Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the application's protection.
In order to better understand the method that the embodiment of the present application provides, first by reference to the accompanying drawings convergent-divergent in prior art and the method playing up picture are described further below.As shown in Figure 1, be prior art convergent-divergent and the schematic diagram playing up picture, wherein, 1-1 part is the shape of source picture, and can find out, the corner in this source picture is all fillet, and its base place is irregular figure, and bottom line is with one piece of delta-shaped region.This source picture is when carrying out convergent-divergent, and no matter desirable Target Photo should, as shown in 1-2, be horizontal convergent-divergent, longitudinal convergent-divergent, or two-way convergent-divergent, and four fillets of the Target Photo obtained and the delta-shaped region on base all remain unchanged.And picture is carried out to the processing mode of full figure convergent-divergent, four fillets and delta area deformation can be caused, the picture of the Target Photo finally obtained probably as shown in 1-3 part.Visible, simple full figure convergent-divergent can cause Target Photo gross distortion.When carrying out Design Internet Applications exploitation in iOS operating system, a kind of image zooming and rendering intent of optimization can be used, under this approach, can top in first designated pictures, left end, the fixed area part of right-hand member and bottom, as shown in 1-4 part in Fig. 1, in user-interface design performance history, iOS application developer can end distance first in picture in designated pictures, namely in picture four straight lines to the distance of corresponding sides, by end apart from limiting top in picture, left end, the retaining zone of right-hand member and bottom, the Picture section of retaining zone remains unchanged before and after convergent-divergent, and only convergent-divergent is carried out to the pixel in the middle of figure or rectangular area, thus obtain desirable Target Photo after ensure that zoom operations.But this method is still not ideal enough to the zoom operations of some pictures, picture as shown in 1-5 part in Fig. 1, this picture center section includes an icon and some words, when convergent-divergent is carried out to this picture, desirable effect is after zoom operations, the icon of center section and the size of word and relative position are all held constant, and utilize above-mentioned convergent-divergent and rendering intent cannot obtain desirable Target Photo.
The embodiment of the present application provides a kind of application disposal route of picture in mobile terminal device more widely, the picture that can not only comprise fillet to corner carries out rationally effective zoom operations, cannot process for classic method, centre position includes one or more picture of not wishing the region of scaled operation change, also reasonable and effective zoom operations can be carried out, thus obtain desirable Target Photo, such as iOS can be applied to widely, Adriod, in the applied software development of the operating systems such as WindowsPhone, the picture of scaling requirements is had all to have broad applicability for multiple.Below the method is described in detail.
See Fig. 2, the embodiment of the present application provide firstly the disposal route of picture in a kind of mobile terminal device, and at least one dimension of source picture comprises convergent-divergent identification information, and the method can comprise the following steps:
S201: the convergent-divergent identification information reading source picture, determines the position of the Picture section of each zoom area in the picture of source, the Picture section of each retaining zone, and the original length of each zoom area in each dimension;
First, at least one dimension of source picture comprises convergent-divergent identification information, this convergent-divergent identification information can be source picture provider add in the picture of source.Which region this convergent-divergent identification information specifically has can convergent-divergent for indicating in picture, and which region needs to remain unchanged.
Concrete, the concrete manifestation form of convergent-divergent identification information can have multiple.Such as, wherein under a kind of implementation, this convergent-divergent identification information is at least one convergent-divergent tag line with length and location information, and each convergent-divergent tag line is positioned at least one dimension of source picture.Such as, convergent-divergent tag line can be added respectively in the edge of at least one dimension of source picture, and this convergent-divergent tag line have length information and the relevant positional information to source picture.Or under another kind of implementation, this convergent-divergent identification information is at least two bar coordinate points, and the connected mode information between the positional information of coordinate points and coordinate points.Such as, some coordinate points can be specified in the edge of each dimension of source picture, and can annexation between specified coordinate point and coordinate points.Such as, the convergent-divergent identification information of certain source picture comprises: the coordinate of coordinate points A, B, C, D in the direction of the x axis, and specified coordinate point A, B are one group, two end points of a wherein convergent-divergent tag line on x-axis direction, coordinate points C, D are another group, two end points of another convergent-divergent tag line on x-axis direction, etc.Like this, can determine that source picture is in the position of the convergent-divergent tag line comprised in each dimension and length according to these points.Wherein, same source picture can comprise many convergent-divergent tag lines in a dimension.
Such as, shown in Fig. 3, it is the schematic diagram of the source picture with convergent-divergent tag line.In the drawings, on the x-axis direction, upside of source picture and on y-axis direction, left side, some convergent-divergent tag lines are had respectively.In order to save space and be convenient to process, the width of convergent-divergent tag line is generally the width of 1 pixel.Convergent-divergent tag line in the picture of source, is mainly used in as the zoom area in the picture of differentiation source and retaining zone provide foundation.By convergent-divergent tag line, can be zoom area and retaining zone by whole source picture segmentation, wherein, zoom area includes the region that needs expand or reduce when carrying out convergent-divergent process to source picture, and retaining zone then remains unchanged in the process of convergent-divergent.
In actual applications, the convergent-divergent identification information of source picture may be used for the position in region that can be scaled in identification sources picture, can certainly be used for identifying the region remained unchanged before and after convergent-divergent.In the embodiment of the present application, the convergent-divergent tag line for region that can be scaled in identification sources picture is that example is introduced.When using the source picture with convergent-divergent identification information, first the convergent-divergent identification information of reading source picture is needed, the position of the Picture section of each zoom area in the picture of source, the Picture section of each retaining zone is determined with this, and the original length of each zoom area in each dimension.In two-dimensional coordinate system as shown in Figure 3, the positional information of each convergent-divergent tag line can represent with the start position coordinate of each convergent-divergent tag line and final position coordinate.And the length of each convergent-divergent tag line, can be calculated by start position coordinate and final position coordinate position coordinate.The length of each convergent-divergent tag line can represent by number of pixels, length as a convergent-divergent tag line is 20pixels, also can represent by metric unit, the length of a such as convergent-divergent tag line is 12mm, the representation of concrete employing can depending on the demand of development environment, and the embodiment of the present application is to this not restriction.Owing to only needing the related data of convergent-divergent tag line in the picture of use source, at the convergent-divergent tag line of the source of reading picture, after the length obtaining each convergent-divergent tag line and positional information, each described convergent-divergent tag line in the picture of source can be removed, so that each operating system is called the picture removing convergent-divergent tag line.
After the length and location information of convergent-divergent tag line determining source picture, can according to the positional information of convergent-divergent tag line, determine the Picture section of the zoom area in the picture of source, and the position of the Picture section of each retaining zone in the picture of source, the original length of each zoom area in each dimension can also be determined in addition.During specific implementation, according to the projection of convergent-divergent tag line in the picture main body of source, zoom area and the retaining zone of source picture can be determined, and then determine the Picture section that each region is corresponding.Concrete, be projected covered region, can zoom area be defined as, can be defined as retaining zone by the region that any projection covers.Each zoom area or retaining zone may correspond to a Picture section in the picture of source respectively.When after each zoom area determined in the picture of source or retaining zone, corresponding Picture section is also just determined.
Further illustrate below in conjunction with accompanying drawing, as shown in Figure 4, it is the first schematic diagram determining the zoom area of source picture and each Picture section of retaining zone according to convergent-divergent identification information.In Fig. 4, source picture includes two convergent-divergent tag lines up, and includes a convergent-divergent tag line in left side, by the projection of these convergent-divergent tag lines in picture main part, 15 regions can be determined, comprising 6 retaining zones, and 9 zoom area.In 9 zoom area, in x-axis, the convergent-divergent tag line determined zoom area that projects is horizontal zoom area, the y-axis convergent-divergent tag line determined zoom area that projects is longitudinal zoom area, and be in the region that in x-axis, the projection of convergent-divergent tag line projects with convergent-divergent tag line in y-axis simultaneously, region as shown in the 4-1 part in Fig. 4 is x-axis, the two-way zoom area of y-axis.
According to the positional information of convergent-divergent identification information, after determining the Picture section of the zoom area in the picture of source, the Picture section of each zoom area and correspondence, the coordinate of convergent-divergent tag line end points in two-dimensional coordinate system can be used, and the length of convergent-divergent tag line represents, such as zoom area or Picture section can be expressed as:
RECT(LeftTopPoint_x，LeftTopPoint_y，Width，Height)
As shown in Figure 5, for determining the second schematic diagram of the zoom area of source picture and each Picture section of retaining zone according to convergent-divergent identification information, in Fig. 5,5-1 region is a zoom area, and the coordinate of top left corner apex in two-dimensional coordinate system of this zoom area is (x
3, y
3), x-axis direction width is (x
4-x
3), the height in y-axis direction is (y
4-y
3), then 5-1 zoom area can be expressed as:
RECT(x
3，y
3，x
4-x
3，y
4-y
3)；
In like manner, in Fig. 5, the zoom area of 5-1 can be expressed as:
RECT(x
5，y
3，x
6-x
5，y
4-y
3)；
By that analogy, can by the zoom area in the picture of source and retaining zone, or each Picture section that source picture divides according to convergent-divergent identification information represents in this form.
S202: according to the size of described source picture, the size of Target Photo and the original length of each zoom area in each dimension, determine the scaling of the Picture section of each zoom area in corresponding dimension;
Wherein, the size of Target Photo can be need to determine according to the display of reality.Such as, for the background picture of bubble of chatting in chat tool, can according to the size comprising the number of character in the text of active user's input, the size etc. of character determines Target Photo, or for the text that the other user received sends, the size of Target Photo also can be determined according to the size etc. of the number of characters comprised in the text received, character.
Specifically when determining the scaling of each zoom area, can first according to the projection of the convergent-divergent tag line in the picture of source, determine the zoom direction of the Picture section of zoom area, as the zoom area of the 5-2 in Fig. 5, covered by the projection of convergent-divergent tag line in y-axis, thus when convergent-divergent, the Picture section of this zoom area only convergent-divergent in the vertical, the Picture section of this zoom area transversely has corresponding scaling; And the zoom area of 5-1, both covered by the projection of convergent-divergent tag line in x-axis, covered by the projection of convergent-divergent tag line in y-axis again, the Picture section in this region is when convergent-divergent, zoom operations can be decomposed into horizontal convergent-divergent and longitudinal convergent-divergent two operation, and thus the Picture section of this zoom area has corresponding scaling respectively on horizontal and vertical.
The Picture section size of the retaining zone in the picture of source remains unchanged before and after convergent-divergent, and the Picture section of zoom area, can zoom in or out according to a certain percentage.Due to before and after convergent-divergent, the ratio regular meeting that the Picture section of each zoom area accounts for full figure changes, the scaling that the Picture section of each zoom area is corresponding, can not simply determine with the ratio of source picture and Target Photo.Therefore, in the embodiment of the present application, can according to the size of the size of source picture, Target Photo and each zoom area the original length in each dimension, determine the scaling of the Picture section of each zoom area in corresponding dimension.Below how to determine that the horizontal scaling of the Picture section of zoom area is introduced, longitudinal scaling of the Picture section of zoom area also can use similar method to determine.Refer to Fig. 6, for determining the schematic diagram of the horizontal scaling of the Picture section of zoom area.As shown in Figure 6, Image to left is the source picture with tag line, and right side is the Target Photo after zoom operations, and the length of convergent-divergent tag line can represent the wide of corresponding zoom area or Picture section.Before and after convergent-divergent, the width w of each retaining zone
1, w
2, w
3all remain unchanged, moreover, the ratio of the width of each zoom area of source picture and the overall width in image zooming region, source, the ratio of the width of Picture section and the overall width of target scale part after convergent-divergent corresponding on Target Photo, these two ratios are equal, and these two ratios can be expressed as shown in Figure 6:
L1/(L1+L2)＝L1’/(L1’+L2’)；
L2/(L1+L2)＝L2’/(L1’+L2’)；
If source picture width is L0, Target Photo picture width is L0 ', then the overall width in source image zooming region can use (L0-w
1-w
2-w
3) mark, the overall width of target scale part can with (L0 '-w
1-w
2-w
3) identify, like this, in the picture of source, the scaling of each zoom area can be expressed as
(L0-w
1-w
2-w
3)/(L0’-w
1-w
2-w
3)
According to this scaling, width in the horizontal after the Picture section convergent-divergent of each zoom area of source picture can be determined.In a similar manner, the Picture section of each zoom area of source picture height in the vertical after convergent-divergent can also be determined.Determining that the scaling that the Picture section of each zoom area of source picture is corresponding (comprises scaling transversely, and/or the scaling in longitudinal direction) after, can to the scaling according to correspondence, zoom operations is carried out to the Picture section of zoom area each in the picture of source, Picture section after the convergent-divergent that generation is corresponding.
S203: according to described scaling, carries out zoom operations to the Picture section of zoom area each in the picture of source, Picture section after the convergent-divergent that generation is corresponding;
Concrete, first can determine the scaling that the Picture section of each zoom area of source picture is corresponding in the first dimension, and determine the scaling that the Picture section of each zoom area of source picture is corresponding in the second dimension; When carrying out zoom operations to the Picture section of each zoom area, judge the scaling that photo current part is corresponding in the first dimension, and whether corresponding scaling is 1 in the second dimension; At scaling be not 1 dimension on, according to the scaling of correspondence, zoom operations is carried out to the Picture section in current zoom region.In two-dimensional direct angle coordinate system, the first dimension and the second dimension can be respectively horizontal x direction and longitudinal y direction.
S204: determine the target location of Picture section in Target Photo after the Picture section of each retaining zone of source picture and each convergent-divergent;
Carry out the convergent-divergent of corresponding ratio at the Picture section of each zoom area to source picture, to generate after corresponding convergent-divergent after Picture section, Picture section after convergent-divergent can be determined, and the position of the Picture section of each retaining zone in Target Photo.Specifically when determining the position of each Picture section in Target Photo, owing to being in drift angle Picture section corresponding to picture corner position, its position is relatively easily determined, first can determine the target location of drift angle Picture section in Target Photo that picture any one corner position in source is corresponding; Wherein, according to the difference that practical application needs, drift angle Picture section can be the Picture section that source picture is positioned at the retaining zone of corner position, also can be Picture section after the convergent-divergent that corner position is corresponding.And then according to the adjacent position relation between the described target location of this drift angle Picture section, each Picture section and size, determine the target location of the Picture section of each retaining zone in Target Photo successively, and the target location of Picture section in Target Photo after each convergent-divergent.
S205: according to the Picture section of each retaining zone of source picture and the target location in Target Photo thereof, and Picture section and the target location in Target Photo thereof after each convergent-divergent, generate Target Photo.
After determining the position of each Picture section in Target Photo, can according to the Picture section of each retaining zone of source picture and the target location in Target Photo thereof, and Picture section and the target location in Target Photo thereof after each convergent-divergent, generate Target Photo.Different implementations can be had during specific implementation.Wherein, blank painting canvas picture first can be set up, and then successively by the Picture section of each for source picture retaining zone, and Picture section after each convergent-divergent, be filled into target location corresponding in blank painting canvas picture respectively, generate described Target Photo.Wherein, the painting canvas of this blank can create according to the size of Target Photo, and can be a rectangle, its length and width can be identical or bigger with the maximum length of Target Photo on x-axis, y-axis direction.Under the preferred implementation of one, the painting canvas picture of this blank can have transparent background, or when the main interface background look of software is certain solid color, also the painting canvas of this blank can be created as with main interface background look identical, the display not being filled full regional effect Target Photo in blank canvas picture can be avoided like this.
Or, when Target Photo size is greater than source dimension of picture, when namely amplification generation Target Photo being carried out to source picture, also first painting canvas extended operation can be carried out to source picture, so-called painting canvas extended operation, refer to Fig. 7, for the schematic diagram of the source picture painting canvas expansion of the embodiment of the present application, first any one summit of source picture can be defined as expanding starting point, then to expand starting point for initial point, expansion in one or two dimension is carried out to source picture, source picture is expanded to Target Photo size, and before and after expansion, picture each pixel in maintenance source is relative to the invariant position of expansion starting point, remaining region, namely not by region that source picture pixels covers, can fill by Transparent color or specific color (interface background look as main in software), to keep the unification of look & feel.And then each Picture section is filled in the Target Photo after painting canvas expansion.Under this implementation, in order to avoid the part of Picture section to rear filling of first filling impacts, first from the region of the diagonal position of expansion starting point, can fill successively.Namely first can determine to expand in the picture of source the target location of drift angle Picture section in Target Photo that the vertical angle position of starting point is corresponding, then successively by the Picture section of each for source picture retaining zone, and Picture section after each convergent-divergent, be filled into corresponding target location respectively, generate Target Photo.In addition, when Target Photo size is less than source dimension of picture, can from the arbitrary corner position of source picture, successively by the Picture section of each for source picture retaining zone, and after each convergent-divergent, Picture section is filled into the correspondence position of source picture respectively; Then the region be not filled is removed, and using the picture that obtains after removing as Target Photo.Under this two all implementation, can the painting canvas picture of newly-built blank, there is the effect of certain saving memory headroom.
In addition, when source picture only has a zoom area, some system platforms, such as, in iOS operating system, can carry out carrying out convergent-divergent to source picture by the preset interface function of calling system, generate corresponding Target Photo, therefore, in the positional information according to the described convergent-divergent tag line read, determine the Picture section of each zoom area in the picture of source, and after the Picture section of each retaining zone, the number of zoom area in the picture of source can also be obtained; If the number of zoom area only has one in the picture of source, and the operating system that mobile terminal device carries is iOS operating system, then the interface function that calling system is preset carries out convergent-divergent to source picture, generates corresponding Target Photo.Otherwise, if the number of zoom area is two or more in the picture of source, then according to the positional information of the described convergent-divergent tag line read, determine the Picture section of two or more zoom area in the picture of source, and then perform follow-up step S203 to S206, generate Target Photo.
