Static Public Member Functions
static drain::image::TreeSVG &	getStyle (RackContext &ctx)
	Some SVG style classes. Identifiers for IMAGE and RECT elements over which TEXT elements will be aligned.

	returns timeformat
static drain::image::TreeSVG &	getMainGroup (RackContext &ctx)
	Top-level GROUP used by Rack. All the graphic elements will be created inside this element.

Detailed Description

SVG support for creating aligned image panels.

Member Function Documentation

addImage() [1/3]

void addImage ( RackContext &  ctx, const drain::Frame2D< drain::image::svg::coord_t > &  frame, const drain::FilePath &  filepath, const std::string &  styleClass = ""  )

static

Add external image from a file path.

Add pixel image (PNG)

Parameters

styleClass

- optional style class, possibly FLOAT

addImage() [2/3]

void addImage ( RackContext &  ctx, const drain::image::Image &  src, const drain::FilePath &  filepath  )

static

Add pixel image (PNG).

Idea: keep this minimal, add components only upon (eventual) saving of the SVG file.

addImage() [3/3]

void addImage ( RackContext &  ctx, const drain::image::TreeSVG &  svg, const drain::FilePath &  filepath  )

static

Currently, uses file link (does not embed)

Add SVG image.

addImageBorder()

drain::image::TreeSVG & addImageBorder ( drain::image::TreeSVG &  imagePanel )

static

Add.

Parameters

imagePanel

addTitleBox()

drain::image::TreeSVG & addTitleBox ( const ConfSVG &  conf, drain::image::TreeSVG &  object, RackSVG::ElemClass  elemClass  )

static

Create a title from background rectangle and TEXT elements (MAINTITLE, LOCATION, TIME, GENERAL)

Returns

TEXT element located at child(GENERAL)

appendTitleElements()

drain::image::TreeSVG & appendTitleElements ( const ConfSVG &  conf, drain::image::TreeSVG &  group, const std::string &  anchor, RackSVG::ElemClass  elemClass  )

static

Add title elements in given group, to "reserve slots" for actual text content to be added later.

TODO const double fontSize = // getStyleValue(root, RackSVG::TITLE, "font-size", 12.5); root[drain::image::svg::STYLE][elemClass]->get("font-size", 12.5);

getStyle()

drain::image::TreeSVG & getStyle ( RackContext &  ctx )

static

Some SVG style classes. Identifiers for IMAGE and RECT elements over which TEXT elements will be aligned.

Group identifiers for elements which be automatically aligned (stacked horizontally or vertically)

Initialize styles, if undone.
