: If you need to keep the image editable in design software, a PNG to PSD (Photoshop) conversion is best, which can be done via CloudConvert CloudConvert For 3D Modeling

| Offset | Type | Field | |--------|---------------|------------------| | 0 | uint32 magic | 0x50324400 ("P2D\0") | | 4 | uint16 width | pixels | | 6 | uint16 height | pixels | | 8 | uint8 bpp | bits per pixel (16, 24, 32) | | 9 | uint8 flags | 1=has alpha, 2=mipmaps | | 10 | uint32 data_offset | start of raw pixels | | 14 | byte[] ... | raw pixel data (RGB565 or RGBA8888) |

If existing tools do not fit your workflow, you can write a custom converter in under 150 lines of Python. Below is a simplified example using Pillow and opencv-python .

# Simplify polygon epsilon = tolerance * cv2.arcLength(contours[0], True) simplified = cv2.approxPolyDP(contours[0], epsilon, True)
