.TH TYPES 9.SH NAMEtypes \- Standard types required by widget options..SH DESCRIPTIONThis manual entry describes the the standard typesthat can be given as arguments to Inferno Tk widgetoptions. When an option is documented, the typeof argument that it accepts is either documentedthere, or the name of the argument refers to one of thenames documented below..TP.I anchorPosOne of the values \f5n\fR, \f5ne\fR, \f5e\fR, \f5se\fR,\f5s\fR, \f5sw\fR, \f5w\fR, \f5nw\fR, or \f5center\fR.See.B -anchorin.IR options (9)..TP.I booleanA true or false value, one of the following:\f50\fP, \f5no\fP, \f5off\fP, \f5false\fP (false),\f51\fP, \f5yes\fP, \f5on\fP, \f5true\fP (true)..TP.I bitmapIdentifies an image which can be drawn, or used as a maskthrough which something else is drawn. If.I bitmapbegins with a.RB ` @ ',the remaining characters must be the path name ofan Inferno image file. If.I bitmapbegins with the character.RB ` < ',the remaining characters must be a decimal integergiving the file descriptor number of an open file (see.IR sys-open (2))from which the bitmap can be loaded. Otherwise,.I bitmapshould be the name of a bitmap file in the directory.BR /icons/tk ..TP.I colorA.I colorparameter can be a colour name or an RGB (red, green and blueluminance) value. The colour names recognized are:.EX    aqua     yellow   red      teal     white    fuchsia  black    blue     darkblue transparent    maroon   gray     green    lime    purple   navy     olive    orange.EEFor RGB values, either.BI # rgbor.BI # rrggbbcan be used, where.IR r ,.IR rr ,etc. are hexadecimal values for the corresponding colourcomponents.The notation.BI #rrggbbaacan be used to describe a colour with alpha (transparency) component.IR aa ;the.IR rr ,.IR gg ,and.IR bbvalues should be pre-multiplied appropriately. This is thecanonical form for colour values. Alternatively, transparencycan be applied to any other colour using a suffix.BI * alphawhere.I alphais either.BI #aa(two hex digits representing an alpha value between 0 and 255)or.I f(a decimal fixed point number between 0 and 1).For example,.B red*0.5gives half transparent red;.B #007f007f*#7fgives 0.75 transparent green (canonically.B #003f003f)..TP.I dist.I Distspecifies a distance on the screen, in the following form:an optional minus sign.RB ( - ),then one or more decimal digits (with possibleembedded decimal point), then an optional unitsspecifier. The unit specifiers are the following:.RS.TP.B ccentimetres.TP.B mmillimetres.TP.B iinches.TP.B ppoints (1/72th inch).TP.B hheight of widget's font (only applicable if the widgethas an associated font, and if the font has previously been set)..TP.B wwidth of the zero.RB ( 0 )character in widget's font. (see above)..TPMeasurements are converted into pixels assuming 100 dotsper inch on an average CRT display..RE.TP.I fontA.I fontparameter gives the full path name of an Inferno font file;for example,.BR /fonts/pelm/unicode.9.font ..TP.I fracA numeric, possibly fractional, value..TP.I reliefOne of \f5raised\fR, \f5sunken\fR, \f5flat\fR, \f5ridge\fR,or \f5groove\fR.
