vector osGetDrawStringSize(string contentType, string text, string fontName, integer 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. | |
| Threat Level | This function does not do a threat level check |
| Permissions | Use of this function is always allowed by default |
| Extra Delay | 0 seconds |
| Example(s) | |
// 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 ); } } | |
| Notes | |
| This function does not take in to account any font properties specified in the draw list when computing the bounds of the text to be rendered. | |
