xcb\_image\_text\_8(3) XCB Requests xcb\_image\_text\_8(3)

# [NAME](#NAME)

xcb\_image\_text\_8 - Draws text

# [SYNOPSIS](#SYNOPSIS)

**#include <xcb/xproto.h>**

## [Request function](#Request_function)

xcb\_void\_cookie\_t **xcb\_image\_text\_8**(xcb\_connection\_t \**conn*, uint8\_t *string\_len*, xcb\_drawable\_t *drawable*, xcb\_gcontext\_t *gc*, int16\_t *x*, int16\_t *y*, const char \**string*);

# [REQUEST ARGUMENTS](#REQUEST_ARGUMENTS)

[*conn*](#conn)

The XCB connection to X11.

[*string\_len*](#string_len)

The length of the *string*. Note that this parameter limited by 255 due to using 8 bits!

[*drawable*](#drawable)

The drawable (Window or Pixmap) to draw text on.

[*gc*](#gc)

The graphics context to use.

The following graphics context components are used: plane-mask, foreground, background, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.

[*x*](#x)

The x coordinate of the first character, relative to the origin of *drawable*.

[*y*](#y)

The y coordinate of the first character, relative to the origin of *drawable*.

[*string*](#string)

The string to draw. Only the first 255 characters are relevant due to the data type of *string\_len*.

# [DESCRIPTION](#DESCRIPTION)

Fills the destination rectangle with the background pixel from *gc*, then paints the text with the foreground pixel from *gc*. The upper-left corner of the filled rectangle is at \[x, y - font-ascent]. The width is overall-width, the height is font-ascent + font-descent. The overall-width, font-ascent and font-descent are as returned by *xcb\_query\_text\_extents* (TODO).

Note that using X core fonts is deprecated (but still supported) in favor of client-side rendering using Xft.

# [RETURN VALUE](#RETURN_VALUE)

Returns an *xcb\_void\_cookie\_t*. Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with *xcb\_request\_check* instead, use *xcb\_image\_text\_8\_checked*. See [**xcb-requests(3)**](/man/os/libxcb/xcb-requests.3) for details.

# [ERRORS](#ERRORS)

[*xcb\_drawable\_error\_t*](#xcb_drawable_error_t)

The specified *drawable* (Window or Pixmap) does not exist.

[*xcb\_g\_context\_error\_t*](#xcb_g_context_error_t)

The specified graphics context does not exist.

[*xcb\_match\_error\_t*](#xcb_match_error_t)

TODO: reasons?
