Detailed Description

This class is the OpenVG specific representation of a Gnash Cached Bitmap.

Member Enumeration Documentation

enum gnash::renderer::openvg::OpenVGBitmap::bitmap_wrap_mode

Set line and fill styles for mesh & line_strip rendering.

Enumerator:

WRAP_REPEAT
WRAP_FILL
WRAP_PAD
WRAP_REFLECT

Constructor & Destructor Documentation

gnash::renderer::openvg::OpenVGBitmap::OpenVGBitmap ( VGPaint paint )

Parameters:

vgpaint the VG paint context

gnash::renderer::openvg::OpenVGBitmap::OpenVGBitmap	(	CachedBitmap *	bitmap,
		VGPaint	vgpaint
	)

Construct a new bitmap

Parameters:

bitmap	A CachedBitmap
vgpaint	the VG paint context

gnash::renderer::openvg::OpenVGBitmap::OpenVGBitmap	(	image::GnashImage *	image,
		VGPaint	vgpaint
	)

Construct a new bitmap

Parameters:

A	pointer to a GnashImage
vgpaint	the VG paint context

Note:: This is usually only called by createCachedBitmap() when a bitmap is loaded from a swf file. As the renderer isn't initialized yet, only the GnashImage is cached.

		bitmap_wrap_mode	mode,
		CachedBitmap *	bitmap,
		VGPaint	paint
	)

Create and fill pattern image

Parameters:

matrix	The transformation matrix
mode	The mode used to pain the image
paint	The VG paint context

Returns:: A pointer to the new Bitmap

OpenVGBitmap * gnash::renderer::openvg::OpenVGBitmap::createLinearBitmap	(	float	x0,
		float	y0,
		float	x1,
		float	y1,
		const SWFCxForm &	cxform,
		const GradientFill::GradientRecords &	records,
		const VGPaint	paint
	)

Create a linear gradient and paint it to the context

Parameters:

x0	The X coordinate of the origin point
y0	The Y coordinate of the origin point
x1	The X coordinate of the opposite corner point
y1	The Y coordinate of the opposite corner point
incolor	The base color of the gradient
paint	The VG paint context

Returns:: A pointer to the new Bitmap

Note:: A Linear Gradient Bitmap uses two points, x0,y0 and x1,y1 in the paint coordinate system. The gradient starts at x0,y0 and goes to x1,y1. If x1 and y1 are outside the boundaries of the shape, then the gradient gets clipped at the boundary instead of x1,y1.

OpenVGBitmap * gnash::renderer::openvg::OpenVGBitmap::createRadialBitmap	(	float	cx,
		float	cy,
		float	fx,
		float	fy,
		float	radial,
		const SWFCxForm &	cx,
		const GradientFill::GradientRecords &	records,
		VGPaint	paint
	)

Create a radial gradient and paint it to the context

Parameters:

x0	The X coordinate of the origin point
y0	The Y coordinate of the origin point
x1	The X coordinate of the opposite corner point
y1	The Y coordinate of the opposite corner point
incolor	The base color of the gradient
paint	The VG paint context

Returns:: A pointer to the new Bitmap

Note:: OpenVG supports creating linear and gradient fills in hardware, so we want to use that instead of the existing way of calculating the gradient in software.

void gnash::renderer::openvg::OpenVGBitmap::dispose ( ) [inline, virtual]

Free the memory associated with this CachedBitmap.

This allows ActionScript a little bit of control over memory.

Implements gnash::CachedBitmap.

bool gnash::renderer::openvg::OpenVGBitmap::disposed ( ) const [inline, virtual]

Whether the CachedBitmap has been disposed.

A disposed CachedBitmap has no data and should not be rendered.

Implements gnash::CachedBitmap.
