resize() 関数のヘルプ:
resize(clip, newsize=None, height=None, width=None, apply_to_mask=True)
| Returns a video clip that is a resized version of the clip.
|
| Parameters
| ------------
|
| newsize:
| Can be either
| - ``(height,width)`` in pixels or a float representing
| - A scaling factor, like 0.5
| - A function of time returning one of these.
|
| width:
| width of the new clip in pixel. The height is then computed so
| that the width/height ratio is conserved.
|
| height:
| height of the new clip in pixel. The width is then computed so
| that the width/height ratio is conserved.
|
| Examples
| ----------
|
| >>> myClip.resize( (460,720) ) # New resolution: (460,720)
| >>> myClip.resize(0.6) # width and heigth multiplied by 0.6
| >>> myClip.resize(width=800) # height computed automatically.
| >>> myClip.resize(lambda t : 1+0.02*t) # slow swelling of the clip
すべての例を試しました: resize( (width,height) ), resize(domsampling), resize(width=800), resize(lambda t : 1+0.02*t). しかし、それらのすべてが同じエラーを取得しています。
