/**

* @x: The x coordinate for the left of the text bounding box.

|

|
* @border: The size of the border.
|
||
|
* @antialias: Antialiasing.
|
||
|
* @size: The size of text in either pixels or points.
|
||
|
* @size_type: The units of specified size.
|
||
|
* @fontname: The name of the font.
|
||
|
*
|
||
|
* Add text at the specified location as a floating selection or a new
|
||
|
* layer.
|
||
|
*
|
||
|
* This tool requires a fontname matching an installed PangoFT2 font.
|
||
|
* You can specify the fontsize in units of pixels or points, and the
|
||
|
* appropriate metric is specified using the size_type argument. The x
|
||
|
* and y parameters together control the placement of the new text by
|
||
|
* specifying the upper left corner of the text bounding box. If the
|
||
|
* specified drawable parameter is valid, the text will be created as a
|
||
|
* floating selection attached to the drawable. If the drawable
|
||
|
* parameter is not valid (%NULL), the text will appear as a new layer.
|
||
|
* Finally, a border can be specified around the final rendered text.
|
||
|
* The border is measured in pixels. Parameter size-type is not used
|
||
|
* and is currently ignored. If you need to display a font in points,
|
||
|
* divide the size in points by 72.0 and multiply it by the image's
|
||
|
* vertical resolution.
|
||
|
*
|
||
|
* Returns: (nullable) (transfer none):
|
||
|
* The new text layer or %NULL if no layer was created.
