func (*MyImage) Congregate ¶

func (i *MyImage) Congregate(maxMoveDist int, numIters float64)

Modify the image in-place by swapping pixels to places where they match their neighbors. maxMoveDist is the max distance between two swapped pixels. If 0, there is no limit.

func (*MyImage) GetColorWithLinearInterpolation ¶

func (i *MyImage) GetColorWithLinearInterpolation(x float64, y float64) *mycolor.MyColor

Return an interpolated pixel value from the image. x and y values outside the image will return the value from the nearest point in the image.

func (*MyImage) SaveAs ¶

func (i *MyImage) SaveAs(path string)

func (*MyImage) ShowThumb ¶

func (i *MyImage) ShowThumb(thumbSize float64)

func (*MyImage) SortColumns ¶

func (i *MyImage) SortColumns(kind string, numThreads int)

Launch some threads to sort the rows of the image. Wait until complete, and kill the threads.

func (*MyImage) SortRows ¶

func (i *MyImage) SortRows(kind string, numThreads int)

Launch some threads to sort the rows of the image. Wait until complete, and kill the threads.

func (*MyImage) String ¶

func (i *MyImage) String() string

func (*MyImage) ThumbnailByPixels ¶

func (i *MyImage) ThumbnailByPixels(maxRes int) *MyImage

Return a new image which fits in a square of maxRes x maxRes pixels but keeps the same aspect ratio. If the image is already small enough, just return the same image again.

func (*MyImage) ThumbnailByRatio ¶

func (i *MyImage) ThumbnailByRatio(ratio float64) *MyImage

Return a new image which has a size of (ratio * original_image_size)

func (*MyImage) ToBuiltInImage ¶

func (i *MyImage) ToBuiltInImage() image.Image

Create an image using the built-in image.RGBA type and copy our pixels into it.
