		1042
		1043	This extension also provides support for the old options/resources and

		1053	=item B<backgroundPixmap:> I<file[;oplist]>
		1054
		1055	Use the specified image file as the window's background and also
		1056	optionally specify a colon separated list of operations to modify it.
		1057	Note that you may need to quote the C<;> character when using the
		1058	command line option, as C<;> is usually a metacharacter in shells.
		1059	Supported operations are:
		1060
		1061	=over
		1062
		1063	=item B<WxH+X+Y>
		1064
		1065	sets scale and position. B<"W" / "H"> specify the horizontal/vertical
		1066	scale (percent), and B<"X" / "Y"> locate the image centre (percent). A
		1067	scale of 0 disables scaling.

		1081
		1082	=back
		1083
		1084	The default scale and position setting is C<100x100+50+50>.
		1085	Alternatively, a predefined set of templates can be used to achieve
		1086	the most common setups:
		1087
		1088	=over
		1089

		1091
		1092	the image is tiled with no scaling. Equivalent to 0x0+0+0:op=tile
		1093
		1094	=item B<style=aspect-stretched>
		1095
		1096	the image is scaled to fill the whole window maintaining the aspect
		1097	ratio and centered. Equivalent to 100x100+50+50:op=keep-aspect
		1098
		1099	=item B<style=stretched>
		1100
		1101	the image is scaled to fill the whole window. Equivalent to 100x100
		1102
		1103	=item B<style=centered>
		1104
		1105	the image is centered with no scaling. Equivalent to 0x0+50+50
		1106
		1107	=item B<style=root-tiled>
		1108
		1109	the image is tiled with no scaling and using 'root' positioning.
		1110	Equivalent to 0x0:op=tile:op=root-align
		1111
		1112	=back
		1113
		1114	If multiple templates are specified the last one wins. Note that a
		1115	template overrides all the scale, position and operations settings.
		1116
		1117	If used in conjunction with pseudo-transparency, the specified image
		1118	will be blended over the transparent background using alpha-blending.
		1119
		1120	=item B<-tr>\|B<+tr>
		1121
		1122	=item B<transparent:> I<boolean>

		1125
		1126	=item B<-tint> I<colour>
		1127
		1128	=item B<tintColor:> I<colour>
		1129
		1130	Tint the transparent background with the given colour. Note that a
		1131	black tint yields a completely black image while a white tint yields
		1132	the image unchanged.
		1133
		1134	=item B<-sh> I<number>
		1135
		1136	=item B<shading:> I<number>
		1137
		1138	Darken (0 .. 99) or lighten (101 .. 200) the transparent background.

		1140
		1141	=item B<-blr> I<HxV>
		1142
		1143	=item B<blurRadius:> I<HxV>
		1144
		1145	Apply gaussian blur with the specified radius to the transparent
		1146	background. If a single number is specified, the vertical and
		1147	horizontal radii are considered to be the same. Setting one of the
		1148	radii to 1 and the other to a large number creates interesting effects
		1149	on some backgrounds. The maximum radius value is 128. An horizontal or
		1150	vertical radius of 0 disables blurring.

		1154	=head2 OSC sequences
		1155
		1156	This extension will react to the following OSC sequences. Note that
		1157	this extension will not be autoloaded when these are used currently,
		1158	so to make urxvt recognize them, you have to enable the C<background>
		1159	extension. One way to achieve that is to use the C<--background-expr ''>
		1160	command line argument or by specifying an empty C<URxvt.background.expr:>>
