The driver + allocates colors as they are requested - if a color cannot be allocated, the + closest color is used in the palette. For such, the driver sees all available + colors, in the current application and others. If one of the applications is + terminated, a color in the palette may become invalid and will only be updated + by the driver when it is requested again. For this reason, a call to <strong> + cdForeground </strong>or <strong>cdBackground</strong> or <strong>cdPalette</strong> + is recommended before drawing.<br> + When CD_FORCE is used, the driver forces color allocation in the X server. + This may imply changing colors in other applications when a cursor moves in + and out of the canvas. However, if the number of requested colors is smaller + than the maximum number of possible colors in the palette, then the first + colors in the default system palette will be preserved, minimizing this + problem.<br> + When CD_POLITE is used, all colors allocated by the driver are liberated, and + the requested colors are allocated. This is useful for the application to + prioritize the colors that will be allocated, causing other colors to be + mapped to their closest colors.<br> + Note that canvases in the same application interfere with one another, but + when a canvas is terminated it liberates all allocated colors.</li> +</ul> +<h4>Client Images</h4> +<ul> + <li> + <a href="../func/client.html#cdGetImageRGB"> + <font face="Courier"><strong>GetImageRGB</strong></font></a>: can be very + slow due to the heavy conversions performed to translate data in system format + into RGB vectors. </li> +</ul> +<h4>Exclusive Attributes</h4> +<ul> + <li>"<b><font face="Courier">GC</font></b>": returns the X11 graphics + context (get only).
