Declaration [src]

gboolean
shumate_vector_sprite_sheet_add_page (
  ShumateVectorSpriteSheet* self,
  GdkTexture* texture,
  const char* json,
  double default_scale,
  GError** error
)

Description [src]

Adds a page to the spritesheet.

See https://maplibre.org/maplibre-gl-js-docs/style-spec/sprite/ for details about the spritesheet format. Most stylesheets provide these files along with the main style JSON.

Map styles should provide a double resolution spritesheet for high DPI displays. That spritesheet should be added as its own page, with a default_scale of 2.

Available since: 1.1

Parameters

texture

Type: GdkTexture

A GdkTexture.

The data is owned by the caller of the method.
json

A JSON string.

The data is owned by the caller of the method.

default_scale

Type: double

The default scale factor of the page.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the page was added successfully, FALSE otherwise.
