.TH CG-RAINBOW 1 CG-TOOLS .SH NAME cg-rainbow - Adds a rainbow cycle effect to the monitors .SH SYNOPSIS .B cg-rainbow .RB [ \-M .IR method ] .RB [ \-S .IR site ] .RB [ \-c .IR crtc "]... ["\fB\-R\fP .IR rule ] .RB [ \-p .IR priority ] .RB [ \-l .IR luminosity ] .RB [ \-s .IR rainbowhz ] .SH DESCRIPTION .B cg-rainbow cycles between a the rainbow's colors and use the colours as the monitors' white colour. .P .B cg-rainbow is a rewrite of .BR xrainbow (1) and .BR grainbow (1). .SH OPTIONS .TP .BR \-l " "\fIluminosity\fP Select the luminosity of the rainbow. A value of 0 means the rainbow is completely black, and a value of 1 means the the rainbow is fully saturated, but not oversaturated. The default luminosity is one third. .TP .BR \-s " "\fIrainbowhz\fP Select the number of of rainbow-cycles per second. The default frequency is one third. .TP .BR \-c " "\fIcrtc\fP Apply the filter to the CRTC with the monitor whose EDID is .IR crtc . By default, the filter is applied to all monitors. If .I crtc is .RB ' ? ', all available CRTC's are listed. .TP .BR \-M " "\fImethod\fP Adjustment method name or number. Recognised names include: .TS tab(:); l l. \fBdummy\fP:Dummy method \fBrandr\fP:X RAndR \fBvidmode\fP:X VidMode \fBdrm\fP:Linux DRM \fBgdi\fP:Windows GDI \fBquartz\fP:Quartz Core Graphics .TE The adjustment methods are supported via .BR libgamma (7). Only methods that were enabled when .B libgamma was compiled will be supported. If .I method is .RB ' ? ', all available adjustment methods are printed. .TP .BR \-p " "\fIpriority\fP Set the priority of the filter. Filters with higher priority are applied before filters with lower priority. The value must be a signed 64-bit integer (between -9223372036854775807 and 9223372036854775808). .BR cg-rainbow 's default priority is 1152921504606846976. If .I priority is .RB ' ? ', the utility's default priority is printed. .TP .BR \-R " "\fIrule\fP Set the rule of of the filter to .IR rule . This is the last part of the filter's identifier (class). The default rule is .BR standard . If .I rule is .RB ' ? ' the utility's default rule is printed. If .I rule is .RB ' ?? ' the utility's default class is printed. .TP .BR \-S " "\fIsite\fP Select the site to which to connect. For example .RB ' :0 ', for local display 0 when using .BR X . .SH "SEE ALSO" .BR cg-tools (7) .SH BUGS Please report bugs to https://github.com/maandree/cg-tools/issues or to maandree@kth.se
