* pika_text_font:
|
|
* @image: The image.

|
* @drawable: (nullable): The affected drawable: (%NULL for a new text layer).
|
|
* @x: The x coordinate for the left of the text bounding box.

|
* @y: The y coordinate for the top of the text bounding box.
|

* @text: The text to generate (in UTF-8 encoding).

* @antialias: Antialiasing.
|
|
* @size: The size of text in pixels.
|
|
* @font: The font.
|
|
*
|
|
* Add text at the specified location as a floating selection or a new
|
|
* layer.
|
|
*
|
|
* 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.
|
|
* The size is always in pixels. 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.
