Convert Png To Sdf Link

# 5. Calculate Euclidean Distance Transform # dt = Distance to nearest 0 (edge) dt = ndimage.distance_transform_edt(shape)

# 2. Normalize to binary (0 or 255) _, binary = cv2.threshold(img, 127, 255, cv2.THRESH_BINARY) convert png to sdf

# 4. Invert for distance calculation (Scipy treats '0' as foreground) # If your shape is white (1), invert it so shape is 0. shape = 1 - binary binary = cv2.threshold(img

Standard SDFs struggle with sharp corners (like the tip of a star). If you need perfect vector quality, look into MSDF (Multi-channel SDF). Converting PNG to MSDF requires specialized tools like msdfgen . The Result: Perfect Scaling Once converted, you can render your SDF in a shader like this (GLSL snippet): convert png to sdf
