Gan_Image* gan_image_alloc (  Gan_ImageFormat  format, Gan_Type  type, unsigned long  height, unsigned long  width )

Macro: Allocate and return a new image. Allocates and returns a new image with given format (e.g. GAN_GREY_LEVEL_IMAGE, GAN_RGB_COLOUR_IMAGE), type (e.g. GAN_UCHAR for unsigned character images, GAN_DOUBLE for floating point images), height and width. Implemented as a macro call to gan_image_form_gen(). See also: gan_image_form().

Gan_Image* gan_image_alloc_b (  unsigned long  height, unsigned long  width )

Macro: Allocate and return a new grey-level image with type Gan_Bool. Returns: The allocated image, or NULL on failure. Allocate and return a new grey-level image of type Gan_Bool and given dimensions height and width. Implemented as a macro.

Gan_Image* gan_image_alloc_data (  Gan_ImageFormat  format, Gan_Type  type, unsigned long  height, unsigned long  width, void *  pix_data, size_t  pix_data_size, void *  row_data, size_t  row_data_size )

Macro: Allocate image. Allocates and returns an image with given format, type, dimensions height and width. If the provided pix_data and/or row_data pointers are NULL (in any combination), the pixel data array and/or the row start pointer array are dynamically allocated. If either are not NULL they must be big enough to hold the pixel/row pointer array data. If necessary use gan_image_data_size() to compute the necessary size of the pix_data array (the necessary size of row_data is height pointers). If you want to dynamically allocate the pixel data array and/or the row pointer array with sizes greater than that necessary for the given height and width, pass pix_data and/or row_data as NULL and set pix_data_size and/or row_data_size appropriately. Implemented as a macro call to gan_image_form_gen(). See also: gan_image_alloc() and gan_image_form().

Form image. Forms and returns an image img with given format, type, dimensions height and width. If the provided pix_data and/or row_data pointers are NULL (in any combination), the pixel data array and/or the row start pointer array are dynamically allocated.

The stride indicates the separation in memory between adjacent rows of the image, and is measured in bytes. Without any padding of the image it will correspond to width pixels, in which case you should use the gan_image_form_data() macro instead. If you want to dynamically allocate the pixel data array and/or the row pointer array with sizes greater than that necessary for the given height and width, pass pix_data and/or row_data as NULL and set pix_data_size and/or row_data_size appropriately.
