Problems solved by technology

However, the inventor found in practice that due to the limitations of the drawing software itself, after importing pictures in common formats, such as pictures in formats such as JPG, GIF, TIF, BMP, and PDF, although it is convenient for users to view them in various environments, the The content of the picture cannot be edited, and the user must complete the sketch of the outline one stroke at a time based on the imported picture, which makes the sketching process too cumbersome for the user

Embodiment 2

[0092] Figure 4 It is a flowchart of a picture format conversion method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the first embodiment above. refer to Figure 4 The method for image format conversion provided in this embodiment specifically includes the following steps:

[0093] S201. Obtain an optimal threshold of the bitmap image by using the Otsu algorithm.

[0094] For obtaining the optimal threshold of the bitmap image using the Otsu algorithm, reference may be made to the relevant description of S110 in the embodiment, and details are not repeated here.

[0095] S202. Acquire thresholds of all pixels in the bitmap image.

[0096]Specifically, because the optimal threshold is calculated based on the thresholds of all pixels, because when the optimal threshold is obtained, the thresholds of each pixel have already been determined. In this step, it is only necessary to obtain the recorded threshold. Optionally, whe...

Abstract

The invention discloses a picture format conversion method, a device, an apparatus and a storage medium, which relate to the technical field of picture processing. The method comprises steps: converting the bitmap picture into a binary picture according to the optimal threshold; a contour point of each colored area in the binary picture being searched to generate an editable graph, and the editable graph being determined according to the contour point. The method can solve the problem that after pictures are imported into drawing software in the prior art, the picture is non-editable, and realizes the generation of editable vector format picture based on the non-editable bitmap format picture, and the vector format picture can be considered as the sketch of the bitmap picture, that is, thesketch picture is completed quickly, at the same time, it is convenient for the user to carry on the secondary operation to the picture, thereby improving the user's experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of picture processing, and in particular, to a picture format conversion method, device, device, and storage medium. Background technique [0002] When using drawing software, users often need to sketch pictures in the software, such as cartoon characters. In order to ensure the accuracy of the sketch, the user usually imports a picture for sketch reference into the software, and then sketches. However, the inventor found in practice that due to the limitations of the drawing software itself, after importing pictures in common formats, such as pictures in formats such as JPG, GIF, TIF, BMP, and PDF, although it is convenient for users to view them in various environments, the The content of the picture cannot be edited, and the user must complete the sketch of the outline stroke by stroke based on the imported picture, which makes the sketch process too cumbersome for the user.
