Class CTParagraphStyleSpecifier

  • public final class CTParagraphStyleSpecifier
extends java.lang.Object
    [@enum] CTParagraphStyleSpecifier These constants are used to query and modify the CTParagraphStyle object. Each specifier has a type and a default value associated with it. The type must always be observed when setting or fetching the value from the CTParagraphStyle object. In addition, some specifiers affect the behavior of both the framesetter and the typesetter, and others only affect the behavior of the framesetter; this is also noted below. [@constant] kCTParagraphStyleSpecifierAlignment The text alignment. Natural text alignment is realized as left or right alignment, depending on the line sweep direction of the first script contained in the paragraph. Type: CTTextAlignment Default: kCTTextAlignmentNatural Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierFirstLineHeadIndent The distance in points from the leading margin of a frame to the beginning of the paragraph's first line. This value is always nonnegative. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierHeadIndent The distance in points from the leading margin of a text container to the beginning of lines other than the first. This value is always nonnegative. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierTailIndent The distance in points from the margin of a frame to the end of lines. If positive, this value is the distance from the leading margin (for example, the left margin in left-to-right text). If 0 or negative, it's the distance from the trailing margin. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierTabStops The CTTextTab objects, sorted by location, that define the tab stops for the paragraph style. Type: CFArray of CTTextTabRef Default: 12 left-aligned tabs, spaced by 28.0 points Application: CTFramesetter, CTTypesetter [@constant] kCTParagraphStyleSpecifierDefaultTabInterval The document-wide default tab interval. Tabs after the last specified by kCTParagraphStyleSpecifierTabStops are placed at integer multiples of this distance (if positive). Type: CGFloat Default: 0.0 Application: CTFramesetter, CTTypesetter [@constant] kCTParagraphStyleSpecifierLineBreakMode The mode that should be used to break lines when laying out the paragraph's text. Type: CTLineBreakMode Default: kCTLineBreakByWordWrapping Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierLineHeightMultiple The line height multiple. The natural line height of the receiver is multiplied by this factor (if positive) before being constrained by minimum and maximum line height. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierMaximumLineHeight The maximum height that any line in the frame will occupy, regardless of the font size or size of any attached graphic. Glyphs and graphics exceeding this height will overlap neighboring lines. A maximum height of 0 implies no line height limit. This value is always nonnegative. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierMinimumLineHeight The minimum height that any line in the frame will occupy, regardless of the font size or size of any attached graphic. This value is always nonnegative. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierLineSpacing Deprecated. Use kCTParagraphStyleSpecifierMaximumLineSpacing, kCTParagraphStyleSpecifierMinimumLineSpacing, and kCTParagraphStyleSpecifierLineSpacingAdjustment to control space between lines. [@constant] kCTParagraphStyleSpecifierParagraphSpacing The space added at the end of the paragraph to separate it from the following paragraph. This value is always nonnegative and is determined by adding the previous paragraph's kCTParagraphStyleSpecifierParagraphSpacing setting and the current paragraph's kCTParagraphStyleSpecifierParagraphSpacingBefore setting. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierParagraphSpacingBefore The distance between the paragraph's top and the beginning of its text content. Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierBaseWritingDirection The base writing direction of the lines. Type: CTWritingDirection Default: kCTWritingDirectionNatural Application: CTFramesetter, CTTypesetter [@constant] kCTParagraphStyleSpecifierMaximumLineSpacing The maximum space in points between lines within the paragraph (commonly known as leading). Type: CGFloat Default: some large number. Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierMinimumLineSpacing The minimum space in points between lines within the paragraph (commonly known as leading). Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierLineSpacingAdjustment The space in points added between lines within the paragraph (commonly known as leading). Type: CGFloat Default: 0.0 Application: CTFramesetter [@constant] kCTParagraphStyleSpecifierLineBoundsOptions The options controlling the alignment of the line edges with the leading and trailing margins. Type: CTLineBoundsOptions Default: 0 (no options) Application: CTTypesetter
