Enumeration Type Documentation

enum SLComposerStatusCode

Status codes used internally by the composer. Status codes greater or equal to kCompSuccess are good, less than kCompSuccess are bad. So tests for status like if (status < kCompSuccess) error are used.

Enumerator
kCompIncompatibleCharacter	The character cannot be added into a GlyphNode.
kCompChangeOfHeight	The maximum height we have tiles for has been exceeded.
kCompWillNotFit	Cannot fit characters in the current set of tiles.
kCompOutOfMemory	Memory allocation failure.
kCompFailure	Unexpected error, nil interface pointer
kCompSuccess	Success
kCompEndOfLine	End of line detected.
kCompStop	Composition stopped before end of line. A table character, kTextChar_Table, or similar has been detected. All we have to do is stop, leave the character alone and the application will compose the table.

Function Documentation

const PMReal kSLCGridAlignmentMetricOffset

(

0.

0

)

Offset is always zero for baseline grid or no alignment. Note alignment to the baseline grid is done by the tiler. If we ask for tiles aligned to the baseline grid then we'll get them. The tiler figures out where they should be.

Variable Documentation

const Text::LeadingModel kSLCLeadingModel = Text::kRomanLeadingModel

This composer implements a roman leading model (the distance between the baselines of consecutive lines of text is set to the maximum leading value on the line being composed).

const Text::FirstLineOffsetMetric kSLCLineHeightMetric = Text::kFLOLeading

Maximum leading value on the line is used to set the line height.
