Some basic things i've tried to solve this issue:
很可能是 JPG 重命名为 PNG 文件,而不是实际的 PNG 文件问题可能是由于图像的错误扩展名造成的.就我而言,该文件是 JPEG 图像,但它保存为 PNG 未转换为.在这种情况下,将扩展名更改为真实的扩展名并转换为 PNG,然后重试.
It's likely a JPG renamed to a PNG file, not an actual PNG file The problem could be because of the wrong extension of images. In my case, the file was a JPEG image but it was saved as PNG not converted to. In this situation change extension to the real one and convert to PNG then retry.
例如,您有 ic_logo.png,但它实际上是 JPG 图片.您应该将其重命名为 ic_logo.jpg 并使用 Photoshop 之类的工具将图像转换为 PNG 格式.
For instance, you have ic_logo.png but it's actually a JPG image. You should rename it back to ic_logo.jpg and use something like Photoshop to convert the image to PNG format.
