我正在尝试调整图像大小以在我的OLED设备上显示。
根据How to resize image?,我在脚本中添加了new_img = img.resize((128,128))
来调整图片大小。然而,图像的相同部分出现在屏幕上。当我尝试为resize参数(64x64)输入较小的图像大小时,终端打印:
pi@raspberrypi:~/project $ python colors.py --display ssd1351 --width 128 --height 128 --interface spi --spi-bus-speed 16000000 --gpio-data-command 20
Version: luma.oled 2.3.1 (luma.core 1.3.0)
Display: ssd1351
Interface: spi
Dimensions: 128 x 128
------------------------------------------------------------
Traceback (most recent call last):
File "colors.py", line 87, in <module>
main()
File "colors.py", line 30, in main
device.display(new_img)
File "/usr/local/lib/python2.7/dist-packages/luma/oled/device.py", line 371, in display
assert(image.size == self.size)
AssertionError
关于如何为OLED显示器正确调整图像大小的任何想法?
我的完整脚本是:
#!/usr/bin/env python
import math
import time
import random
import os.path
from demo_opts import get_device
from luma.core.render import canvas
from PIL import Image
def main():
img_path = os.path.abspath(os.path.join(
os.path.dirname(__file__), 'plot.jpg'))
img = Image.open(img_path) \
.transform(device.size, Image.AFFINE, (1, 0, 0, 0, 1, 0), Image.BILINEAR) \
.convert(device.mode)
new_img = img.resize((128,128))
while True:
# Image display
device.display(new_img)
time.sleep(5)
if __name__ == "__main__":
try:
device = get_device()
main()
except KeyboardInterrupt:
pass
答案 0 :(得分:1)
好的,我通过以下方式解决了这个问题:
img = Image.open(img_path)
img = img.resize((128, 128), Image.ANTIALIAS) \
.transform(device.size, Image.AFFINE, (1, 0, 0, 0, 1, 0), Image.BILINEAR) \
.convert(device.mode)
在运行转换和转换之前,首先调整图像大小。
