How do I reduce the size of a photo in Pygame?

pygame. transform. scale() and pygame. transform….

1. Creates a new surface ( newSurface ) with size (width, height) .
2. Scale and copy Surface to newSurface .
3. Return newSurface .

How to rotate an image in Pygame without losing quality or?

When you’re rotating the image using pygame.transform.rotate(), pygame creates a new Surface with your rotated image on. By doing this your image lose some information and therefore some quality. That’s why it’s always practical to rotate the original image and not a rotated copy. In code it’ll look something like this:

How to transform an image into a Pygame transform?

pygame.transform.rotate()¶ rotate an image rotate(Surface, angle) -> Surface Unfiltered counterclockwise rotation. The angle argument represents degrees and can be any floating point value. Negative angle amounts will rotate clockwise. Unless rotating by 90 degree increments, the image will be padded larger to hold the new size.

How to rotate an image around its center using Python?

Rotate the vectors to the corner points by pygame.math.Vector2.rotate: Get the minimum and the maximum of the rotated points: Calculate the “compensated” origin of the upper left point of the image by adding the minimum of the rotated box to the position.

What are the dimensions of the surface in Pygame?

This prevents angle to overflow. Surfaces in pygame can’t actually be rotated; they have a horizontal width and a vertical height. When you load your image pygame creates a Surface which has a horizontal width and a vertical height equal to your image.
