As a computation unit for processing images, it can resize an image to user-specified size.
It interpolates pixels when image is stretched, and discards pixels when image is compressed.
enum | ResizeOp.ResizeMethod | Algorithms for resizing. |
ResizeOp(int targetHeight, int targetWidth, ResizeOp.ResizeMethod resizeMethod)
Creates a ResizeOp which can resize images to specified size in specified method.

int |
getOutputImageHeight(int inputImageHeight, int inputImageWidth)
Computes the height of the expected output image when input image size is given.
|
int |
getOutputImageWidth(int inputImageHeight, int inputImageWidth)
Computes the width of the expected output image when input image size is given.

PointF |
inverseTransform(PointF point, int inputImageHeight, int inputImageWidth)
Transforms a point from coordinates system of the result image back to the one of the input
image.

targetHeight | The expected height of resized image. |
---|---|
targetWidth | The expected width of resized image. |
resizeMethod | The algorithm to use for resizing. Options: ResizeOp.ResizeMethod
|
Applies the defined resizing on given image and returns the result.
Note: the content of input image
will change, and image
is the same instance
with the output.
