Picture format conversion method, device, apparatus, and storage medium

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. 本发明公开了种图片格式转换方法、装置、设备和存储介质，涉及图片处理技术领域，该方法包括：获取
