Functions

Gan_Imagegan_image_set_gen_gl_ui (Gan_Image *img, unsigned long height, unsigned long width, unsigned long stride, Gan_Bool alloc_pix_data)
 Set format, type, dimension and stride attributes of an image.

Gan_Imagegan_image_form_gen_gl_ui (Gan_Image *img, unsigned long height, unsigned long width, unsigned long stride, Gan_Bool alloc_pix_data, unsigned int *pix_data, size_t pix_data_size, unsigned int **row_data, size_t row_data_size)
 Form an image with specific format, type, dimensions and stride.

Gan_Bool gan_image_get_active_subwindow_gl_ui (Gan_Image *image, Gan_ImageWindow *subwin)
 Computes bounding box of non-zero pixels in grey-level image.

unsigned int * gan_image_get_pixptr_gl_ui (Gan_Image *img, unsigned row, unsigned col)
 Return a pointer to a pixel from a grey-level unsigned int image.

unsigned int ** gan_image_get_pixarr_gl_ui (Gan_Image *img)
