ESVGException

Base exception class for the RiverSoftAVG SVG Component Library

TSVGBaselineShiftLength

Extends the RSSVGTypes.TSVGStylePropertyLength class for the baseline shift style property. It inherits all the features of TSVGStylePropertyLength and adds the RSSVGTypes.TSVGBaselineShiftLength.Shift property.

TSVGBrush

Provides the SVG TBrush class. TSVGBrush is used to fill solid shapes, such as rectangles and ellipses, with a color or pattern. The Kind property controls the mode in which a TSVGBrush instance operates.

The URI property stores a reference to another SVG element for providing the pattern or gradient for the brush.

TSVGFont

Provides the SVG font class

TSVGLength

Defines the SVG Length type, including its Raw value, Unit, and whether it is a percentage. The RSSVGTypes.TSVGLength.Raw value represents the length in the current unit (e.g., inch, centimeter, etc); the RSSVGTypes.TSVGLength.Pixels and RSSVGTypes.TSVGLength.Value properties display the length converted to pixels. This allows you to set the length to 2 inches. Then, depending on what the RSSVGTypes.TSVGLength.GetUnitFactors method returns for pixels per inch, the Pixels property can change.

In SVGs, a length is a distance measurement, given as a number along with a unit which may be optional. Lengths are specified in one of two ways depending upon whether they are used in CSS property syntax or SVG presentation attribute syntax:

• When a <length> is used in a style sheet or with a property in a ‘style’ attribute, the syntax must match the following pattern:
 
length ::= number (~"em" | ~"ex" | ~"px" | ~"in" | ~"cm" | ~"mm" | ~"pt" | ~"pc")?
See the CSS2 specification for the meanings of the unit identifiers. The unit identifier may be in lower (recommended) or upper case.
 
For properties defined in CSS2 [CSS2], a length unit identifier must be provided (for non-zero values). For SVG-specific properties, the length unit identifier is optional. If a unit is not provided, the length value represents a distance in the current user coordinate system.

TSVGSelectorToken

Defines one CSS2 token created by the TokenizeSelector function

ISVGViewer

Defines a SVG Viewer interface. A class implements the ISVGViewer interface to indicate that it is interested in SVG changes (which could change the graphic) and wants to be able to respond.

RSSVGTypes.

Represents type .

TExtendedFontStyle

Defines extended font styles for the TSVGFont class

fsBlink is not supported by the RSCL.

TSVGAlign

Defines the SVG align type, which specifies the alignment of the SVG document or viewport within a parent.

TSVGAlignmentBaseline

Specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes.

TSVGBaselineShift

Allows repositioning of the dominant-baseline relative to the dominant-baseline of the parent text content element. The shifted object might be a sub- or superscript. Within the shifted object, the whole baseline-table is offset; not just a single baseline. The amount of the shift is determined from information from the parent text content element, the sub- or superscript offset from the nominal font of the parent text content element, percent of the "line-height" of the parent text content element or an absolute value.

TSVGColorInterpolation

Defines the SVG color interpolation type, which specifies the color space for gradient interpolations and alpha compositing.

TSVGColorRendering

Defines the SVG color rendering type, which provides a hint to the SVG library about how to optimize its color interpolation and compositing operations.

TSVGCoordinateSystemUnit

Defines the SVG unit type, which defines the coordinate system for other SVG attributes.

TSVGCursor

Defines the SVG curstor type, which specifies the type of cursor to be displayed when over the SVG element

TSVGDirection

Specifies the base writing direction of text

The ‘direction’ property applies only to glyphs oriented perpendicular to the inline-progression-direction, which includes the usual case of horizontally-oriented Latin or Arabic text and the case of narrow-cell Latin or Arabic characters rotated 90 degrees clockwise relative to a top-to-bottom inline-progression-direction

TSVGDominantBaseline

The "dominant-baseline" property is used to determine or re-determine a scaled-baseline-table. A scaled-baseline-table is a compound value with three components: a baseline-identifier for the dominant-baseline, a baseline-table and a baseline-table font-size. Some values of the property re-determine all three values; other only re-establish the baseline-table font-size. When the initial value, auto, would give an undesired result, this property can be used to explicitly set the desire scaled-baseline-table.

TSVGElementType

Defines the different SVG element types in an SVG document and can be created by the SVG library

TSVGFeature

Defines the features for the SVG ‘requiredFeatures’ attribute. In some cases the features map directly to a set of attributes, properties or elements, in others they represent some functionality of the user agent (that it is a dynamic viewer for example)

TSVGFillRule

Defines the SVG fill rule type, which indicates the algorithm which is to be used to determine what parts of the canvas are included inside the shape. For a simple, non-intersecting path, it is intuitively clear what region lies "inside"; however, for a more complex path, such as a path that intersects itself or where one subpath encloses another, the interpretation of "inside" is not so obvious.

TSVGFindOption

TSVGFontStyle

Defines the SVG font variants type, which specifies the rendering of text as normal text or with different case

TSVGFontWeight

Defines the font weight type for the SVG 'font-weight' attribute, e.g., the boldness or lightness of the glyphs used to render the text, relative to other fonts in the same font family

TSVGGenericFontFamily

Defines the generic font families. The generic font family are used if one or more of the other fonts in a font set is unavailable when defining the font-family of a text element. The following generic families are defined: 'serif', 'sans-serif', ' cursive', 'fantasy', and 'monospace'

TSVGGlyphOrientationHorizontal

In some cases, it is required to alter the orientation of a sequence of characters relative to the inline-progression-direction. The requirement is particularly applicable to vertical layouts of East Asian documents, where sometimes narrow-cell Latin text is to be displayed horizontally and other times vertically.
 
Two properties control the glyph orientation relative to the reference orientation for each of the two possible inline-progression-directions. ‘glyph-orientation-vertical’ controls glyph orientation when the inline-progression-direction is vertical. ‘glyph-orientation-horizontal’ controls glyph orientation when the inline-progression-direction is horizontal.

TSVGGlyphOrientationVertical

In some cases, it is required to alter the orientation of a sequence of characters relative to the inline-progression-direction. The requirement is particularly applicable to vertical layouts of East Asian documents, where sometimes narrow-cell Latin text is to be displayed horizontally and other times vertically.
 
Two properties control the glyph orientation relative to the reference orientation for each of the two possible inline-progression-directions. ‘glyph-orientation-vertical’ controls glyph orientation when the inline-progression-direction is vertical. ‘glyph-orientation-horizontal’ controls glyph orientation when the inline-progression-direction is horizontal.

TSVGUnit

Defines the SVG unit type, which specifies the different units of measurement that can be specified for a SVG length

TSVGVectorEffect

Defines the SVGTiny vector effect type. Sometimes it is of interest to let the outline of an object keep its original width no matter which transforms are applied to it. For example, in a map with a 2px wide line representing roads it is of interest to keep the roads 2px wide even when the user zooms into the map. To achieve this, SVG Tiny 1.2 introduces the 'vector-effect' property. Future versions of the SVG language may allow for more powerful vector effects through this property.

TSVGWritingMode

Specifies whether the initial inline-progression-direction for a ‘text’ element shall be left-to-right, right-to-left, or top-to-bottom. The ‘writing-mode’ property applies only to ‘text’ elements; the property is ignored for ‘tspan’, ‘tref’, ‘altGlyph’ and ‘textPath’ sub-elements.
