Description
Technical field
The present invention relates to technical field of image processing, and in particular to a kind of icon synthetic method.
Background technology
Icon synthesized by the icon text importing synthetic method of existing mobile terminal desktop is more stiff, and style is widely different
It is different, ununified sense.Chinese publication CN102622163A discloses a kind of icon generation method, and it is first by primary icon
It is adjusted to size set in advance and calculates the dominant hue of primary icon, background colour is then generated according to the dominant hue,
The background colour is applied mechanically into gradual change template generation icon bottom plate, finally the icon after adjustment cut, the icon bottom
Icon and a preset icon foreground template after plate, cutting are superimposed, and generate final icon, are synthesized by the method
Although icon style it is unified, the dominant hue that calculate icon generates corresponding icon bottom plate and merged again, step ratio
It is cumbersome.
The content of the invention
The purpose of the present invention, it is exactly overcome the deficiencies in the prior art, there is provided one kind is quickly and easily cut icon
To reach the unified icon synthetic method of style.
In order to achieve the above object, adopt the following technical scheme that：A kind of icon synthetic method, comprises the following steps：
S1, obtain icon original image；
S2, the content for extracting icon original image, obtain each border midpoint of picture material；
S3, the vertical range for calculating each border midpoint of picture material and image boundary；
Whether each border midpoint of S4, comparison image content is identical or poor in pre-determined distance with the distance value on icon image border
In the range of value, if so, being determined as regular image, it is cut；If it is not, then it is determined as irregular image, with preset icon
Base merges；
S5, regular image is cut, travel through icon image content boundaries pixel, find out the extreme coordinates position on each border
Put；
S6, judge whether the extreme coordinates value of adjacent boundary is identical, if identical, without cutting, with default masking-out figure
As merging；If differing, the arc radius of adjacent boundary connection is calculated according to the extreme coordinates value of adjacent boundary, and
The midpoint of circular arc is calculated according to the radiuscope of circular arc；
S7, using the midpoint of each circular arc as end points, be attached successively and draw and finally cut cutting for icon original image
Scope, and icon original image is cut；
S8, the icon image cut and default masking-out image merged.
Further, the concrete operations of the content of extraction icon original image are in the step S2：Travel through icon original graph
Each pixel of picture, judges whether each pixel transparent angle value exceedes preset value, if exceeding preset value, is determined as non-icon figure
As content, if being no more than preset value, it is determined as icon image content.
Further, the concrete operations at each border midpoint of acquisition picture material are in the step S2：Obtain in icon image
Hold the extreme coordinates value on each border, the intermediate point for taking both ends point coordinates is the midpoint on each border.
Further, methods described is further comprising the steps of：
Before step S4, judge that each border midpoint of picture material is relative with the ultimate range in the vertical range of image boundary
Whether it is more than preset ratio value in the ratio value of whole icon image, if so, then entering step S4, if it is not, need not then be cut out
Cut and merged with default masking-out image.
Further, icon image content boundaries pixel is traveled through in the step S5, finds out the extreme coordinates position on each border
Concrete operations be：Using each border midpoint of picture material as starting point, traveled through to the left, to the right, judged one by one current respectively
Whether pixel transparent angle value exceedes preset value, if being no more than preset value, judges valid pixel and records coordinate position, continue to sentence
Disconnected next pixel transparent angle value；If exceeding preset value, it is determined as inactive pixels, stops time to next pixel transparent angle value
Go through, and record endpoint location of the coordinate position of the previous pixel of the pixel as border.
Further, the concrete operations merged the icon image cut and default masking-out image in the step S8
For：Masking-out image object is drawn on identical canvas object, in drawing process, the specified excessive pattern of rendered object is：Only
The icon image finally shown is drawn in the disjoint place of icon image and masking-out image, to realize synthesis.
Compared with prior art, the beneficial effects of the present invention are：The present invention is by obtaining icon original image；Extraction figure
The content of original image is marked, obtains each border midpoint of picture material；Calculate hanging down for each border midpoint of picture material and image boundary
Straight distance；Whether each border midpoint of comparison image content is identical with the distance value on icon image border or in pre-determined distance difference model
In enclosing, if so, being determined as regular image, it is cut；If it is not, then it is determined as irregular image, with preset icon base
Merge；Regular image is cut, travels through icon image content boundaries pixel, finds out the extreme coordinates position on each border
Put；Judge whether the extreme coordinates value of adjacent boundary is identical, if identical, without cutting, closed with default masking-out image
And；If differing, the arc radius of adjacent boundary connection is calculated according to the extreme coordinates value of adjacent boundary, and according to circular arc
Radiuscope calculate the midpoint of circular arc；Using the midpoint of each circular arc as end points, it is attached successively and draws and final cut icon original
Beginning image cuts scope, and icon original image is cut；The icon image cut and default masking-out image are entered
Row merges；Quickly and easily icon is cut unified to reach style.
