Base class for container elements in the RSCL

Namespace: FMX.RS.SVG

Name

Description

published property

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.

Note
Currently, only auto/baseline is supported

public property

Attributes

Returns the valid style properties of the svg element (Inherited from FMX.RS.SVG.TSVGElement.)

published property

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.

Note
‘baseline-shift’ properties can nest. Each nested ‘baseline-shift’ is added to previous baseline shift values.

public property

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.

Note
Note that this property is before any transformation (i.e., Matrix property) is applied

published property

Brush

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

protected property

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 FMX.RS.SVG.TSVGGraphicElement.)

protected property

CalcBR

Represents property CalcBR.

published property

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 FMX.RS.SVG.TSVGElement.)

protected property

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 FMX.RS.SVG.TSVGGraphicElement.)

public property

ClipRect

Returns the clipping rectangle for the element (Inherited from FMX.RS.SVG.TSVGGraphicElement.)

published property

ClipRule

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

published property

ClipURI

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

public property

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

published property

Color

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

published property

ColorInterpolation

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

VCL Only

published property

ColorRendering

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

VCL Only

published property

Cursor

Cursor to use when over this element type (Inherited from FMX.RS.SVG.TSVGGraphicElement.)

published property

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 FMX.RS.SVG.TSVGElement.)

published property

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.

published property

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.

Note
Not supported

public property

ElementState

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

published property

Enabled

Specifies whether the element is enabled or disabled. By default, disabled elements are not exported or detected by the FMX.RS.SVG.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.

published property

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 FMX.RS.SVG.TSVGGraphicElement.)

published property

Font

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

protected property

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 FMX.RS.SVG.TSVGGraphicElement.)

published property

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 FMX.RS.SVG.TSVGGraphicElement.WritingMode .

published property

GlyphOrientationVertical

This property is applied only to text written in a vertical FMX.RS.SVG.TSVGGraphicElement.WritingMode

public property

Height

Height of the element in the current user coordinate system

Note
Note that this property is before any transformation (i.e., FMX.RS.SVG.TSVGGraphicElement.Matrix property) is applied

public property

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 FMX.RS.SVG.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.

Note
Note that this property is before any transformation (i.e., FMX.RS.SVG.TSVGGraphicElement.Matrix property) is applied

published property

Kerning

Specifies whether inter-glyph spacing should be adjusted based on behavior kerning tables that are included in the relevant font (i.e., enable auto-kerning) or instead disable auto-kerning and instead set inter-character spacing to a specific length (typically, zero).

note Note

Three properties affect the space between characters and words:

• ‘kerning’ indicates whether the user agent should adjust inter-glyph spacing based on kerning tables that are included in the relevant font (i.e., enable auto-kerning) or instead disable auto-kerning and instead set inter-character spacing to a specific length (typically, zero).

• ‘letter-spacing’ indicates an amount of space that is to be added between text characters supplemental to any spacing due to the ‘kerning’ property.

• ‘word-spacing’ indicates the spacing behavior between words.

Note that the final transformation of the element depends on its Parents' transformation matrices

published property

Opacity

Uniform opacity setting to be applied across an entire object, as a . Any values outside the range 0.0 (fully transparent) to 1.0 (fully opaque) will be clamped to this range. (Inherited from FMX.RS.SVG.TSVGGraphicElement.)

published property

OpacityPreferredUnit

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

public property

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).

(Inherited from FMX.RS.SVG.TSVGElement.)

published property

Overflow

Specifies whether the content of a block-level element is clipped when it overflows the element's box (which is acting as a containing block for the content) (Inherited from FMX.RS.SVG.TSVGGraphicElement.)

public property

Owner

Returns the Owner SVG document for the SVG element. (Inherited from FMX.RS.SVG.TSVGElement.)

public property

published property

PreferredStyles

Defines which style properties should be exported as a style (e.g., style=" fill:red; fill-opacity:1;" or as an attribute (e.g., fill="red").

Include style properties in this property to have the style property output as part of the style="" attribute.

published property

Note
Not all elements define a path shape

protected property

ShapeCacheChanged

Specifies whether the Shape has been changed and needs to be reinitializated by the GetShape method. Set this property to false to force initialization of the ShapeCache for the current SVG element. (Inherited from FMX.RS.SVG.TSVGGraphicElement.)

published property

published property

VectorEffect

Modifies the way an object is stroked. 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. (Inherited from FMX.RS.SVG.TSVGGraphicElement.)
