Detailed Description

This class provides some useful functions to draw with OpenGL.

Define Documentation

#define cairo_dock_create_texture_from_image ( cImagePath )

Load an image on the dock into an OpenGL texture. The texture will have the same size as the image.

Parameters:

cImagePath path to an image.

Returns:: the newly allocated texture, to be destroyed with _cairo_dock_delete_texture.

#define _cairo_dock_delete_texture ( iTexture )

Delete an OpenGL texture from the Graphic Card.

Parameters:

iTexture variable containing the ID of a texture.

#define _cairo_dock_enable_texture ( ... )

Enable texture drawing.

#define _cairo_dock_disable_texture ( ... )

Disable texture drawing.

#define _cairo_dock_set_alpha ( fAlpha )

Set the alpha channel to a current value, other channels are set to 1.

Parameters:

fAlpha alpha

#define _cairo_dock_set_blend_source ( ... )

Set the color blending to overwrite.

#define _cairo_dock_set_blend_alpha ( ... )

Set the color blending to mix, for premultiplied texture.

#define _cairo_dock_set_blend_over ( ... )

Set the color blending to mix.

#define _cairo_dock_set_blend_pbuffer ( ... )

Set the color blending to mix on a pbuffer.

#define _cairo_dock_apply_texture_at_size	(	iTexture,
		w,
		h
	)

Draw a texture centered on the current point, at a given size.

Parameters:

iTexture	the texture
w	width
h	height

#define _cairo_dock_apply_texture ( iTexture )

Apply a texture centered on the current point and at the given scale.

Parameters:

iTexture the texture

#define _cairo_dock_apply_texture_at_size_with_alpha	(	iTexture,
		w,
		h,
		fAlpha
	)

Draw a texture centered on the current point, at a given size, and with a given transparency.

Parameters:

iTexture	the texture
w	width
h	height
fAlpha	the transparency, between 0 and 1.

Function Documentation

void cairo_dock_render_one_icon_opengl	(	Icon *	icon,
		CairoDock *	pDock,
		double	fDockMagnitude,
		gboolean	bUseText
	)

Draw an icon, according to its current parameters : position, transparency, reflect, rotation, stretching. Also draws its indicators, label, and quick-info. It generates a CAIRO_DOCK_RENDER_ICON notification.

Parameters:

icon	the icon to draw.
pDock	the dock containing the icon.
fDockMagnitude	current magnitude of the dock.
bUseText	TRUE to draw the labels.

GLuint cairo_dock_create_texture_from_surface ( cairo_surface_t * pImageSurface )

Load a cairo surface into an OpenGL texture. The surface can be destroyed after that if you don't need it. The texture will have the same size as the surface.

Parameters:

pImageSurface the surface, created with one of the 'cairo_dock_create_surface_xxx' functions.

Returns:: the newly allocated texture, to be destroyed with _cairo_dock_delete_texture.

GLuint cairo_dock_load_texture_from_raw_data	(	const guchar *	pTextureRaw,
		int	iWidth,
		int	iHeight
	)

Load a pixels buffer representing an image into an OpenGL texture.

Parameters:

pTextureRaw	a buffer of pixels.
iWidth	width of the image.
iHeight	height of the image.

Returns:: the newly allocated texture, to be destroyed with _cairo_dock_delete_texture.

GLuint cairo_dock_create_texture_from_image_full	(	const gchar *	cImagePath,
		double *	fImageWidth,
		double *	fImageHeight
	)

Load an image on the dock into an OpenGL texture. The texture will have the same size as the image. The size is given as an output, if you need it for some reason.

Parameters:

cImagePath	path to an image.
fImageWidth	pointer that will be filled with the width of the image.
fImageHeight	pointer that will be filled with the height of the image.

Returns:: the newly allocated texture, to be destroyed with _cairo_dock_delete_texture.

void cairo_dock_update_icon_texture ( Icon * pIcon )

Update the icon's texture with its current cairo surface. This allows you to draw an icon with libcairo, and just copy the result to the OpenGL texture to be able to draw the icon in OpenGL too.

Parameters:

pIcon the icon.

void cairo_dock_update_label_texture ( Icon * pIcon )

Update the icon's label texture with its current label surface.

Parameters:

pIcon the icon.

void cairo_dock_update_quick_info_texture ( Icon * pIcon )

Update the icon's quick-info texture with its current quick-info surface.

Parameters:

pIcon the icon.
