Embodiment Construction

[0018] The invention discloses a method for generating pictures based on mobile operating system picture editing, which includes the following steps:

[0019] Step 1. Load the preview image obtained by shrinking the high-definition image, and deliver it to the foreground renderer in the editing view for rendering, so as to display it to the user.

[0020] The width of the high-definition image is recorded as imgWidth, and the height is recorded as imgHeight; the width of the editing view is recorded as viewWidth, and the height is recorded as viewHeight; the zoom ratio of the preview image is recorded as scale, the width is recorded as width, and the height is recorded as height. The zoom ratio, width and height calculation formulas of the preview image are as follows:

[0021] scale = min(viewWidth / imgWidth, viewHeight / imgHeight)

[0022] width = scale * imgWidth

[0023] height = scale * imgHeight

[0024] Step 2. Edit the editing view through the editor in an interac...

Abstract

The invention relates to a picture generation method based on picture editing of a mobile operating system. Editing and generation of a high-definition picture of a mobile terminal are achieved through foreground and background separated rendering. The method comprises the following steps: firstly, loading a preview obtained by reducing an original high-definition image, and submitting the previewto an editing view for rendering; the user edits the rendered preview to generate edit element information, and the edit elements are rendered according to the equal-ratio reduced size, so that the effect of saving the running memory during editing is achieved; when the picture is generated, the original picture of the high-definition picture is rendered at the background, and then rendering is performed according to the original size of the editing element so as to generate the high-definition picture.

Description

technical field [0001] The invention relates to the field of picture processing based on a mobile operating system, in particular to a picture generation method based on picture editing of a mobile operating system. Background technique [0002] With the popularization of mobile terminals and the enrichment of their functions, users spend more and more time immersed in mobile terminals every day. Users can complete various operations through mobile terminals, such as taking pictures and editing pictures. [0003] In the prior art, when a user edits a picture, the picture editing program in the mobile operating system will take a screenshot of the editing view to generate and save the picture, which is more convenient and what you see is what you get. However, limited by the size of the editing view, the image generated after editing is the same size as the editing view, and high-resolution images cannot be generated. [0004] In view of this, the inventor of the present inv...
