The present application relates to the picture processing technologies for an intelligent terminal, and in particular, to a method and an electronic device for previewing a picture on an intelligent terminal.
With the continuous development of communication technologies, media information such as picture, music and video bring an excellent audio-visual experience to a user, and become one of the important component parts of mobile intelligent terminal systems.
Picture is a multimedia resource that is most frequently concerned by an intelligent terminal user. To improve the picture content effect and increase the information volume, the contents of network information are often present in a form of a long picture. In the case that a long picture is viewed in a preview mode in the operating system or application software of the intelligent terminal,
However, in the above long picture content reading mode of the prior art, a complete accuracy cannot be realized via the gesture operation of a user, and an excessive zoom-in operation is done so that the long picture presented on a preview window needs to be adjusted left and right to read the picture content, or the content presented on the preview window after the zoom-in operation of the long picture is not the part that the user wants to read, and thus the user needs to adjust the long picture presented on the preview window up and down or left and right, which may cause a poor reading experience to a user.

Referring to
Step 110: a picture to be previewed is acquired, and a picture type is identified;
In the present embodiment, a picture to be previewed may be acquired by performing an interactive operation (for example, clicking on a hyperlink or a thumbnail, etc.) with an intelligent terminal on a specified picture that is to be previewed. Optionally, after receiving a message triggered by the user operation, the picture browser acquires the corresponding picture to be previewed.
After acquiring the picture to be previewed, the picture type is identified at the beginning. Optionally, the picture type may include a common picture and an odd-shaped picture. The common picture refers to a picture of which a size fits the screen of the intelligent terminal or fits the picture preview window of a picture preview tool configured in the intelligent terminal, for example, a photo captured by the intelligent terminal device via a camera, or a picture acquired by the intelligent terminal via screen shot. The odd-shaped picture refers to a picture with a size that is largely different from the screen of the intelligent terminal or the picture preview window of a picture browse tool configured in the intelligent terminal, for example, a long picture acquired by the intelligent terminal via network download or Bluetooth transmission, etc., or a panoramic photo acquired by the intelligent terminal via camera shoot or network download, etc.
Optionally, the above two types of pictures may be distinguished according to a relation between the length-to-width ratio of the picture and a specified threshold. A picture with a length-to-width ratio greater than the specified threshold is identified as a common picture, and a picture with a length-to-width ratio less than the specified threshold is identified as an odd-shaped picture. Wherein, the selection of the specified threshold may be preset according to practical situation (for example, it may be preset by referring to the length-to-width ratio of the screen of a current mainstream intelligent terminal or the length-to-width ratio of a long picture that is popular on the network), which is not limited in the present embodiment.
It should be noted that, according to the arrangement mode of the picture content, the odd-shaped picture may be further divided into a horizontal odd-shaped picture and a vertical odd-shaped picture. When a reader normally reads a picture content, a picture with its long edge placed in the horizontal direction is a horizontal odd-shaped picture, such as the above panoramic photo; and a picture with its long edge placed in the vertical direction is a vertical odd-shaped picture, such as the above long picture.
Optionally, the type of the picture to be previewed may be identified by acquiring the attribute information of the picture or the size information of the picture.
Step 120: the size of a picture preview window is acquired if the picture type is an odd-shaped picture;
Generally, the content of an odd-shaped picture is abundant, containing a large amount of literal or graphic information. In order to conveniently read the picture information by a mobile terminal user, the odd-shaped picture needs to be zoomed by a reasonable ratio so that after zooming, the content of the odd-shaped picture which is displayed on a picture preview window is easy to read. Thus, it may be seen that, the zooming of an odd-shaped picture takes the size of the picture preview window as a reference. Therefore, after it is determined that the picture to be previewed is an odd-shaped picture, the size of the picture preview window is acquired so as to obtain the above reasonable ratio for zooming the odd-shaped picture.
Step 130: a zooming parameter for the odd-shaped picture is determined according to the size of a short edge of the odd-shaped picture and the size of a corresponding edge of the picture preview window.
The size of the long edge of the odd-shaped picture is much larger than the size of the short edge thereof, and hence only a part of the contents of the readable odd-shaped picture is displayed on the preview window. In order to read the picture content conveniently by a user and avoid the scroll operation in two directions when reading the picture content, the short edge of the odd-shaped picture becomes a limiting factor for zooming an odd-shaped picture.
Generally, the larger the font on a picture is, the more easily a reader reads. That is, the odd-shaped picture is zoomed under the premise that the readability of the odd-shaped picture is guaranteed. When the short edge of the odd-shaped picture after zooming is equal to the length of the corresponding edge of the picture preview window, the readability is the best, as shown in
Optionally, the determining a zooming parameter for the odd-shaped picture according to the size of a short edge of the odd-shaped picture and the size of a corresponding edge of the picture preview window may include the following steps of determining the size of an edge of the picture preview window corresponding to the short edge; calculating a ratio of the size of the short edge of the odd-shaped picture to the size of the corresponding edge of the picture preview window; and taking the ratio as the zooming ratio of the odd-shaped picture.
During the practical reading process, the condition is met as long as a reader can clearly see the content information of the picture easily. Therefore, the size of the odd-shaped picture after zooming is not limited to that the short edge of the odd-shaped picture is equal to the corresponding edge of the picture preview window, but also the short edge of the odd-shaped picture may be zoomed to slightly less than the length of the corresponding edge of the picture browser window. Then, a zooming parameter for the odd-shaped picture is determined according to the obtained ratio of the length of the short edge of the odd-shaped picture to the length of the corresponding edge of the picture preview window.
It should be noted that, for a horizontal odd-shaped picture, the edges of the picture preview window corresponding to the short edge of the horizontal odd-shaped picture are two edges in the vertical direction. For a vertical odd-shaped picture, the edges of the picture preview window corresponding to the short edge of the vertical odd-shaped picture are two edges in the horizontal direction.
Step 140: the odd-shaped picture is zoomed and displayed in the picture preview window according to the zooming parameter;
The odd-shaped picture is zoomed in equal proportion according to the zooming parameter, that is, the length and width of the odd-shaped picture are both zoomed correspondingly according to the zooming ratio, and then the odd-shaped picture after zooming is displayed in the picture preview window.
In the technical solution according to this embodiment, after a picture to be previewed is identified, a zooming parameter for the odd-shaped picture is determined according to the size of the short edge of the odd-shaped picture and the size of the corresponding edge of the picture preview window, and the odd-shaped picture is zoomed and displayed in the picture preview window according to the zooming parameter, thereby solving the problem of poor readability of the information of the odd-shaped picture caused by unsuitable display ratio, improving the readability of the odd-shaped picture, and raising and user reading experience.
On the basis of the above embodiment, after the zooming and displaying the odd-shaped picture on the picture preview window according to the zooming parameter, the method may further include: exhibiting a visualized identification of a scroll browse picture in the picture preview window.
The content of the odd-shaped picture after zooming cannot be fully displayed on the preview window, so that it needs to be scrolled along the long edge of the odd-shaped picture for content switching. In the present embodiment, a visualized identification is provided on the picture preview window for prompting a user that the picture viewed currently belongs to an odd-shaped picture, and the user may know the scroll reading direction by setting the attribute, such as shape and the like, of the visualized identification. For example, for a vertical odd-shaped picture, and a scroll bar or a virtual button with a direction indicator may be added to the right of the picture preview window.
With the above settings, the reading direction and the content switching method of the odd-shaped picture may be prompted rapidly and effectively, thus improving the readability of the odd-shaped picture and the user reading experience.
Based on the above Embodiment 1, the present embodiment provides a method for previewing a picture on an intelligent terminal.
Step 210: the size of a picture to be previewed is acquired, and a picture type is determined according to the size of the picture;
Optionally, the acquiring the size of the picture to be previewed and determining a picture type according to the size of the picture may include the following steps: a length size and a width size of the picture to be previewed is acquired; and it is determined that the picture type of the picture is an odd-shaped picture if a ratio of the length to the width is in a set value range.
In the present embodiment, the type of the picture to be previewed is determined according to the picture size. First of all, a picture browser acquires a length size and a width size of the picture to be previewed. Optionally, if the intelligent terminal is installed with an Android operating system, by invoking the class Option of BitmapFactory built in the Android system and setting the option in JustDecodeBounds in the class Option as “True”, the size and the aspect ratio of the picture to be previewed may be acquired during the decoding of the picture. Then, according to the length-to-width ratio of the picture to be previewed, it is judged whether the ratio is in a set value range. It should be noted that, usually a threshold may be set, and it is determined whether the picture is an odd-shaped picture by directly comparing the calculated ratio with the threshold.
The inventors find by researches that, if the threshold is set too small, many long pictures may be wrongly judged as common pictures, and if the threshold is set too large, a picture originally zoomed normally will be abnormal. Therefore, for the selection of a suitable threshold, it needs to guarantee that the reading experience will not be too poor even if a normal picture is zoomed as a long picture or a long picture is zoomed as a normal picture. In consideration of the above conditions and by investigating through selecting some long pictures (i.e., vertical odd-shaped pictures) from Microblog and Wechat as samples, ⅓ is finally selected as the threshold for distinguishing between common pictures and odd-shaped pictures.
That is, if the ratio of the length to the width of the picture to be previewed is less than or equal to one-third, it is determined that the picture to be previewed is an odd-shaped picture. Exemplarily, the ratio of the length to the width of the picture shown in
However, it may be understood that, the threshold for determining whether a picture to be previewed is a long picture is not limited to the above one-third, and it may also be other values and may be adjusted by a user, which is not limited in the present embodiment.
Step 220: the size of a picture preview window is acquired if the picture type is an odd-shaped picture;
Step 230: a zooming parameter for the odd-shaped picture is determined according to the size of a short edge of the odd-shaped picture and the size of a corresponding edge of the picture preview window; and
Step 240: the odd-shaped picture is zoomed and displayed in the picture preview window according to the zooming parameter.
In the technical solution according to the present embodiment, the size of a picture to be previewed is acquired, a length-to-width ratio is calculated according to the size, and it is determined that the picture to be previewed is an odd-shaped picture when it is judged that the ratio is in a set value rang, and a zooming parameter is determined, then the odd-shaped picture is zoomed and displayed in the picture preview window according to the zooming parameter, so that the picture type may be identified via the picture size, and a targeted zooming process may be performed on the identified odd-shaped picture, thereby solving the problem of poor readability of the information of the odd-shaped picture caused by unsuitable display ratio, improving the readability of the odd-shaped picture, and raising user reading experience.
On the basis of the above embodiment, after the zooming and displaying the odd-shaped picture in the picture preview window according to the zooming parameter, the method may further include the following steps: if the odd-shaped picture exits preview, the browse location of the odd-shaped picture in the picture preview window at the time of exiting preview is saved and a correspondence between the browse location and the odd-shaped picture is established; and the zooming parameter for the odd-shaped picture is saved.
Correspondingly, after acquiring the picture to be previewed, the method further includes the following steps: if it is searched that the corresponding browse location and zooming parameter of the picture to be previewed are stored locally, the picture to be previewed is displayed on the picture preview window according to the browse location and the zooming parameter.
Because the volume of the information of an odd-shaped picture is large, in many cases, the content of the odd-shaped picture cannot be read in one time, thus in the present embodiment, it will be set differently when the odd-shaped picture is opened for the first time and when the odd-shaped picture is opened again, respectively.
If the picture browser judges that no related information of the current odd-shaped picture is stored locally, it is determined that the current odd-shaped picture is previewed for the first time. When the odd-shaped picture is opened for the first time, the user tends to read the picture information from the beginning. In the present embodiment, after the current odd-shaped picture is zoomed according to the obtained zooming parameter, the upper edge of the current odd-shaped picture (a vertical odd-shaped picture) or the left edge of the current odd-shaped picture (a horizontal odd-shaped picture) is identified, and when the current odd-shaped picture is displayed in the picture preview window, the upper edge (vertical odd-shaped picture) or the left edge (horizontal odd-shaped picture) is made to coincide with the upper edge (vertical odd-shaped picture) or the left edge (horizontal odd-shaped picture) of the picture preview window.
If the picture browser judges that the related information of the current odd-shaped picture is stored locally, it determined that the current odd-shaped picture is previewed again. When the odd-shaped picture is opened again, the user tends to continue with the information unread in last time; as directed to such a problem, in the present embodiment, when the odd-shaped picture exits preview, the current reading location information and the zooming parameter are saved, so that when the picture is opened again, the corresponding content can be displayed in the preview window directly according to the saved zooming parameter and the saved location information.
As directed to the problem that the volume of the information of the odd-shaped picture is large and hence the user may not read the full content in the odd-shaped picture in one time, a correspondence between the user's last browse location and the odd-shaped picture is established, and the zooming parameter for the odd-shaped picture is saved, so that when the user opens the odd-shaped picture again, it does not need to recalculate the zooming parameter for the odd-shaped picture, and the odd-shaped picture can be rapidly adjusted to a suitable size for the user to read; also, by jumping the current display location of the odd-shaped picture to the user's last browse location, it may be avoided that the user manually switches the content that has been read, thus improving the user reading experience.
