------------------------------------
Summary: Wrong colors while reading JPEG and converting to BMP
Key: IMAGING-372
URL: https://issues.apache.org/jira/browse/IMAGING-372
Project: Commons Imaging
Issue Type: Bug
Components: imaging.*
Affects Versions: 1.0-alpha3
Environment: Tested with Java 1.8.0_281 on Windows 10 Professional
Reporter: Norman Geyer
Fix For: Patch Needed
Attachments: 25606_200x200.jpg, 25606_200x200.jpg.bmp, 91691-01.jpg,
91691-01.jpg.bmp
Hi. I am reading JPEG image file and using this library to convert it to BMP
format. Resultant bitmap file has wrong color comparing to original file. Below
is the code :
{code:java}
ArrayList<File> files = new ArrayList<File>();
files.add(new File("./files/25606_200x200.jpg"));
files.add(new File("./files/91691-01.jpg"));
for (File file : files)
{
try
{
//File trgFile = ImageConverter.convert(file, "bmp");
final BufferedImage bi = Imaging.getBufferedImage(file); final
File dstFile = new File(file .getAbsolutePath() + ".bmp");
Imaging.writeImage(bi, dstFile, ImageFormats.BMP);
System.out.println(dstFile.getName() + " has been converted successfully.");
}
catch (Exception e)
{
e.printStackTrace();
}
}{code}
Image "25606_200x200.jpg.bmp" has the wrong color depth, image
"91691-01.jpg.bmp" has the right color depth but wrong color mapping (maybe the
embedded ICC-Profile is the cause here).
