) -> *mut fz_image

Internal function to make a new fz_image structure for a derived class.

w,h: Width and height of the created image.

bpc: Bits per component.

colorspace: The colorspace (determines the number of components, and any color conversions required while decoding).

xres, yres: The X and Y resolutions respectively.

interpolate: 1 if interpolation should be used when decoding this image, 0 otherwise.

imagemask: 1 if this is an imagemask (i.e. transparent), 0 otherwise.

decode: NULL, or a pointer to to a decode array. The default decode array is [0 1] (repeated n times, for n color components).

colorkey: NULL, or a pointer to a colorkey array. The default colorkey array is [0 255] (repeated n times, for n color components).

mask: NULL, or another image to use as a mask for this one. A new reference is taken to this image. Supplying a masked image as a mask to another image is illegal!

size: The size of the required allocated structure (the size of the derived structure).

get: The function to be called to obtain a decoded pixmap.

get_size: The function to be called to return the storage size used by this image.

drop: The function to be called to dispose of this image once the last reference is dropped.

Returns a pointer to an allocated structure of the required size, with the first sizeof(fz_image) bytes initialised as appropriate given the supplied parameters, and the other bytes set to zero.
