LSL: string osSetPenColour( string drawList, string colour )
LSL: string osMovePen( string drawList, string colour )
Sets the pen's drawing color to either the specified named .NET color or to a 32-bit color value (formatted as eight hexadecimal digits in the format aarrggbb, representing the eight-bit alpha, red, green and blue channels).
For full opacity, use an alpha value of ff (e.g. ffff0000 for red); for varying degrees of transparency, reduce the alpha value (e.g. 800000ff for half-transparent blue).
The color names and hexadecimal color representations are not case-sensitive.
Example:
// Example of osSetPenColour string hexDigits = "0123456789abcdef"; list colorNames = [ "AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenrod", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "DarkOrange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "Goldenrod", "Grey", "Green", "GreenYellow", "Honeydew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenrodYellow", "LightGreen", "LightGrey", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquamarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenrod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "Seashell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen" ]; default { state_entry() { string CommandList = ""; // Storage for our drawing commands integer i; CommandList = osSetPenSize( CommandList, 1 ); // Set the pen width to 1 pixel for (i = 0; i < 140; ++i) // draw each named color as a single horizontal line { // Set the pen to the next color name in our list CommandList = osSetPenColour( CommandList, llList2String( colorNames, i )); // Now draw a line in that color CommandList = osDrawLine( CommandList, 0, i, 255, i ); } // Now let's fill up the remainder with lines of random colors, leaving a gap of 20 lines. for (i = 161; i < 256; ++i) { string thisColor = "ff"; // give it an opaque alpha integer j; for (j = 0; j < 6; ++j) // then choose six random hex digits for the color { integer k = (integer) llFrand( 16.0 ); thisColor += llGetSubString( hexDigits, k, k ); } CommandList = osSetPenColour( CommandList, thisColor ); CommandList = osDrawLine( CommandList, 0, i, 255, i ); } // Now generate the texture and apply it to the prim osSetDynamicTextureData( "", "vector", CommandList, "width:256,height:256", 0 ); } }
