This article guides on how to put signature on photo using Python. It has all the details to set up the IDE, a list of steps, and a sample code demonstrating how to put signature on pictures using Python. You will customize the signature image in PNG format and paste it on the target image (PNG, JPEG, BMP, TIFF, GIF, etc.) at a specified location.

Steps to Insert Signature in JPG using Python

1. Establish the environment to use Aspose.Imaging for Python via .NET to put a signature on a photo
2. Load the main image and signature image with a white background into the RasterImage object
3. Optionally resize the signature image if you want to paste it in a limited space
4. Load the signature image into memory using the cache_data() method and access all its pixels with the load_argb_32_pixels() method
5. Iterate through all the pixels of the signature and set whitish pixels transparent by setting their alpha value to 0
6. Save the pixels back to the signature image after making its background transparent
7. Link the main image with the Graphics object and draw a transparent signature on it using the draw_image method

These steps summarize the process of how to put signature on a picture using Python. Load both the main image and the signature image into the Image class, typecast to RasterImage, load the signature image into memory, access its pixels, and iterate through all of the pixels to search for white pixels and make them transparent. Save the pixels back to the signature image, load the main image to the Graphics object and draw the transparent signature at a specified location on the main image.

Code to Put Your Signature on Your Photos using Python

The above code demonstrates how to put your signature on a photo using Python. In this picture, we have assumed that the signature background is white; therefore, we have searched for pixels with a value greater than 240. However, if your signature background is different, you may search for those pixels and make them transparent if required.
