LSL: '''[[string]] osSetFontSize( [[string]] drawList, [[integer]] fontSize )'''<br />
C#: '''[[string]] osSetFontSize( [[string]] drawList, [[int]] fontSize )'''

Appends a [[Drawing_commands#FontSize|FontSize]] drawing command to the string provided in '''drawList''' and returns the result.

[http://www.online-casino-gaming.org/ casino online]

Sets the size of the font used by subsequent '''[[OsDrawText | osDrawTextText]]'''() calls. The '''fontSize''' parameter represents the font height in points.

Please note that the font height is given in ''points'', not in ''pixels''. The resulting size of the font in pixels may vary depending on the system settings, specifically the display system's "dots per inch" metric. A system set to 96dpi will produce differently sized text than a system set to 120dpi. If precise text size is required, consider using the [[osGetDrawStringSize]]() function to help calculate the proper fontSize value to use.

If a negative '''fontSize''' parameter is specified, any text subsequently added will be displayed upside down and to the right of the point of origin.

Please note that the pen position is ''not'' updated after this call.

Example:
<source lang="lsl">
// Example of osDrawText
default
{
state_entry()
{
string CommandList = ""; // Storage for our drawing commands

CommandList = osMovePen( CommandList, 10, 10 ); // Upper left corner at <10,10>
CommandList = osSetFontSize( CommandList, 10 ); // Use 10-point text
CommandList = osDrawText( CommandList, "Ten points!" ); // Place some text
CommandList = osMovePen( CommandList, 10, 27 ); // New text placement
CommandList = osSetFontSize( CommandList, 15 ); // Use 10-point text
CommandList = osDrawText( CommandList, "Fifteen points!" ); // Place some text
CommandList = osMovePen( CommandList, 10, 50 ); // New text placement
CommandList = osSetFontSize( CommandList, 20 ); // Use 10-point text
CommandList = osDrawText( CommandList, "Twenty points!" ); // Place some text

// Now draw the image
osSetDynamicTextureData( "", "vector", CommandList, "width:256,height:256", 0 );
}
}
