[英]How can I get the actual color of the image while uploading to Bugzilla tool using java code with out any distortion?
**我正在使用下面的代碼從文件夾中獲取多個失敗截圖到 Bugzilla 工具,在 Bugzilla 中上傳圖片時,圖片顏色失真。 [在此處輸入圖像描述][1]。 誰能幫我糾正這個問題。 ? **
try {
BugzillaConnector conn = new BugzillaConnector();
conn.connectTo("bugzilla.com");
LogIn logIn = new LogIn("username", "password");
conn.executeMethod(logIn);
Bug bug = new BugFactory()
.newBug()
.setProduct("SeleniumFramework")
.setComponent("CoreJavaTestNG")
.setVersion("1.0").setPlatform("PC")
.setOperatingSystem("Windows")
.setDescription("Bug posted from Java Source Code")
.setSummary("Bug posted from Java Source Code")
.createBug();
ReportBug report = new ReportBug(bug);
conn.executeMethod(report);
int bugID = report.getID();
System.out.println("Bug posted and its ID is " + bugID);
GetBug get = new GetBug(bugID);
conn.executeMethod(get);
System.out.println(get.getBug().getID());
System.out.println(get.getBug().getSummary());
System.out.println(get.getBug().getProduct());
System.out.println(get.getBug().getComponent());
System.out.println(get.getBug().getVersion());
System.out.println(get.getBug().getPlatform());
System.out.println(get.getBug().getOperatingSystem());

ByteArrayOutputStream bos = new ByteArrayOutputStream();

}

您看到的粉紅色/淡紅色是因為源圖像包含 Alpha 通道。
ImageIO
中有一個已知錯誤,它會將 alpha 通道包含到 JPEG 圖像的 output 中(或者類似的東西,如果你真的感興趣,可以用谷歌搜索)。
您的問題的基本解決方案是使用TYPE_INT_RGB
將原始圖像應用於BufferedImage
,這將刪除 alpha 通道,例如,請參閱刪除 PNG BufferedImage 中的透明度。
我使用了代碼,但在圖像上得到了藍色背景
所以,從這個透明的PNG開始
並使用下面的代碼......
BufferedImage original = ImageIO.read(new File("/Users/shanew/Downloads/transparent.png"));
BufferedImage copy = new BufferedImage(original.getWidth(), original.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics2D g2d = copy.createGraphics();
g2d.setColor(Color.WHITE); // Or what ever fill color you want...
g2d.fillRect(0, 0, copy.getWidth(), copy.getHeight());
g2d.drawImage(original, 0, 0, null);
g2d.dispose();
File dest = new File("Test.jpg");
ImageIO.write(copy, "jpg", dest);
BufferedImage test = ImageIO.read(dest);
JPanel panel = new JPanel();
panel.add(new JLabel(new ImageIcon(original)));
panel.add(new JLabel(new ImageIcon(test)));
JOptionPane.showMessageDialog(null, panel);
我可以生產...
如果您仍然遇到問題,那么您需要做兩件事:
繼續在評論中發布代碼沒有幫助
