BUILT-IN MATHEMATICA SYMBOL
ImageRotate
ImageRotate[image]
rotates image counterclockwise by 90°.
ImageRotate[image, side]
rotates image to make the top of the image be on the specified side.
ImageRotate[image, side1->side2]
rotates image to make 
be on 
.
ImageRotate[image, 
]
rotates image counterclockwise by radians.
ImageRotate[image, side, size]
gives an image of the specified size.
- Possible side specifications are: Top, Bottom, Left, Right.
- ImageRotate[image, ...] rotates image about its center.
- ImageRotate yields an Image object with pixel values corresponding to a rotated image.
- ImageRotate[image, side] is equivalent to ImageRotate[image, Top->side].
- ImageRotate takes a Background option to specify the color assumed for pixels outside the image. With Background->Transparent, ImageRotate pads with fully transparent black pixels.
- By default, ImageRotate automatically chooses the most suitable resampling algorithm. An explicit algorithm can be specified by setting the Resampling option.
- In ImageRotate[image, side, size], possible specifications for size include:
-
| w | width of the output image |
| {w,h} | width and height of the output image |
| Automatic | smallest rectangle to enclose all of the rotated image |
| All | smallest square to accommodate the rotated image for any rotation angle |
| Full | use the dimensions of the input image |
Rotate an image counterclockwise by 90 degrees:
| Out[1]= |  |
Rotate an image counterclockwise by 20 degrees:
| Out[1]= |  |
Turn a photo to the right:
| Out[1]= |  |
Turn the previous result so that the left side goes to the top:
| Out[2]= |  |
Pad the result to include the entire rotated image:
| Out[1]= |  |
