Upscale an SVG image in python without losing its quality-CodePudding

I have an image in svg format of height and width 45 i want to upscale it to 75 is it possible to do without losing quality in pygame.

The image before resizing:

The image after resizing:

The code I used to resize:

pygame.transform.scale(pygame.image.load('bP.svg'),(75,75))

CodePudding user response：

this should help with upscaling as it uses a bilinear filter:

pygame.transform.smoothscale(pygame.image.load('bP.svg'),(75,75))

CodePudding user response：

The format of the Scalable Vector Graphics is a text format. You can edit the SVG file and add a global scale (see SVG/Transformationen). e.g.:

<svg
    transform="scale(2)"
    ...
>

Since 2.0.2, SDL Image supports SVG files (see SDL_image 2.0). Therefore with pygame version 2.0.1, pygame.image.load() supports SVG files.
The scaling must be done when the Scalable Vector Graphic is rendered in a pygame.Surface. It would be nice to have a scale or size argument in pygame.image.load(). However, something like this is not documented (yet).
