, with chunky layout. +
PLANES_2BIT	Two bit format, with plane layout. +

ColorSpace	Color space the bitmap colors shall be interpreted within.
NumComponents	Number of color components per pixel. + +This value must not be negative +
ComponentMasks	Mask values for packed bitmaps + +This member contains NumComponents 64 bit masks, which can be +used to mask out the corresponding color component from the +bitmap data. For the typical 32 bit RGBA color data, the four +mask values would look like 0xFF000000, 0x00FF0000, +0x0000FF00, and 0x000000FF. +
Palette	This member determines whether the bitmap data are actually +indices into a color map.
Endianness	Endianness of the pixel values. + +This value must be one of the Endianness constants +
Format	Format type of this bitmap.
IsMsbFirst	This member determines the bit order (only relevant if a pixel +uses less than 8 bits, of course).

Constants
NEAREST_NEIGHBOR	Perform a nearest neighbor interpolation.
