Question

在此处输入图片说明

我是这个图像处理的新手。为什么我问这个问题是因为我有一个适用于RGB模式但不适用于P模式的代码？所以我得出的结论是它与模式有关。我做了一些关于模式的基础研究。但没有找到任何简单的解释。如果有人可以帮助我理解这一点，将会有所帮助。

代码：

image=Image.open('image.png')
image.load()

image_data = np.asarray(image)
image_data_bw = image_data.max(axis=2)
non_empty_columns = np.where(image_data_bw.max(axis=0)>0)[0]
non_empty_rows = np.where(image_data_bw.max(axis=1)>0)[0]
cropBox = (min(non_empty_rows), max(non_empty_rows), min(non_empty_columns), max(non_empty_columns))

image_data_new = image_data[cropBox[0]:cropBox[1]+1, cropBox[2]:cropBox[3]+1 , :]

new_image = Image.fromarray(image_data_new)
new_image.save('cropped_image.png')

Codesource

输入到图片后面的代码：

输出应如下图所示（裁剪到图片的边缘。请点击图片进行理解）：

此图像处于RGBA模式。因此代码适用于此类图像。但不是P模式下的图像。

错误： 我在P模式下遇到错误：轴2超出了维2的数组

Answer 1

您发现的答案通过使用numpy极大地使过程复杂化。 PIL库本身支持此用例，使用image.getbbox()和image.crop()方法：

cropbox = image.getbbox()
new_image = image.crop(cropbox)

这适用于所有不同的模式，无论如何。 image.getbbox()生成的庄稼大小与numpy路线生成的庄稼大小完全相同。

This code completely crops the image to the edges. Only if the images are having alpha channel, you might have to remove that channel by converting it.

ex. If it is a RGBA mode make it RGB and then use from PIL import Image img = Image.open('Image.png') print(x,y) img.show() cropbox_1 = img.getbbox() new_image_1 = img.crop(cropbox_1) new_image_1.save('Cropped_image,png') new_image_1.show().

getbbox()

addition of this should do the task.

有人可以解释我不同类型的图像模式吗？
