Bitmap.
pitch
¶ The number of bytes taken by one bitmap row.
Includes padding.
The pitch is positive when the bitmap has a ‘down’ flow, and negative when it has an ‘up’ flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row.
Note that ‘padding’ means the alignment of a bitmap to a byte border, and FreeType functions normally align to the smallest possible integer value.
For the B/W rasterizer,
pitch
is always an even number.To change the pitch of a bitmap (say, to make it a multiple of 4), use
Bitmap.convert
. Alternatively, you might use callback functions to directly render to the application’s surface.
