Herewell commented 2 years ago

hi, I found a problem as follows: When I use the code below to compress the image，The compressed image is abnormal。

        Thumbnails.of(file)
                .size(640, 640)
                .keepAspectRatio(false)
                .toFile(resizeFile);

You can find the images before and after compression in the attachment。 How should i solve this problem，please help me

Environment JDK1.8 and thumbnailator's version is 0.4.8 after： after before: before

This is a problem with Java's default JPEG reader not reading the JPEG properly.

You'll likely get better results if you use TwelveMonkey ImageIO's JPEG reader instead; you'll just need to include it as a Maven dependency and as long as it's in the classpath, that JPEG reader will be used instead of the default JPEG reader.
