now the problem I have is that the download.jpg is 4k res and if I try to fit that image in my window the img is very blurry and i have also tried many more img but they were all blurry
do I try to get a picture of the window size or do i have to do something else pls tell me....
You can't. You can choose between a blurred image with pygame.transform.smoothscale
bgimg = pygame.transform.smoothscale(bgimg, size)
or a jagged image with pygame.transform.scale
bgimg = pygame.transform.scale(bgimg, size)
If you don't want that, you have to use a higher resolution image.

I do run my code, but its suddenly gone, and I get this error saying "screen.fill(background_img)TypeError: invalid color argument"enter image description here.
I dont also know how to resize the background image that i want to use for my screen background
pygame.init()
background_img = pygame.image.load("C:\\Users\\lenovo\\Pictures\\maxresdefault.jpg")
(width, height) = (800, 800)
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('Hop Along')
screen.fill(background_img)
pygame.display.update()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.quit()
You cannot fill the display with an image. You must blit an image:
screen.fill(background_img)
screen.blit(background_img, (0, 0))
If the background image is a different size than the window, you can use pygame.transform.smoothscale to scale the image:
background_img = pygame.image.load("C:\\Users\\lenovo\\Pictures\\maxresdefault.jpg")
scaled_background = pygame.transform.smoothscale(background_img, (width, height))
screen.blit(scaled_background, (0, 0))
I'm trying to make a game using pygame but I came up with an issue of people getting annoyed of the resolution they're working with, and can't resize window without stretching it.
Here is an example picture of what I'm trying to achieve.
here's what I tried.
window.blit(pg.transform.scale(screen, (window.get_size())), (0, 0)) # The game screen stretching
PS: It's hard to explain so I had to show an image
Use the following algortihm:
Get the bounding rectangle of the image and set the center of the rectangle to the center of the destination rectangle.
Use pygame.Rect.fit() to resize and move the aspect ratio rectangle into the destination rectangle.
Use the size of the new rectangle to scale the image.
blit the image at the position of the rectangle.
def blit_fit(dest_surf, image, dest_rect):
image_rect = image.get_rect(center = dest_rect.center)
fit_rect = image_rect.fit(dest_rect)
scaled_image = pygame.transform.scale(image, fit_rect.size)
dest_surf.blit(scaled_image, fit_rect)
Minimal example:
import pygame
pygame.init()
window = pygame.display.set_mode((300, 300))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
image = font.render("Screen", True, (255, 255, 0))
pygame.draw.rect(image, (255, 255, 255), image.get_rect(), 1)
def blit_fit(dest_surf, image, dest_rect):
image_rect = image.get_rect(center = dest_rect.center)
fit_rect = image_rect.fit(dest_rect)
scaled_image = pygame.transform.scale(image, fit_rect.size)
dest_surf.blit(scaled_image, fit_rect)
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
window.fill(0)
blit_fit(window, image, window.get_rect())
pygame.display.flip()
clock.tick(100)
pygame.quit()
exit()
I'm making a game in Python using Pygame that includes a small avatar maker before the game starts, but instead of creating a big sprite sheet with 88 different combinations of hairstyles and colours, is there a way that I can just use a generic .png image of each hairstyle and apply colour to it in-game?
The hairstyles are saved as .png images with alpha and anti-aliasing, so they are not just one shade of colour. I've got 8 different hairstyles and 11 different colours. It wouldn't be a problem to load them in as a sprite sheet and clip them in-game, but if there was a way to apply colour (or hue) in the game then not only would it be easier on the memory, but would open it up to more possibilities.
If the image is a "mask" image, with a transparent background and a white (255, 255, 255) mask, then you can "tint" the image with ease.
Load the image:
image = pygame.image.load(imageName)
Generate a uniform colored image with an alpha channel and the same size:
colorImage = pygame.Surface(image.get_size()).convert_alpha()
colorImage.fill(color)
Blend the image with maskImage, by using the filter BLEND_RGBA_MULT:
image.blit(colorImage, (0,0), special_flags = pygame.BLEND_RGBA_MULT)
A sprite class may look like this:
class MySprite(pygame.sprite.Sprite):
def __init__(self, imageName, color):
super().__init__()
self.image = pygame.image.load(imageName)
self.rect = self.image.get_rect()
colorImage = pygame.Surface(self.image.get_size()).convert_alpha()
colorImage.fill(color)
self.image.blit(colorImage, (0,0), special_flags = pygame.BLEND_RGBA_MULT)
Minimal example: repl.it/#Rabbid76/PyGame-ChangeColorOfSurfaceArea-4
import pygame
def changColor(image, color):
colouredImage = pygame.Surface(image.get_size())
colouredImage.fill(color)
finalImage = image.copy()
finalImage.blit(colouredImage, (0, 0), special_flags = pygame.BLEND_MULT)
return finalImage
pygame.init()
window = pygame.display.set_mode((300, 160))
image = pygame.image.load('CarWhiteDragon256.png').convert_alpha()
hue = 0
clock = pygame.time.Clock()
nextColorTime = 0
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
color = pygame.Color(0)
color.hsla = (hue, 100, 50, 100)
hue = hue + 1 if hue < 360 else 0
color_image = changColor(image, color)
window.fill((96, 96, 64))
window.blit(color_image, color_image.get_rect(center = window.get_rect().center))
pygame.display.flip()
pygame.quit()
exit()

I'm having trouble with the framerate in my game. I've set it to 60 but it only goes to ~25fps. This was not an issue before displaying the background (was fine with only win.fill(WHITE)). Here is enough of the code to reproduce:
import os, pygame
os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (50, 50)
pygame.init()
bg = pygame.image.load('images/bg.jpg')
FPS = pygame.time.Clock()
fps = 60
WHITE = (255, 255, 255)
BLUE = (0, 0, 255)
winW = 1227
winH = 700
win = pygame.display.set_mode((winW, winH))
win.fill(WHITE)
pygame.display.set_icon(win)
def redraw_window():
#win.fill(WHITE)
win.blit(bg, (0, 0))
win.blit(text_to_screen('FPS: {}'.format(FPS.get_fps()), BLUE), (25, 50))
pygame.display.update()
def text_to_screen(txt, col):
font = pygame.font.SysFont('Comic Sans MS', 25, True)
text = font.render(str(txt), True, col)
return text
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
redraw_window()
FPS.tick(fps)
pygame.quit()
Ensure that the background Surface has the same format as the display Surface. Use convert() to create a Surface that has the same pixel format. That should improve the performance, when the background is blit to the display, because the formats are compatible and blit do not have to do an implicit transformation.
bg = pygame.image.load('images/bg.jpg').convert()
Furthermore, it is sufficient to create the font once, rather than every time when a text is drawn. Move font = pygame.font.SysFont('Comic Sans MS', 25, True) to the begin of the application (somewhere after pygame.init() and before the main application loop)
Instead use screen.blit(pygame.image.load(picture.png))
Just image = pygame.image.load(picture.png) then screen.blit(image)
( if you keep loading your pictures continuously it will get lag )
