GVnc.Framebuffer
Description: Reference for GVnc.Framebuffer

### Interface

# GVncFramebuffer

#### Description

    interface GVnc.Framebuffer : GObject.Object

No description available.

#### Prerequisite

In order to implement Framebuffer, your type must inherit from `GObject`.

#### Implementations

- VncBaseFramebuffer

#### Instance methods

###### vnc_framebuffer_blt

No description available.

###### vnc_framebuffer_copyrect

Copies data from the range (`srcx`, `srcy`) to (`srcx`+`width`, `srcy`+`height`) over to the range starting at (`dstx`, `dsty`).

###### vnc_framebuffer_fill

Fill all the pixels in the range (`x`, `y`) to (`x` + `width`, `y` + `height`) to the value in `src`. The number of bytes in `src` is determined by the remote pixel format.

###### vnc_framebuffer_get_buffer

Get a pointer to the framebuffer contents.

###### vnc_framebuffer_get_height

Query the height of the remote framebuffer.

###### vnc_framebuffer_get_local_format

Get the pixel format used to store the framebuffer locally.

###### vnc_framebuffer_get_remote_format

No description available.

###### vnc_framebuffer_get_rowstride

Get the number of bytes per line of the framebuffer.

###### vnc_framebuffer_get_width

Query the width of the remote framebuffer.

###### vnc_framebuffer_perfect_format_match

Determine if the local and remote pixel formats match.

###### vnc_framebuffer_rgb24_blt

Fill all the pixels in the range (`x`, `y`) to (`x` + `width`, `y` + `height`) to the value in `src`. The number of bytes in `src` is always 3 as it must be in plain RGB24 format.

###### vnc_framebuffer_set_color_map

Set the color map to use for the framebuffer.

###### vnc_framebuffer_set_pixel_at

Sets a pixel in the framebuffer at (`x`, `y`) to the value in `src`. The number of bytes in `src` is determined by the remote pixel format.
