您如何提高网络捕获的质量？

在判断捕获的质量之前，必须明确 GrabzIt 的捕获软件是基于 Chromium 的，因此如果 URL 或 HTML 在 Chrome 中不能很好地呈现，就不会被很好地捕获。

图像质量

默认情况下捕获的图像使用 JPG，默认情况下使用 90% 压缩以降低质量，但图像尺寸较小。要提高质量，您需要将图像格式更改为默认 JPG 以外的格式，例如 PNG，这样可以在压缩和质量之间取得良好的平衡。或者保留 JPG 格式并将质量参数设置为 100，如下所示，尽管这会增加文件大小。

ImageOptions options = new ImageOptions();
options.Quality = 100;

GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
grabzIt.URLToImage("http://www.spacex.com", options);
grabzIt.Save("http://www.mywebsite.com/Home/Handler");

ImageOptions options = new ImageOptions();
options.setQuality(100);

GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");

grabzIt.Save("http://www.mywebsite.com/handler");

var grabzit = require('grabzit');

var client = new grabzit("Sign in to view your Application Key", "Sign in to view your Application Secret");
client.url_to_image("http://www.spacex.com", {"quality":100});
client.save("http://www.example.com/handler", function (error, id){
    if (error != null){
        throw error;
    }

缩放屏幕截图可能会导致另一个潜在的质量问题。这意味着相对于浏览器的大小增加或减少图像大小。虽然我们使用最好的缩放算法，但质量仍然会受到影响，这通常是由于开发人员为图像选择了错误的缩放比例.

图像处理int 质量保证

如果你想公关int 图像尺寸越大，可以打印的图像质量越高int编辑。要在不拉伸图像的情况下执行此操作，GrabzIt 可以创建高清图片图像被缩放以提供更多细节。

DOCX 质量

可以通过设置要转换的文档类型的质量参数来提高 DOCX 中存储的图像的质量，下面的示例显示如何将 DOCX 的质量设置为 100。

PDF质量

GrabzIt 生成的 PDF 默认情况下使用最佳压缩，这可确保 PDF 被压缩而不会损失质量。然而，小于 50 的质量值将导致 GrabzIt 完全压缩 PDF。

GIF 动画质量

您还可以通过将质量参数设置为 100 来提高动画 GIF 质量，另外提高帧速率还将提高 GIF 的质量。

请注意，要使用大多数这些技术还需要高级套餐.
