.WIDGET CNV RGB TO CLR This subroutine converts a decimal color code to alpha/hex. Usage:
Description: This subroutine converts a decimal color code to alpha/hex. This is useful for converting colors in the --- WIDGET file (255, 255, 0, 0) format to web or hex color codes (ie, #FFFF0000). Both parameters are required, and the subroutine will cancel if they are not received. <clr_alpha> is the hex color code returned (Required). This must be PASSed with Share "Y" to return the value. This will be in the format '#RRGGBBTT' or '#RRGGBB' where RR is the hex value for Red, GG is the hex value for Green, BB is the hex value for Blue and TT is the transparency. Other values for TT are 2-255 where 2 is nearaly fully transparent and 255 is fully opaque. The transparency is optional, and will be blank if zero or one in <clr_binary>. <clr_binary> is the color value to be converted (Required). This should be a Group Header field, where the group consists of 4 numeric fields, 9(3), binary format. This corresponds to the layout of the various color fields in the --- WIDGET file, so you may use them directly. The fields are:
