Brief description of the drawings
Fig. 1 is the flow chart of image processing method provided in an embodiment of the present invention.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into
One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
With reference to the image processing method flow chart shown in Fig. 1, to image processing method provided in an embodiment of the present invention
It is described in detail.
As shown in figure 1, image processing method provided by the invention mainly comprises the following steps：
Step 101, user terminal obtains the first pictorial information, image credit information and rotation angle parameter.
User terminal in the present embodiment is specially intelligent television.User terminal obtains the first figure by data acquisition interface
Piece information.First pictorial information can be cached to the local pictorial information of local data base or be stored in net
Network pictorial information in network server.
Step 102, judge whether first pictorial information is local pictorial information according to the image credit information, such as
Fruit is then to perform step 103；Otherwise, step 108 is performed.
Wherein, image credit information is to can interpolate that the information in the specific source of pictorial information, such as path letter is locally stored
Breath or network storage routing information.According to image credit information can interpolate that out the first pictorial information be local pictorial information also
It is network pictorial information, if local pictorial information then performs step 103；If network pictorial information then performs step
108。
In a specific embodiment, the displaying of picture, during Loading Image, Glide are realized using ViewPager
Pictorial information buffered in internal memory can be preferentially loaded, if not having corresponding data in internal memory, data can be loaded by database.
Step 103, first pictorial information is shown according to the rotation angle parameter.
First pictorial information is source file pictorial information, rotation angle parameter be when the first pictorial information is shown according to
The parameter information that specific exhibition method needs.
In a specific embodiment, the displaying of picture is realized using ViewPager.
Triggering obtains the content that database preserves in Activity onCreate methods, passes through after obtaining data
Data acquisition system readjustment is arrived current Acitivity by onSuccess methods；
Entity class PhotoBean is defined, the set got is List<PhotoBean>, create and inherit
The ImageAdapter classes of PagerAdapter classes, ImageAdapter classes are ViewPager adapters, and set is passed to
ImageAdapter classes, to display data；
Data are loaded in ImageAdapter classes, obtain set List<PhotoBean>In corresponding to some
PhotoBean, picture is loaded out according to PhotoBean rotation angle parameter direction by Glide.
Step 104, the rotation instruction that remote control equipment is sent is received, according to the rotation instruction generation rotation information.
Wherein, remote control equipment is specially the remote control of intelligent television.User terminal receive remote control by " ↑ ", " ↓ ",
The rotation instruction that " ← ", " → " key are sent, the first pictorial information is carried out clockwise or counter-clockwise according to rotation instruction generation
It is rotated by 90 °, the rotation information of 180 degree.
In a preferred embodiment, when the rotation instruction instructs for the first rotation, according to the described first rotation
Instruction generation turns clockwise information.
Refer to specifically, the first rotation instruction can be specifically the rotation that user terminal reception remote control is sent by " ↑ " key
Order, the first pictorial information is turn 90 degrees according to dextrorotation according to rotation instruction generation, the rotation information of 180 degree.
In another preferred embodiment, when the rotation instruction instructs for the second rotation, according to the described second rotation
Turn instruction generation rotate counterclockwise information.
Refer to specifically, the first rotation instruction can be specifically the rotation that user terminal reception remote control is sent by " ↓ " key
Order, according to rotation information of the rotation instruction generation by the first pictorial information according to 90 degree of rotate counterclockwise, 180 degree.
In a specific embodiment, create and remote controller key is monitored in ZoomImageView classes, " ↑ " of remote control,
" ↓ " key carries out rotation process to picture；" ← ", " → " key switch picture or " return " key exits browsing pictures.
Step 105, rotation processing is carried out to first pictorial information according to the rotation information, obtains second picture letter
Breath and rotation status information.
Specifically, after the first pictorial information is rotated into second picture information according to rotation information, record rotation status letter
Breath, rotation status information specifically include：Direction of rotation information and rotation angle information.
In a specific embodiment, intelligent television receives the rotation instruction of " ↑ " key transmission of remote control, by the first figure
Piece information dextrorotation is turn 90 degrees, the second picture information after being rotated, at the same record rotation status information for clockwise,
90 degree.
Step 106, database is arrived into rotation status information storage.
By the storage of rotation status information into the related database of pictorial information, carried out when being easy to check next time rotating image
Call.
In a specific embodiment, rotation is preserved by updating picture entity PhotoBean direction parameters
Turn state.
Step 107, the second picture information is shown.
The second picture information that display obtains the rotation of the first pictorial information afterwards, without storing second picture information.
In a preferred embodiment, user terminal receives " return " instruction that remote control equipment is sent, and exits browse graph
After piece, again during browsing pictures, the idsplay order that remote control equipment is sent is received, according to idsplay order and rotation status information to the
One pictorial information carries out rotation processing, obtains second picture information；Show second picture information.
In a specific embodiment, PhotoBean entities are saved in by database by saveRotation methods
Database, PhotoBean entities are taken out by database when next time browses, convenient display data again.
Step 108, first pictorial information is saved in local data base.
When first pictorial information is network pictorial information, the first pictorial information is saved in local data base, so
Step 103 is performed afterwards.
Image processing method provided in an embodiment of the present invention, user terminal obtain the first pictorial information, image credit information
And rotation angle parameter；Judge whether first pictorial information is local pictorial information according to the image credit information, such as
Fruit is then to show first pictorial information according to the rotation angle parameter；Receive the rotation instruction that remote control equipment is sent, root
According to the rotation instruction generation rotation information；Rotation processing is carried out to first pictorial information according to the rotation information, obtained
To second picture information and rotation status information；Database is arrived into rotation status information storage；Show the second picture
Information.Image processing method provided by the invention, when being rotated to picture, only preserve the rotation status information of picture, nothing
Postrotational picture need to be saved in local, not to source file frequently read-write operation, optimize performance, improve user's body
