Function Documentation

Gan_Bool gan_edge_feature_display (  Gan_EdgeFeature *    edge, float    size, Gan_Matrix23_f *    A, Gan_RGBPixel_f *    edge_colour )

Displays a single edge feature. Parameters: edge  A edge feature size  The size of cross to draw on the display A  Affine transformation to apply to feature coordinates edge_colour  The colour to display the feature Displays a single edge feature. If size is passed as zero, the edge is drawn as a point with current point size. Otherwise the edge as drawn as a cross of the given size. Returns: GAN_TRUE on success, GAN_FALSE on failure.

Gan_Bool gan_edge_feature_map_display (  Gan_EdgeFeatureMap *    emap, float    size, Gan_Matrix23_f *    A, Gan_RGBPixel_f *    edge_colour, Gan_RGBPixel_f *    string_colour, Gan_RGBPixel_f *    first_colour, Gan_RGBPixel_f *    last_colour, Gan_RGBPixel_f *    bbox_colour )

Displays a edge feature map. Parameters: emap  The edge feature map size  The size of cross to draw on the display A  Affine transformation to apply to feature coordinates edge_colour  The colour to display the features string_colour  The colour to display any strings first_colour  The colour to display the start of a string last_colour  The colour to display the end of a string bbox_colour  The colour to display the bounding box Displays a edge feature map. If size is passed as zero, the edge is drawn as a point with current point size. Otherwise the edge as drawn as a cross of the given size. Returns: GAN_TRUE on success, GAN_FALSE on failure.
