There have been similar issues reported in the past, and usually it can be solved by forcing the image type to be BufferedImage.TYPE_INT_ARGB
by .outputFormat(BufferedImage.TYPE_INT_ARGB)
-- not setting this will make Thumbnailator perform image processing on the original image type which could introduce these types of issues.

Perhaps .outputFormat(BufferedImage.TYPE_INT_ARGB) is a typo?
It was meant .imageType(BufferedImage.TYPE_INT_ARGB)?
int imgType = originalImage.getType();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Thumbnails.of(originalImage)
.size(targetWidth, targetHeight)
.outputFormat(formatName)
//.imageType(imgType)
.imageType(BufferedImage.TYPE_INT_ARGB)
.outputQuality(1)
.toOutputStream(outputStream);
Unfortunately, the above code did not help to fix the error.

I had a similar issue (converting from PNG
to JPG
) but fixed it by using BufferedImage.TYPE_INT_RGB
BufferedImage thumbnailImg = Thumbnails.of(pngImage)
.size(width, height)
.outputFormat("jpg")
.imageType(BufferedImage.TYPE_INT_RGB) // PNG -> JPG
.asBufferedImage();
It's a bit cumbersome since we need to set imageType(...)
manually
