TSVGDocument Class

Create(TSVGDocument)

Initializes a new instance of the TSVGDocument class. (Overrides FMX.RS.SVG.TSVGCustomViewBox.Create(TSVGDocument).)

Destroy

Represents the destructor of the TSVGDocument class. (Overrides FMX.RS.SVG.TSVGCustomViewBox.Destroy.)

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.

AllItems

Contains all SVG elements (visual and non-visual) parsed from a SVG. The TSVGElement.ID property is the hash for each element.

AllItemsModified

Represents property AllItemsModified.

AspectRatio

Represents property AspectRatio.

Attributes

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

CalcBR

Represents property CalcBR. (Inherited from FMX.RS.SVG.TSVGCustomGroup.)

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.)

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.)

ClipRect

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

ClipRule

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

VCL Only

DefaultColorRendering

VCL Only

DefaultTextRendering

Default Text rendering type, which provides a hint to the SVG library about what tradeoffs to make as it renders text

VCL Only

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.)

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.

DPI

Dots per inch used in calculating the unit factors for conversion of string lengths into actual values. The DPI should be set before loading SVG.

For example, if the input string contains '1cm', the DPI helps the SVG library figure out how large a centimeter is.

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.)

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.

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.)

Font

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

FormatStr

Defines the format of floating point numbers output when exporting the SVG XML. This property can dramatically affect the size of SVG files. Specify higher precision format strings (e.g., '0.##############') to ensure numbers are exact as possible at the cost of file size. Specify lower precision format strings (e.g., '0.###') for smaller files with the risk that some precision may be lost.

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 .

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 FMX.RS.SVG.TSVGGraphicElement.WritingMode

OpacityPreferredUnit

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

• Count the number of type selectors and pseudo-elements in the selector (= c)

• Ignore the universal selector

• Selectors inside the negation pseudo-class are counted like any other, but the negation itself does not count as a pseudo-class.

OnAddElement

Occurs when an element has been added to the list of child Items of an element

Note that this event does not get called if the update count is greater than 0 because of a BeginUpdate method call. It will not be called when EndUpdate is called either. In this case, monitor the OnChange event. If the sender is nil, the structure may have been changed.

OnAddStyle

Occurs when a style is added to the document

OnDisableAppearance

Occurs just before a disabled element is about to be drawn to the canvas. Use this event to modify the Canvas, Matrix, or aRect to provide a special appearance for disabled elements.

Set the DoDefault parameter to false to prevent the default disabled appearance (making the element grayscale) from being performed

OnDrawing

Occurs just before drawing the current element and its children. The event fires after the canvas brush, pen, font, clipping, etc are set up but before the actual drawing.

OnDrawn

Occurs just after a SVG element is drawn. The event fires after drawing the current element and its children but before the canvas is returned to its initial state.

OnRemoveElement

Occurs when an element has been removed from the list of child Items of an element.

Note that this event does not get called if the update count is greater than 0 because of a BeginUpdate method call. It will not be called when EndUpdate is called either. In this case, monitor the OnChange event. If the sender is nil, the structure may have been changed.

OnRemoveStyle

Occurs when a style is extracted or removed from the document

OnSavedElement

Occurs just after a SVG element and its children are saved to an IXMLNode.

OnSavingElement

Occurs just before an SVG element and its children are saved to an IXMLNode. Set DoSave to False to prevent the SVG element from being saved
