dscBeginPageSetup
|
This function indicates that subsequent calls to
dscComment() should direct
comments to the PageSetup section of the PostScript output.

dscBeginSetup

This function indicates that subsequent calls to

dscComment
|
See
http://cairographics.org/manual/cairo-PostScript-Surfaces.html#cairo-ps-surface-dsc-comment
|
getEPS
|
Check whether the PostScript surface will output Encapsulated
PostScript.
|
restrictToLevel
|
Restricts the generated PostSript file to level.
See getPSLevels() for a list of available
level values that can be used here.
|
setEPS
|
If eps is true, the PostScript surface will output
Encapsulated PostScript.
|
setSize
|
hanges the size of a PostScript surface for the current
(and subsequent) pages.
|
copyPage
|
Emits the current page for backends that support multiple pages,
but doesn't clear it, so that the contents of the current page
will be retained for the next page. Use Surface.showPage()
if you want to get an empty page after the emission.
|
createForRectangle
|
Create a new surface that is a rectangle within the target surface.
All operations drawn to this surface are then clipped and translated
onto the target surface. Nothing drawn via this sub-surface
outside of its bounds is drawn onto the target surface,
making this a useful method for passing constrained child
surfaces to library routines that draw directly onto the parent
surface, i.e. with no further backend allocations, double
buffering or copies.
|
createFromNative
|
The createFromNative method for the Surface classes.
See https://github.com/jpf91/cairoD/wiki/Memory-Management#createFromNative
for more information.
|
createSimilar
|
Create a new surface that is as compatible as possible with
an existing surface. For example the new surface will have the
same fallback resolution and font options as other. Generally,
the new surface will also use the same backend as other, unless
that is not possible for some reason. The type of the returned
surface may be examined with Surface.getType().
|
finish
|
This function finishes the surface and drops all references
to external resources. For example, for the Xlib backend it
means that cairo will no longer access the drawable, which
can be freed. After calling Surface.finish() the only
valid operations on a surface are getting and setting user,
referencing and destroying, and flushing and finishing it.
|
flush
|
Do any pending drawing for the surface and also restore any temporary
modifications cairo has made to the surface's state. This function
must be called before switching from drawing on the surface
with cairo to drawing on it directly with native APIs. If the
surface doesn't support direct access, then this function does
nothing.
|
getContent
|
This function returns the content type of surface which indicates
whether the surface contains color and/or alpha information.
See Content.
|
getDevice
|
This function returns the device for a surface. See Device.
|
getDeviceOffset
|
This function returns the previous device offset set
by Surface.setDeviceOffset().
|
getFallbackResolution
|
This function returns the previous fallback resolution set
by setFallbackResolution(), or default
fallback resolution if never set.
|
getFontOptions
|
Retrieves the default font rendering options for the surface.
This allows display surfaces to report the correct subpixel
order for rendering on them, print surfaces to disable hinting
of metrics and so forth. The result can then be used with
ScaledFont().
|
getMimeData
|
Return mime data previously attached to surface using the
specified mime type. If no data has been attached with the given
mime type, data is set null.
|
getType
|
This function returns the C type of a Surface. See SurfaceType
for available types.
|
hasShowTextGlyphs
|
Returns whether the surface supports sophisticated showTextGlyphs()
operations. That is, whether it actually uses the provided text
and cluster data to a showTextGlyphs() call.
|
markDirty
|
Tells cairo that drawing has been done to surface using means
other than cairo, and that cairo should reread any cached areas.
Note that you must call Surface.flush() before doing such drawing.
|
markDirtyRectangle
|
Like Surface.markDirty(), but drawing has been done only
to the specified rectangle, so that cairo can retain cached
contents for other parts of the surface.
|
setDeviceOffset
|
Sets an offset that is added to the device coordinates determined
by the CTM when drawing to surface. One use case for this function
is when we want to create a Surface that redirects drawing
for a portion of an onscreen surface to an offscreen surface
in a way that is completely invisible to the user of the cairo API.
Setting a transformation via Context.translate() isn't sufficient
to do this, since functions like Context.deviceToUser() will
expose the hidden offset.
|
setFallbackResolution
|
Set the horizontal and vertical resolution for image fallbacks.
|
setMimeData
|
Attach an image in the format mime_type to surface. To remove
the data from a surface, call this function with same mime
type and NULL for data.
|
showPage
|
Emits and clears the current page for backends that support
multiple pages. Use Surface.copyPage() if you don't
want to clear the page.
|
checkError
|
Method for use in subclasses.
Calls cairo_surface_status(nativePointer) and throws
an exception if the status isn't CAIRO_STATUS_SUCCESS
