将图片中的黄色修改为红色

from PIL import ImageDraw,Image
img = Image.open(r'C:Users87823Desktopwarning.jfif')
draw_obj = ImageDraw.Draw(img)
w,h = img.size
# 创建图像区域
img_output = Image.new('RGB',(2*w,h))
# 将原图复制到(0,0)
img_output.paste(img,(0,0))

def get_color():
    # 将黄色修改为红色
    # print(oldColor)
    # 获取每个通道的值 正宗的黄色(255,255,0)
    if oldColor[0]>60 and oldColor[1]>60:
        return(oldColor[0],0,oldColor[2]) # 返回红色
    else:
        return oldColor

for x in range(w):
    for y in range(h):
        oldColor = img.getpixel((x,y))
        draw_obj.point((x,y),fill=get_color())
img_output.paste(img,(w,0))
img_output.show()
