Overview

Each character image, as defined by the font in the GC, is treated as an additional mask for a fill operation on the drawable. The drawable is modified only where the font character has a bit set to 1. For fonts defined with 2-byte matrix indexing and used with XDrawString16, each byte is used as a byte2 with a byte1 of zero.

Both functions use these GC components: function, plane-mask, fill-style, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

XDrawString and XDrawString16 can generate BadDrawable, BadGC, and BadMatch errors.

Diagnostics

BadDrawable

BadGC

A value for a GContext argument does not name a defined GContext.

BadMatch

An InputOnly window is used as a Drawable.

BadMatch

Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
