Instance Method Details

FindFirstUnusedColour(startR=1, startG=0, startB=0)

Find first colour that is not used in the image and has higher RGB values than startR, startG, startB. Returns a tuple consisting of a success flag and rgb values.

Parameters:: startR
(type=int); startG
(type=int); startB
(type=int)

Returns:: (success, r, g, b)

GetCount(*args, **kwargs)

GetCount(self, unsigned long key) -> unsigned long

Returns the pixel count for the given key. Use MakeKey to create a key value from a RGB tripple.

GetCountColour(self, colour)

Returns the pixel count for the given wx.Colour value.

Parameters:: colour
(type=Colour)

Returns:: unsigned long

GetCountRGB(self, r, g, b)

Returns the pixel count for the given RGB values.

Parameters:: r
(type=byte); g
(type=byte); b
(type=byte)

Returns:: unsigned long

Static Method Details

MakeKey(r, g, b)

Get the key in the histogram for the given RGB values

Parameters:: r
(type=byte); g
(type=byte); b
(type=byte)

Returns:: unsigned long
