Python PIL 裁剪时进程意外退出
Python PIL unexpected quit of process when cropping
我正在编写一个简短的脚本，它将 tiff 文件分成更小的部分。
文件比一般大（最大文件有 16000 x 28800 像素 1 位深度）
我的想法是，裁剪每个矩形并将其另存为新文件，分辨率与原始图像相同
from PIL import Image
Image.MAX_IMAGE_PIXELS = None
rows = 9
cols = 5
im = Image.open("Patches_TP_2540.tif")
width, heigth = im.size
res = 2540
print(width, heigth)
patchSize = int(width / cols)
offset_x_tl = 0
offset_y_tl = 0
for r in range(rows):
offset_y_tl = r * patchSize
for c in range(cols):
print(r, c)
offset_x_tl = c * patchSize
offset_y_br = offset_y_tl + patchSize
offset_x_br = offset_x_tl + patchSize
print(offset_x_tl, offset_y_tl, offset_x_br, offset_y_br)
croped_area = im.crop((offset_x_tl, offset_y_tl, offset_x_br, offset_y_br))
croped_area.save("Patch_"+ str(res) +"_" + str(r) + "_" + str(c) +".tiff", dpi=(2540,2540))
print("Done!")
如果我 运行 这段代码结束时不会打印完成！如果我删除 croped_area 和保存命令，代码是 运行ning 没问题。创建一个新图像并保存它也可以。
我还尝试使用带有 im.copy() 的临时图像。如果我这样做，代码会在复制过程中停止。
也许有人可以帮我解决这个问题，并提供一些解决问题的技巧。

它接缝 PIL 并且作物在 LZW 压缩方面存在一些问题。
使用 Photoshop 删除压缩后脚本 运行 符合预期。
如果您有边界框区域的想法可以使用这种方法裁剪图像
from PIL import Image
img = Image.open("imagefile")
#例如
的边界区域
#left = 90, top = 580, right = 1600, bottom = 2000
img_res = img.crop((left, top, right, bottom))
with open(outfile4, 'w') as f:
img_res.save(outfile_path,'JPEG')
我正在编写一个简短的脚本，它将 tiff 文件分成更小的部分。
文件比一般大（最大文件有 16000 x 28800 像素 1 位深度）
我的想法是，裁剪每个矩形并将其另存为新文件，分辨率与原始图像相同
from PIL import Image
Image.MAX_IMAGE_PIXELS = None
rows = 9
cols = 5
im = Image.open("Patches_TP_2540.tif")
width, heigth = im.size
res = 2540
print(width, heigth)
patchSize = int(width / cols)
offset_x_tl = 0
offset_y_tl = 0
for r in range(rows):
offset_y_tl = r * patchSize
for c in range(cols):
print(r, c)
offset_x_tl = c * patchSize
offset_y_br = offset_y_tl + patchSize
offset_x_br = offset_x_tl + patchSize
print(offset_x_tl, offset_y_tl, offset_x_br, offset_y_br)
croped_area = im.crop((offset_x_tl, offset_y_tl, offset_x_br, offset_y_br))
croped_area.save("Patch_"+ str(res) +"_" + str(r) + "_" + str(c) +".tiff", dpi=(2540,2540))
print("Done!")
