LSL: vector osGetDrawStringSize( string contentType, string text, string fontName, integer fontSize )
C#: LSL_Vector osGetDrawStringSize( string contentType, string text, string fontName, int fontSize )
Returns a vector containing the horizontal and vertical dimensions in pixels of the specified text, if drawn in the specified font and at the specified point size. The horizontal extent is returned in the .x component of the vector, and the vertical extent is returned in .y. The .z component is not used.
The contentType parameter should be "vector".
If the osSetFontSize() function has not been used, and neither the FontName nor FontProp commands have been added to the draw list, specify "Arial" as the font name, and 14 as the font size.
Example:
// Example of osGetDrawStringSize default { state_entry() { string CommandList = ""; // Storage for our drawing commands string TextToDraw = "Hello, World!"; // text to draw vector Extents = osGetDrawStringSize( "vector", TextToDraw, "Arial", 14 ); integer xpos = 128 - ((integer) Extents.x >> 1); // Center the text horizontally integer ypos = 127 - ((integer) Extents.y >> 1); // and vertically CommandList = osMovePen( CommandList, xpos, ypos ); // Position the text CommandList = osDrawText( CommandList, TextToDraw ); // Place the text // Now draw the text osSetDynamicTextureData( "", "vector", CommandList, "width:256,height:256", 0 ); } }
