java thumbnail image program


I have some problem to make thumbnail" in JAVA.

Our web site have some function to upload image file.

When a user upload image file (jpg, jpeg, png, gif...), our system try to resize that image (size: 10 ~ 30Kb) and make thumbnail because big image cause big traffic.

Almost image seems to be good.

But i have two problems.

1) CMYK image cause big problem. program don't make thumbnail well because CMYK file is jpeg that a user make via Adobe photoshop and color table is different with general jpg.. i know.

2) quality is "low"

Our source is as follow.

1) BufferedImage originalImage = [url removed, login to view](loadFile);

int type = [url removed, login to view]() == 0? BufferedImage.TYPE_INT_ARGB : [url removed, login to view]();

BufferedImage resizeImageHintJpg = resizeImageWithHint(originalImage, type, 555, 370);

[url removed, login to view](resizeImageHintJpg, "jpg", saveFile);

2) private static BufferedImage resizeImageWithHint(BufferedImage originalImage, int type, int width, int height){

BufferedImage resizedImage = new BufferedImage(width, height, type);

//BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type);

Graphics2D g = [url removed, login to view]();

//[url removed, login to view](originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null);

[url removed, login to view](originalImage, 0, 0, width, height, null);

[url removed, login to view]();

[url removed, login to view]([url removed, login to view]);

[url removed, login to view](RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);

[url removed, login to view](RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);

[url removed, login to view](RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

return resizedImage;


Could you do that?
