Abstract
A method for generating a signed distance field image, methods for processing a text effect, a device and a medium are provided. The method for generating a signed distance field image includes: determining a target closed curve in an unsigned distance field image of target text, drawing a target triangle; counting for pixels within the target triangle; determining that pixels having counting results equal to 0 in the unsigned distance field image are located in an interior region of the target text, and determining that pixels having counting results not equal to 0 in the unsigned distance field image are located in the exterior region; and generating a signed distance field image of the target text based on the pixels located in the exterior region, the pixels located in the interior region, and the unsigned distance field image.
