Document Type and Number:
WIPO Patent Application WO/2022/161238
Kind Code:
A1
Abstract:
Provided are a signed distance field image generation method, a text effect image generation method, a device and a medium. The signed distance field image generation method comprises: on the basis of a drawing direction of a triangle, counting pixel points in a triangle area; and determining that pixel points with a counting result of 0 are in an exterior area of target text, and determining that pixel points with a counting result of not 0 are in an interior area of the target text, thereby more accurately determining the positions of pixel points in an overlapping area of a closed area in the target text. It can be seen that in the embodiments of the present disclosure, by means of changing the manner of counting pixel points in a shape drawing stage, and determining the manner of determining, on the basis a counting result, whether the pixel points are in an interior area of target text, the accuracy of determining whether pixel points in overlapping area of a closed curve in target text is in an interior area of the target text is improved, thereby improving the accuracy of generating a signed distance field image. In addition, by means of the text effect image generation method provided in the embodiments of the present disclosure, a text effect image can be generated on the basis of a signed distance field image.
