Zoom::Zoom (  ) 


Member Function Documentation

bool Zoom::set_param ( const String &  param,
const synfig::ValueBase value 
) [virtual]

Sets the parameter described by param to value.

Parameters:
param The name of the parameter to set
value What the parameter is to be set to.
Returns:
true on success, false upon rejection or failure. If it returns false, then the Layer is assumed to remain unchanged.
See also:
get_param()
Todo:
param should be of the type const String &param

Reimplemented from synfig::Layer.

References IMPORT.

ValueBase Zoom::get_param ( const String &  param  )  const [virtual]

Get the value of the specified parameter.

Returns:
The requested parameter value, or (upon failure) a NIL ValueBase.
See also:
set_param()
Todo:
param should be of the type const String &

Reimplemented from synfig::Layer.

Color Zoom::get_color ( Context  context,
const Point pos 
) const [virtual]

Gets the color of the Canvas at pos.

Parameters:
context Context iterator referring to next Layer.
pos Point which indicates where the Color should come from
See also:
Handle::get_color()

Reimplemented from synfig::Layer.

References synfig::Context::get_color().

bool Zoom::accelerated_render ( Context  context,
Surface surface,
int  quality,
const RendDesc renddesc,
ProgressCallback cb 
) const [virtual]

Renders the Canvas to the given Surface in an accelerated manner.

Parameters:
context Context iterator referring to next Layer.
surface Pointer to Surface to render to.
quality The requested quality-level to render at.
renddesc The associated RendDesc.
cb Pointer to callback object. May be NULL if there is no callback.
Returns:
true on success, false on failure
See also:
Handle::accelerated_render()

Reimplemented from synfig::Layer.

References synfig::Context::accelerated_render(), synfig::RendDesc::clear_flags(), synfig::RendDesc::get_br(), synfig::RendDesc::get_tl(), synfig::RendDesc::set_br(), and synfig::RendDesc::set_tl().

synfig::Layer::Handle Zoom::hit_check ( synfig::Context  context,
const synfig::Point point 
) const [virtual]

Checks to see if a part of the layer is directly under point.

Parameters:
context Context iterator referring to next Layer.
point The point to check
Returns:
The handle of the layer under point. If there is not a layer under point, then returns an empty handle.

Reimplemented from synfig::Layer.

References synfig::Context::hit_check().

Layer::Vocab Zoom::get_param_vocab ( void   )  const [virtual]

Gets the parameter vocabulary.

Reimplemented from synfig::Layer.

References _, and synfig::Layer::set_description().

synfig::Rect Zoom::get_full_bounding_rect ( synfig::Context  context  )  const [virtual]

etl::handle< Transform > Zoom::get_transform (  )  const [virtual]

Todo:
This needs to be documented further.

Reimplemented from synfig::Layer.
