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
|
|
(-1), 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.

|
|
This tool requires font information in the form of nine parameters: size,
|
|
foundry, family, weight, slant, set_width, spacing, registry, encoding. The
|
|
font size can either be specified 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 antialias parameter is
|
|
non-zero, the generated text will blend more smoothly with underlying layers.
|
|
This option requires more time and memory to compute than non-antialiased text;
|
|
the resulting floating selection or layer, however, will require the same
|
|
amount of memory with or without antialiasing. 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 (-1), 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. If the border is specified
|
|
as -1, empty spaces around the text will not be cropped.
