对于相册播放器,大家应该都不生疏 (用于浏览多张图片的一个利用)。
当然还有视频、音乐播放器,同样是用来播放多个视频、音乐文件的。
在 Win10 零碎下,用【 照片 】这个利用关上一张图片,就能够浏览该图片所在文件夹中其它图片了。
从下面的图中发现,还有不少其它方面的性能,比方图片裁剪、编辑、打印等。
明天就带大家学习一个 Python 制作相册播放器的实战我的项目。
性能嘛,当然没有零碎自带的好,仅做学习哈。
默认 5 秒切换一张图片,点击向前按钮,能够疾速切换到下一张图片。
次要应用到 Pygame 这个库,创立一个图形界面。
还有 Tkinter 库,因为要增加一个图片文件夹,应用 tkinter 的 filedialog 疾速选取本地文件夹。
# 装置
pip install pygame
pip install tkinter
好了,接下来就给大家介绍一下。
导入相干库。
import os
import sys
import glob
import pygame
import tkinter
import os.path
from button import Button
from tkinter import filedialog
初始化,设置图形界面的宽为 1600,高为 900。
增加标题栏图表和标题栏文字,以及中文字体,这里用宋体,所以界面显得有些丑 …
最初设置文字背景色和背景图片。
# 初始化
pygame.init()
# 设置宽, 高, 标题栏
WIDTH, HEIGHT = 1600, 900
SCREEN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("相册播放器 | 小 F 2022")
# 增加中文字体
def bold_font(size):
os.chdir(sys.path[0])
return pygame.font.Font("assets/simhei.ttf", size)
def regular_font(size):
return pygame.font.SysFont("simhei", size)
# 设置文字背景色, 背景图片
BASE_TEXT_COLOR = "#6fffe9"
BACKGROUND_IMAGE = pygame.image.load("assets/background.png")
SCREEN.blit(BACKGROUND_IMAGE, (0, 0))
# 更新
pygame.display.update()
# 设置标题栏图标
WINDOW_ICON = pygame.image.load("assets/window_icon.png")
pygame.display.set_icon(WINDOW_ICON)
成果如下,空空荡荡。
加载局部按钮的图标。
# 设置按钮背景色, 向后按钮, 暂停按钮, 播放按钮, 向前按钮, 加载新相册按钮
MAIN_MENU_BUTTON_BACKGROUND = pygame.image.load("assets/main_menu_button_bg.png")
REWIND_ICON_SURFACE = pygame.image.load("assets/rewind_icon.png")
PAUSE_ICON_SURFACE = pygame.image.load("assets/pause_icon.png")
PLAY_ICON_SURFACE = pygame.image.load("assets/play_icon.png")
SEEK_ICON_SURFACE = pygame.image.load("assets/seek_icon.png")
LOAD_NEW_ALBUM_SURFACE = pygame.image.load("assets/load_new_album_icon.png")
设置按钮背景色,向后按钮,暂停按钮,播放按钮,向前按钮,加载新相册按钮。
其次定义各个按钮的性能函数。
# 加载按钮函数
def load_button():
# 关上文件管理器, 抉择文件夹
filedialogwindow = tkinter.Tk()
filedialogwindow.withdraw()
filepath = filedialog.askdirectory(title="抉择你的相册")
filedialogwindow.destroy()
album_player(filepath)
# 敞开按钮
def quit_button():
pygame.quit()
sys.exit()
# 向后按钮
def rewind_button(current_image_index):
if current_image_index > 0:
current_image_index -= 1
rewind_button_pressed = True
return rewind_button_pressed, current_image_index
# 向前按钮
def seek_button(current_image_index, image_names):
if current_image_index+1 < len(image_names):
current_image_index += 1
seek_button_pressed = True
return seek_button_pressed, current_image_index
# 播放按钮
def play_button():
paused = False
unpaused = True
return paused, unpaused
# 暂停按钮
def pause_button():
paused = True
unpaused = False
return paused, unpaused
加载按钮,增加相册;
敞开按钮,退出播放器;
向后按钮,向后切换一张图片;
向前按钮,向前切换一张图片;
播放按钮,开始播放相册中的图片;
暂停按钮,暂停相册图片的播放;
设置主界面,蕴含主页标题栏,加载按钮,敞开按钮文字属性。
同时还须要监听鼠标点击事件。
# 主界面
def main_menu():
# 主页标题栏
TITLE_TEXT_SURFACE = bold_font(120).render("相册播放器", True, BASE_TEXT_COLOR)
TITLE_TEXT_RECT = TITLE_TEXT_SURFACE.get_rect(center=(WIDTH/2, 175))
SCREEN.blit(TITLE_TEXT_SURFACE, TITLE_TEXT_RECT)
# 加载按钮
LOAD_BUTTON = Button(surface=MAIN_MENU_BUTTON_BACKGROUND, pos=(WIDTH/2, 415), text_input="加载",
font=bold_font(100), base_color=BASE_TEXT_COLOR, hovering_color="white"
)
# 敞开按钮
QUIT_BUTTON = Button(surface=MAIN_MENU_BUTTON_BACKGROUND, pos=(WIDTH/2, 585), text_input="敞开",
font=bold_font(100), base_color=BASE_TEXT_COLOR, hovering_color="white"
)
while True:
# 监听鼠标点击事件
current_mouse_pos = pygame.mouse.get_pos()
LOAD_BUTTON.update(SCREEN)
QUIT_BUTTON.update(SCREEN)
# 依据鼠标点击状况, 是否点击右上角的敞开
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# 依据鼠标点击状况, 点击加载或敞开按钮
if event.type == pygame.MOUSEBUTTONDOWN:
if LOAD_BUTTON.check_for_input(current_mouse_pos):
load_button()
if QUIT_BUTTON.check_for_input(current_mouse_pos):
quit_button()
# 当鼠标搁置在按钮上, 按钮色彩产生扭转
LOAD_BUTTON.change_color(current_mouse_pos)
QUIT_BUTTON.change_color(current_mouse_pos)
pygame.display.update()
依据鼠标点击状况, 是否点击右上角的敞开;
依据鼠标点击状况, 点击加载或敞开按钮;
当鼠标搁置在按钮上, 按钮色彩产生扭转,变成红色。点击敞开,利用会敞开掉。
最初是相册播放器的性能函数,设置每 5s 切换一张图片。
此外还要调整图片的尺寸大小,不便在播放器中查看。
# 相册播放器性能函数
def album_player(folder_path):
SCREEN.blit(BACKGROUND_IMAGE, (0, 0))
image_file_paths = []
image_names = []
current_image_index = 0
paused = False
unpaused = False
seek_button_pressed = False
rewind_button_pressed = False
# 增加加载按钮后, 失去的图片文件夹门路
os.chdir(folder_path)
for file in glob.glob("*"):
current_image_path = f"{folder_path}/{file}"
# 图片门路列表
image_file_paths.append(current_image_path)
# 图片名称列表
image_names.append(file)
# 向后按钮
REWIND_BUTTON = Button(surface=REWIND_ICON_SURFACE, pos=(WIDTH/2-100, HEIGHT-150), text_input="",
font=bold_font(100), base_color=BASE_TEXT_COLOR, hovering_color="white"
)
# 暂停按钮
PAUSE_BUTTON = Button(surface=PAUSE_ICON_SURFACE, pos=(WIDTH/2, HEIGHT-150), text_input="",
font=bold_font(100), base_color=BASE_TEXT_COLOR, hovering_color="white"
)
# 播放按钮
PLAY_BUTTON = Button(surface=PLAY_ICON_SURFACE, pos=(WIDTH/2, HEIGHT-150), text_input="",

)

)
# 加载新相册按钮

font=bold_font(100), base_color=BASE_TEXT_COLOR, hovering_color="white"
)
# 获取工夫, 设置每 5s 切换一张图片
previous_time = pygame.time.get_ticks()
COOLDOWN = 5000
# 设置图片名称文字属性
photo_title_text_surface = bold_font(90).render(image_names[current_image_index], True, BASE_TEXT_COLOR)
photo_title_text_rect = photo_title_text_surface.get_rect(center=(WIDTH/2, 150))
# 图片张图显示
image_count_text_surface = regular_font(80).render(f"图片 {current_image_index+1}/{len(image_names)}", True, BASE_TEXT_COLOR)
image_count_text_rect = image_count_text_surface.get_rect(center=(300, 755))
# 获取图片宽高属性, 窗口显示不适合, 调整大小
new_image_surface = pygame.image.load(image_file_paths[current_image_index])
if new_image_surface.get_height() > 500:
new_image_surface = pygame.transform.scale(new_image_surface, (new_image_surface.get_width() * (500/new_image_surface.get_height()), 500))
elif new_image_surface.get_width() > 800:
new_image_surface = pygame.transform.scale(new_image_surface, (800, new_image_surface.get_height() * (800/new_image_surface.get_width())))
new_image_rect = new_image_surface.get_rect(center=(WIDTH/2, HEIGHT/2))
SCREEN.blit(new_image_surface, new_image_rect)
SCREEN.blit(photo_title_text_surface, photo_title_text_rect)

# 切换图片, 肯定工夫、点击向后按钮、点击向前按钮、点击开始按钮
if current_time - previous_time >= COOLDOWN or rewind_button_pressed or seek_button_pressed or paused or unpaused:
unpaused = False
if current_image_index < len(image_file_paths)-1 and not seek_button_pressed and not rewind_button_pressed and not paused:
current_image_index += 1
SCREEN.blit(BACKGROUND_IMAGE, (0, 0))
REWIND_BUTTON.update(SCREEN)

SEEK_BUTTON.update(SCREEN)
LOAD_NEW_ALBUM_BUTTON.update(SCREEN)
new_image_surface = pygame.image.load(image_file_paths[current_image_index])
if new_image_surface.get_height() > 500:
new_image_surface = pygame.transform.scale(new_image_surface, (new_image_surface.get_width() * (500/new_image_surface.get_height()), 500))

SCREEN.blit(image_count_text_surface, image_count_text_rect)

同样也有监听鼠标点击事件,依据鼠标点击状况,做向前、向后、暂停、开始等切换图片操作。
最终成果如下。
好了,本期的分享就到此结束了,有趣味的小伙伴能够自行去实际学习。
