Question

我这里有一个非常有趣的问题。虽然使用圆形面膜，它工作得很好，但我发现我的设备有问题。所以我检查了模拟器（iOS 6），发现如果我使用尺寸为480 * 480或485 * 485的图像，则会出现“蒙版和图像尺寸不匹配”错误。我将尺寸改为470 * 470和500 * 500，效果很好。此外480 * 475也可以正常工作。具有特定尺寸的方形img给出错误，例如：694 * 694,690 * 690给出错误。模拟器的显示宽度在输出中显示750。

System.out.println("width " + Display.getInstance().getDisplayWidth()); //output = 750
if (profile_img != null && !"".equals(profile_img)) {
    Image roundMask = Image.createImage(placeholderForProfile.getWidth(), placeholderForProfile.getHeight(), 0xff000000);
    roundMask = roundMask.scaledWidth(screenWidth / 3);
    Graphics gr = roundMask.getGraphics();
    gr.setColor(0xffffff);
    gr.fillArc(0, 0, placeholderForProfile.getWidth(), placeholderForProfile.getHeight(), 0, 360);

    URLImage.ImageAdapter ada = URLImage.createMaskAdapter(roundMask);

    AllUrl au = new AllUrl();
    Image getProfileImage = URLImage.createToStorage(placeholderForProfile, "profile.png",
            au.profileImgUrl + profile_img, ada);
    profileImg.setIcon(getProfileImage);
}

模拟器出错：

Answer 1

蒙版和占位符的大小应完全匹配。你在掩码上调用scaled，如果大小已经相同则可能没有效果，但如果不是，则会严重失败。

当使用特定大小的图像时，RoundMask会出现异常
