member of the XColor structures.
If the colormap is an installed map for its screen, the
changes are visible immediately.
XStoreColors changes the specified pixels
if they are allocated writable in the colormap
by any client, even if one or more pixels generates an error.
If a specified pixel is not a valid index into the colormap,
a ``BadValue'' error results.
If a specified pixel either is unallocated or is allocated read-only,
a ``BadAccess'' error results.
If more than one pixel is in error,
the one that gets reported is arbitrary.
XStoreColors can generate ``BadAccess'', ``BadColor'', and ``BadValue'' errors.
The XStoreColor function changes the colormap
entry of the pixel value specified in the pixel member of the
XColor structure.
You specified this value in the pixel member of the
XColor structure.
This pixel value must be a read/write cell and a valid index into the colormap.
If a specified pixel is not a valid index into the colormap,
a ``BadValue'' error results.
XStoreColor
also changes the red, green, and/or blue color components.
You specify which color components are to be changed by setting
DoRed, DoGreen, and/or DoBlue
in the flags
member of the XColor structure.
If the colormap is an installed map for its screen,
the changes are visible immediately.
XStoreColor can generate ``BadAccess'', ``BadColor'', and ``BadValue'' errors.
The XStoreNamedColor function looks up the named color with respect to the screen associated with the colormap and stores the result in the specified colormap. The pixel argument determines the entry in the colormap. The flags argument determines which of the red, green, and blue components are set. You can set this member to the bitwise inclusive OR of the bits DoRed, DoGreen, and DoBlue. If the color name is not in the Host Portable Character, Encoding the result is implementation-dependent. Use of uppercase or lowercase does not matter. If the specified pixel is not a valid index into the colormap, a ``BadValue'' error results. If the specified pixel either is unallocated or is allocated read-only, a ``BadAccess'' error results.
XStoreNamedColor can generate ``BadAccess'', ``BadColor'', ``BadName'', and ``BadValue'' errors.
