SmallCapsSize

Represents constant SmallCapsSize. (Inherited from RSSVG.Text.TSVGCustomText.)

SpaceSubstitute

Represents constant SpaceSubstitute. (Inherited from RSSVG.Text.TSVGCustomText.)

Create(TSVGDocument)

Initializes a new instance of the TSVGCustomText class. (Overrides RSSVG.TSVGGraphicElement.Create(TSVGDocument).)

AlignmentBaseline

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. It defaults to the baseline with the same name as the computed value of the alignment-baseline property. That is, the position of "ideographic" alignment-point in the block-progression-direction is the position of the "ideographic" baseline in the baseline-table of the object being aligned.

Attributes

Returns the valid style properties of the svg element (Inherited from RSSVG.TSVGElement.)

BaselineShift

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.

BoundsRect

Specifies the bounding rectangle (X, Y, X+Width, Y+Height) for the SVG element unmodified by any transformations in the current coordinate system.

The X, Y, Width, and Height properties specify coordinates in virtual pixels of the nearest viewbox, or coordinate system. For example, a TSVGDocument may specify a ViewBox of 0, 0, 100, 100. Specifying an element's X and Y as 50, 50 will always position the element to start in the exact center of the view box. If the TSVGDocument is then drawn to a true pixel rectangle of 1000 pixel width and 500 pixel height, the element would draw at 500, 250 pixels.

To retrieve the "true" bounding rectangle which has been modified by any transformations, use the GetBoundsRect method

The BoundsRect and X/Y/Width/Height properties specify coordinates in virtual pixels of the nearest viewbox, or coordinate system. For example, a TSVGDocument may specify a ViewBox of 0, 0, 100, 100. Specifying an element's X and Y as 50, 50 will always position the element to start in the exact center of the view box. If the TSVGDocument is then drawn to a true pixel rectangle of 1000 pixel width and 500 pixel height, the element would draw at 500, 250 pixels.

Brush

Brush used for drawing the fill portions of the SVG element (Inherited from RSSVG.TSVGGraphicElement.)

BrushChanged

Specifies whether the Brush has been changed and needs to be reinitializated by the GetBrush method. Set this property to true to force initialization of the Brush for the current SVG element. (Inherited from RSSVG.TSVGGraphicElement.)

Classes

Specifies the 'classes' that the SVG element belongs to. The classes property assigns one or more class names to an element. The element may be said to belong to these classes. A class name may be shared by several element instances. (Inherited from RSSVG.TSVGElement.)

ClippingChanged

Specifies whether the Clipping has been changed and needs to be reinitializated by the GetClipping method. Set this property to false to force initialization of the Clipping for the current SVG element. (Inherited from RSSVG.TSVGGraphicElement.)

ClipRect

Returns the clipping rectangle for the element (Inherited from RSSVG.TSVGGraphicElement.)

ClipRule

Clipping rule for how this element adds to the clipping path (Inherited from RSSVG.TSVGGraphicElement.)

ClipURI

ID of the SVG element that provides the clipping region (Inherited from RSSVG.TSVGGraphicElement.)

ClipURIElement

Returns the SVG element that provides the clipping region for the current element.

The ClipURI property specifies the ID of the SVG element that provides the clipping region

Color

Color used for provide a potential indirect value (currentColor) for the ‘fill’, ‘stroke’, ‘stop-color’, ‘flood-color’ and ‘lighting-color’ properties (Inherited from RSSVG.TSVGGraphicElement.)

ColorInterpolation

Color interpolation type, which specifies the color space for gradient interpolations and alpha compositing

VCL Only

ColorRendering

VCL Only

CurrentTextIndex

Returns the index into the Text property of the current text element and all of its childrens' text together. (Inherited from RSSVG.Text.TSVGCustomText.)

CurrentTextPosition

Returns the current position to place the next character in the text (Inherited from RSSVG.Text.TSVGCustomText.)

Cursor

Cursor to use when over this element type (Inherited from RSSVG.TSVGGraphicElement.)

Description

Specifies a non-visual Description for the SVG element. When generating FMX controls, the FMX control's Hint property is set to the Description. If the Description is empty, the Hint is set to the Title (Inherited from RSSVG.TSVGElement.)

Direction

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.

Within text content elements, the alignment of text with regards to the ‘text-anchor’ property is determined by the value of the ‘direction’ property. For example, given a ‘text’ element with a ‘text-anchor’ value of "end", for a ‘direction’ value of "ltr", the text will extend to the left of the position of the ‘text’ element's ‘x’ attribute value, while for ‘direction’ value of "rtl", the text will extend to the right of the position of the ‘text’ element's ‘x’ attribute value.

DominantBaseline

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.

DX

Specifies the list of relative x-axis coordinates for each character in the text.

If a single <length> is provided, this value represents the new relative X coordinate for the current text position for rendering the glyphs corresponding to the first character within this element or any of its descendants. The current text position is shifted along the x-axis of the current user coordinate system by <length> before the first character's glyphs are rendered.

If a comma- or space-separated list of n <length>s is provided, then the values represent incremental shifts along the x-axis for the current text position before rendering the glyphs corresponding to the first n characters within this element or any of its descendants. Thus, before the glyphs are rendered corresponding to each character, the current text position resulting from drawing the glyphs for the previous character within the current ‘text’ element is shifted along the X axis of the current user coordinate system by <length>.

If more <length>s are provided than characters, then any extra <length>s will have no effect on glyph positioning.

If more characters exist than <length>s, then for each of these extra characters: (a) if an ancestor ‘text’ or ‘tspan’ element specifies a relative X coordinate for the given character via a ‘dx’ attribute, then the current text position is shifted along the x-axis of the current user coordinate system by that amount (nearest ancestor has precedence), else (b) no extra shift along the x-axis occurs.

If the attribute is not specified: (a) if an ancestor ‘text’ or ‘tspan’ element specifies a relative X coordinate for a given character via a ‘dx’ attribute, then the current text position is shifted along the x-axis of the current user coordinate system by that amount (nearest ancestor has precedence), else (b) no extra shift along the x-axis occurs.

DXStr

Provides a string representation of the RSSVG.Text.TSVGCustomText.DX array property (Inherited from RSSVG.Text.TSVGCustomText.)

DY

Specifies the list of relative y-axis coordinates for each character in the text.

The processing rules for the DY property parallel the processing rules for the RSSVG.Text.TSVGCustomText.DY property.

DYStr

Provides a string representation of the RSSVG.Text.TSVGCustomText.DY array property (Inherited from RSSVG.Text.TSVGCustomText.)

ElementState

Returns the state of the element. Use this property to correctly update the element when it is in a certain state. (Inherited from RSSVG.TSVGElement.)

Enabled

Specifies whether the element is enabled or disabled. By default, disabled elements are not exported or detected by the RSSVG.TSVGElement.ElementAtPos(TSVGCanvas,TSVGPoint,TSVGRect,TSVGFindOptions) method.

Disabled elements are shown using a grayscale version of the element, which may be overridden with the OnDisableAppearance event.

FillRule

Indicates the algorithm which is to be used to determine what parts of the canvas are included inside the element 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. (Inherited from RSSVG.TSVGGraphicElement.)

Font

Font used for drawing the Text portions of the SVG element (Inherited from RSSVG.TSVGGraphicElement.)

FontChanged

Specifies whether the Font has been changed and needs to be reinitializated by the GetFont method. Set this property to false to force initialization of the Font for the current SVG element. (Inherited from RSSVG.TSVGGraphicElement.)

GlyphOrientationHorizontal

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.

This property is applied only to text written in a horizontal RSSVG.TSVGGraphicElement.WritingMode .

GlyphOrientationVertical

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.

This property is applied only to text written in a vertical RSSVG.TSVGGraphicElement.WritingMode

Height

Height of the element in the current user coordinate system

The X, Y, Width, and Height properties specify coordinates in virtual pixels of the nearest viewbox, or coordinate system. For example, a TSVGDocument may specify a ViewBox of 0, 0, 100, 100. Specifying an element's X and Y as 50, 50 will always position the element to start in the exact center of the view box. If the TSVGDocument is then drawn to a true pixel rectangle of 1000 pixel width and 500 pixel height, the element would draw at 500, 250 pixels.

HeightU

Height of the element in the current user coordinate system.

The property is a length with raw measurement value and its units (e.g., 1 inch, 2.5 centimeters, etc). When the element needs to get the x-axis coordinate in pixels, this property converts the raw measurement value using the RSSVG.TSVGGraphicElement.GetUnitFactors (e.g., 1 inch = 96 pixels) .

The Xu, Yu, WidthU, and HeightU properties specify coordinates in virtual pixels of the nearest viewbox, or coordinate system. For example, a TSVGDocument may specify a ViewBox of 0, 0, 100, 100. Specifying an element's X and Y as 50, 50 will always position the element to start in the exact center of the view box. If the TSVGDocument is then drawn to a true pixel rectangle of 1000 pixel width and 500 pixel height, the element would draw at 500, 250 pixels.

ID

OpacityPreferredUnit

Provides the unit type (e.g., mm, px, etc) to use when displaying the Opacity (Inherited from RSSVG.TSVGGraphicElement.)

Options

Defines options for reading, displaying, and writing the svg.

The most important option as far as compatibility is the soUseFillText option. When this option is present, the RSCL uses FillText calls to directly render the text to the canvas. When this option is not present (default), the RSCL converts text into paths that are then filled and stroked. Converting text to paths provides the highest compatibility but slower performance. If you use the FMX GPU Canvas (FMX.Types.GlobalUseGPUCanvas), text is always filled and not converted to paths.

The following differences exist between the two text rendering paths:

• Fill Text does not use the Pen and so cannot both fill and stroke text

• Fill Text cannot use gradients for filling (FMX)

•ShapeRendering affects the smoothness of text when filling path-based text (as text are shapes); TextRendering affects the smoothness of text when filling text

• Fill Text uses less memory

• Fill Text generates better text at small sizes

• Path-based text caches its shapes so subsequent draw calls are faster, even faster than fill text calls in many cases

• Path-based text allows pixel level selection of text; Fill Text can only be selected as a text bounding box

• Path-based text renders decorative fonts (underline, overline, and strike-out) using an extra path for the decoration (FMX will not generate paths with the decoration when converting text to paths). Surprisingly, this means that compatibility is higher with path-based text as the decoration gets its rendering configuration from the parent text element (e.g., strike-out text should use the parent text's font size and not vary as the size of child text span's font size changes).

AlignText(TSVGCustomText,TSVGShapePath,TSVGRect,TSVGPoint)

Aligns (start, middle, end) the text shape in the Line parameter (a string of character shapes) within the TextR rectangle. The TextPadding parameter controls the amount of padding, or margin, to leave within the TextR rectangle.
