sun.awt.image.ImageFormatException: Unsupported color conver

#28366

It could be that your jpeg is using the CMYK color model rather than RGB.

You can convert it on a fly (with JAI, for example) using custom resource loaders API.

#28367

Hi,

I tried the CMYK to RGB conversion trick (CmykImageLoader.java) but my image can’t get metadata with reader.getImageMetadata(0);. Is there any others way for me to solve sun.awt.image.ImageFormatException: Unsupported color conversion request?

...
if ("JPEG".equalsIgnoreCase(format) || "JPG".equalsIgnoreCase(format)) {

IIOMetadata metadata = reader.getImageMetadata(0);

String metadataFormat = metadata.getNativeMetadataFormatName();
IIOMetadataNode iioNode = (IIOMetadataNode) metadata.getAsTree(metadataFormat);
...

What kind of error it produces?

reader.getImageMetadata is null so unable to proceed to next line of code.

Any idea on this issue? I don’t know why I can’t get any information from Image Metadata.
