Description
Technical Field
The invention relates to the technical field of image (graph) display, in particular to a processing method of picture Gaussian blur under Mac. Mac refers to the apple computer (once translated to the Macintosh transliteration), running the OS X system (a proprietary operating system developed by apple for the Macintosh computer).
Background
In the process of image processing, Gaussian Blur (english: Gaussian Blur) is a more commonly used Blur algorithm, also called Gaussian smoothing, is a processing effect widely used in image processing software such as Adobe Photoshop, GIMP, and paint.
By "blurred" it is understood that each pixel is averaged over surrounding pixels. For example:
if the middle point (middle pixel point) is 2 and the peripheral 8 peripheral points (peripheral pixel points) are 1, then: the "middle point" is the average of the "peripheral points" and becomes 1.
Numerically, this is a kind of "smoothing". Graphically, it is equivalent to producing a "blur" effect, with the "middle point" losing detail. The larger the blur radius, the more blurred the image, and from a numerical perspective, the smoother the value.
In the OS X system, a gaussian semi-transparent View control nsvisual effect View has been provided, but the control only supports limited colors, and it is difficult to change colors, so that it is inconvenient to implement gaussian blur display of a picture with the control, and it is also impossible to implement switching from a gaussian picture to a normal picture display.
