fp_image_new ()

FpImage *
fp_image_new (gint width,
              gint height);

fp_image_get_width ()

guint
fp_image_get_width (FpImage *self);

Gets the pixel width of an image.

fp_image_get_height ()

guint
fp_image_get_height (FpImage *self);

Gets the pixel height of an image.

fp_image_get_ppmm ()

gdouble
fp_image_get_ppmm (FpImage *self);

Gets the resolution of the image. Note that this is assumed to be fixed to 500 points per inch (~19.685 p/mm) for most drivers.

fp_image_get_minutiae ()

GPtrArray *
fp_image_get_minutiae (FpImage *self);

Gets the minutiae for an image. This data must not be modified or freed. You need to first detect the minutiae using fp_image_detect_minutiae().

fp_image_detect_minutiae ()

void
fp_image_detect_minutiae (FpImage *self,
                          GCancellable *cancellable,
                          GAsyncReadyCallback callback,
                          gpointer user_data);

Detects the minutiae found in an image.

fp_image_detect_minutiae_finish ()

gboolean
fp_image_detect_minutiae_finish (FpImage *self,
                                 GAsyncResult *result,
                                 GError **error);

Finish minutiae detection in an image

fp_image_get_data ()

const guchar *
fp_image_get_data (FpImage *self,
                   gsize *len);

Gets the greyscale data for an image. This data must not be modified or freed.

fp_image_get_binarized ()

const guchar *
fp_image_get_binarized (FpImage *self,
                        gsize *len);

Gets the binarized data for an image. This data must not be modified or freed. You need to first detect the minutiae using fp_image_detect_minutiae().

fp_minutia_get_coords ()

void
fp_minutia_get_coords (FpMinutia *min,
                       gint *x,
                       gint *y);

Returns the coordinates of the found minutia. This is only useful for debugging purposes and the API is not considered stable for production.
