Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

An embodiment of the present invention provides a method for processing a picture, and FIG. 1 is a flowchart of a method for processing a picture provided by an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

Step 110: Obtain processing information corresponding to the target picture, where the processing information includes thumbnail images and preset coefficients.

Specifically, the processing information may be, but is not limited to, information stored by the terminal itself, or may be information sent by other terminals. The target picture can be, but is not limited to, a picture of normal size and size that needs to be processed. Thumbnails can be, but are not limited to, pictures generated based on normal pictures and according to preset coefficients.

In one embodiment, as shown in FIG. 2 , the processing information corresponding to the target picture is obtained, and the processing information includes thumbnail images and preset coefficients before the steps include:

Step 210: obtain the target image;

Step 220: Keep the aspect ratio of the target picture unchanged, and generate a thumbnail corresponding to the target picture according to a preset coefficient.

Specifically, the acquisition target picture may be acquired from but not limited to the terminal itself, and may also be acquired from other terminals. Under the condition that the aspect ratio of the target picture is kept unchanged, a thumbnail image corresponding to the target picture is generated according to the preset coefficient. The preset coefficient may be, but not limited to, be set by the user, and may also be automatically generated according to the size of the terminal memory. The preset coefficient is a reference value for generating a thumbnail image corresponding to the target image, and the thumbnail image displayed in the operation area occupies a lower heap memory than the target image. The height and width of the thumbnail is equal to the height and width of the target image corresponding to the thumbnail/the preset coefficient. For example, as shown in FIG. 3 , the height and width of the normal picture 31 are H1 and W1 respectively, and after scaling according to the preset coefficient S, the height and width of the thumbnail 32 are H2 and W2 respectively.

In one embodiment, as shown in FIG. 4 , the processing information corresponding to the target picture is obtained, and the processing information includes thumbnail images and preset coefficients before the steps include:

Step 410: Detect whether its own heap memory usage is greater than a predetermined value;

Step 420: If the heap memory occupation is greater than the predetermined value, execute the step of acquiring processing information corresponding to the target picture, where the processing information includes thumbnail images and preset coefficients.

Specifically, the predetermined value may be, but is not limited to, zero, that is, as long as it is detected that its own heap memory is occupied, the step of obtaining processing information corresponding to the target picture, where the processing information includes thumbnail images and preset coefficients, is performed. The predetermined value can be set according to terminal conditions.

Step 120: In response to the operation instruction on the thumbnail, scale the first critical path corresponding to the operation instruction according to a preset coefficient, and generate a second critical path corresponding to the target image.

Specifically, in the process of displaying the thumbnail in the operation area, the user performs a picture processing operation on the thumbnail. The operation instruction may be, but not limited to, cropping, compositing, and rotating the thumbnails. In one embodiment, the operation instruction includes: performing a cropping operation on the thumbnails; and/or performing a synthesizing operation on the thumbnails; and/or performing a rotation operation on the thumbnails. Specifically, the first critical path corresponding to the operation instruction is calculated according to the preset coefficients to generate the second critical path for image processing on the target image. For example, as shown in FIG. 5 , if the height and width of the cropping or compositing area 51 determined by the first critical path for the thumbnail are H3 and W3, respectively, and the rotation angle A, the relative coordinates with respect to the vertex of the upper left corner of the thumbnail are (DX, DY), then according to the second critical path generated by the preset coefficients, the coordinates of the upper left corner vertex of the determined cropping or synthesizing region 52 relative to the target picture are (DX*S, DY*S), and the height and width are respectively H4=H3* S, W4=W3*S, and the rotation angle A is recorded. The rotation angle A may be, but is not limited to, equal to zero.

Step 130: Process the target picture according to the second critical path to obtain the processed target picture.

Specifically, after the above-mentioned second critical path is generated, the API corresponding to the bitmap or ffmpeg is called for processing, and the target image after image processing is generated. If it is a cropping operation, the target image after image processing is generated after the cropping area on the target image is determined, and the target image is rotated by the angle A; if it is a composite operation, the image that needs to be combined is scaled to determine the size of the composite area. And rotate the angle A, record the bitmap generated in this step as bm2, call the draw function, first draw the original image bm1, then draw bm2, and pass the function parameters into the coordinates of the upper left corner after playback. In one embodiment, the step of processing the target picture according to the second critical path to obtain the processed target picture includes: processing the target picture through an underlying library, so that heap memory is saved.

In a picture processing method provided by an embodiment of the present application, by acquiring processing information corresponding to a target picture, the processing information includes a thumbnail image and a preset coefficient, and in response to an operation instruction on the thumbnail image, scaling the image with the preset coefficient according to the preset coefficient The first critical path corresponding to the operation instruction, the second critical path corresponding to the target picture is generated, and the target picture is processed according to the second critical path to obtain the processed target picture, so that the terminal occupies the There is less heap memory, which saves the use of heap memory, improves the speed of interactive response, and effectively prevents OOM exceptions during image processing.
