Limited.On the contrary, there is provided these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure
Complete conveys to those skilled in the art.
The embodiment of the present invention provides a kind of method for Loading Image, and is applied in the electronic equipment comprising display unit, its
In, correspondingly there is display unit a viewing area, electronic equipment can adopt ARIXTRA (Android) system.As shown in figure 1, institute
The method of stating is comprised the following steps：
Step 101：Obtain the image resolution ratio of Target Photo and the display of the viewing area for display target picture
Resolution.
Step 102：Judge image resolution ratio whether more than display resolution.
Step 103：When image resolution ratio is more than display resolution, Target Photo is divided into some picture fragments.
Specifically, for the segmentation of Target Photo, in a kind of specific embodiment, first, based on Target Photo
Memory capacity, determine total dividing number of Target Photo.Generally, shown in the display unit of Android device
The preferable capacity range for storage of single picture is 500Kb～1Mb, therefore, it can determine that in the range of preferable storage one is default single
Individual picture fragment memory capacity, such as 800Kb.So as to when the memory capacity of the every pictures fragment being partitioned into all is controlled default
During single picture fragment memory capacity, the picture being made up of some picture fragments will have more preferable display effect.
Further, according to the memory capacity of the memory capacity and default single picture fragment of Target Photo, determine target
Total dividing number of picture.Wherein, the memory capacity of Target Photo can pass through to obtain in Target Photo attribute information.Wherein,
Formula for determining total dividing number of Target Photo is as follows：Wherein, memory capacity of the A for Target Photo, B is pre-
If the memory capacity of single picture fragment, total dividing number of the C for Target Photo.
During application above-mentioned formula, the memory capacity of the memory capacity of Target Photo and default single picture fragment
Unit need to be consistent, if both units are inconsistent, need first to carry out unit conversion, for example, if Target Photo storage hold
The unit of amount be Mb, and preset single picture fragment memory capacity unit be Kb when, can by the unit of Target Photo turn
It is changed to Kb.If the numerical value bag for the obtaining in addition, memory capacity of Target Photo is divided by with the memory capacity for presetting single picture fragment
Containing remainder, then by remainder carry, so that total dividing number of Target Photo is integer, for example, the memory capacity of Target Photo
For 23Mb, the memory capacity of presetting single picture fragment is 800Kb, then total dividing number of the Target Photo for obtaining after carry is
30, total dividing number of the Target Photo for finally giving is the total quantity for needing to be divided into Target Photo picture fragment.
It should be noted that the preferable memory capacity of single picture fragment correspondingly shown by different display units can
Can be different, those skilled in the art can determine the memory capacity for presetting single picture fragment according to practical situation, for example, select
Memory capacity of the 1Mb as default single picture fragment, or, select 500K to hold as the storage for presetting single picture fragment
Amount, the application are not limited.
Further, as picture is generally shown according to certain Aspect Ratio, therefore, the total score of Target Photo is being obtained
After cutting quantity, based on total dividing number and the length-width ratio of Target Photo, first point in the longitudinal direction of Target Photo is determined
Cut quantity and Target Photo the second dividing number in the direction of the width.For example, the length-width ratio of Target Photo is 4: 3, calculates
Total dividing number of the Target Photo for going out is 30, then, for determine the first dividing number and the second dividing number formula such as
Under：
Wherein, D is Target Photo the first dividing number in the longitudinal direction, E be Target Photo in the direction of the width
Second dividing number, length-width ratios of the F for Target Photo.Wherein, during application above-mentioned formula, if the first dividing number
There is remainder with the second dividing number, equally, by remainder carry so that the first dividing number and the second dividing number be whole
Number.
Further, Target Photo is split according to the first dividing number and the second dividing number.Specifically, each figure
The computing formula of the length of piece fragment and the width of each picture fragment is as follows：
Wherein, G is the length of each picture fragment, and H is the width of each picture fragment, and Fl is the length of Target Photo,
Width of the F2 for Target Photo.So as to Target Photo just can be divided into phase by the length and width according to every pictures fragment
The equal portions that answers.
In specific implementation process, Target Photo can be calculated in length direction according to the Math functions in Android
With the quantity of the picture fragment that splits on width, further, the sqrt functions in needing using Math when calculating ask flat
Root, specifically, tries to achieve the first dividing number and the second dividing number using sqrt functions, due to the first dividing number that tries to achieve
It is double with the type of the second dividing number, the type of picture fragment should be integer, the ceil in therefore, it can using Math
Function carry is rounded.In the same manner, it is also possible to which total dividing number carry of the ceil function pair Target Photos in using Math is rounded.
In this application, during the first dividing number and the second dividing number is determined, if the first dividing number and
There is remainder in the second dividing number, then after segmentation object picture, according to the first dividing number after rounding, after rounding second
Dividing number and the size of Target Photo, to segmentation after Target Photo be left white.Wherein, position is left white positioned at Target Photo
Surrounding.Specifically, there is remainder in the first dividing number when Target Photo in the longitudinal direction, then, splitting number by first
Measure whole after, by rounding after the first dividing number be multiplied by the length of every pictures fragment after deduct the length of Target Photo
Degree, obtain Target Photo in the longitudinal direction be left white size.When Target Photo the second dividing number in the direction of the width is deposited
In remainder, then, after the second dividing number is rounded, by rounding after the second dividing number be multiplied by every pictures fragment
Deduct the width of Target Photo after width, obtain Target Photo in the direction of the width be left white size.Finally, according to the mesh for obtaining
Mark on a map piece length direction be left white size and the size that is left white in the direction of the width is left white to the surrounding of Target Photo,
So that the picture ratio of the Target Photo being spliced by some picture fragments after segmentation is adapted to original object picture
Ratio.
When picture segmentation is carried out, it is possible to use the Bitmap.createBitmap in Android carrying out, after segmentation
Picture fragment save as bitmap forms, and store in ImageCache objects, the object includes 3 parameters, 3 parameters
Respectively：The position on long side, the position of picture fragment minor face in picture array in picture fragment picture array after singulation,
And the bitmap objects of picture fragment.After each picture fragment is respectively obtained, by the long side of each picture fragment and minor face
Position stored in corresponding ImageCache objects in the lump, and created spliced map later by convenient in list for object storage
Piece.Wherein, the schematic diagram of the Target Photo before splitting and after segmentation corresponds to Fig. 2 and Fig. 3 respectively.
