### gimp_text_layer_new ()

    gint32
    gimp_text_layer_new (gint32 image_ID,
                         const gchar *text,
                         const gchar *fontname,
                         gdouble size,
                         GimpUnit unit);

Creates a new text layer.

This procedure creates a new text layer. The arguments are kept as simple as necessary for the normal case. All text attributes, however, can be modified with the appropriate gimp_text_layer_set_*() procedures. The new layer still needs to be added to the image, as this is not automatic. Add the new layer using `gimp_image_insert_layer()`.

#### Parameters

image_ID | The image. |
text | The text to generate (in UTF-8 encoding). |
fontname | The name of the font. |
size | The size of text in either pixels or points. |
unit | The units of specified size. |

#### Returns

The new text layer.

Since: 2.6
