Currently as per what I know the max resolution that can be created using pillow's image function is 3000*3000 but I need to create image which has resolution of 10000*10000 or more programmatically ???
If you people didn't get what I meant ,just comment to me rahter than closing this question (please)I will give a more detailed question!!!
The only ways to create a pixel-perfect SVG from a bitmap is to <rect/> elements for each pixel (or block of same-colored pixels), or to use an <image> element to reference your bitmap. In neither case will you end up reducing the file size.
A vector format like SVG is not well-suited to representing hand-tweaked pixels. You likely want to use a bitmap format that supports lossless compression, such as PNG. If file size is of critical importance, you may wish to use a tool like OptiPNG to ensure that your PNG files are as small as possible.
