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"

"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."
