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的捕获软件基于Chromium，因此，如果URL或HTML在Chrome中的呈现效果不佳，就无法很好地捕获它。

图像质量

默认情况下，图像捕获使用JPG，默认情况下使用85％压缩来降低质量，但图像尺寸较小。为了提高质量，您需要将图像格式更改为默认JPG以外的其他格式，例如PNG，这样可以很好地兼顾压缩和质量。或保持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.URLToImage("http://www.spacex.com", options);
grabzIt.Save("http://www.mywebsite.com/handler");

<script>
GrabzIt("Sign in to view your Application Key").ConvertURL("http://www.spacex.com", 
{"quality":100}).Create();
</script>

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;
    }
});

$options = GrabzItImageOptions->new();
$options->quality(100);

$grabzIt = GrabzItClient->new("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/handler.pl");

$options = new \GrabzIt\GrabzItImageOptions();
$options->setQuality(100);

$grabzIt = new \GrabzIt\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/handler.php");

options = GrabzItImageOptions.GrabzItImageOptions()
options.quality = 100

grabzIt = GrabzItClient.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/handler.py")

options = GrabzIt::ImageOptions.new()
options.quality = 100

grabzIt = GrabzIt::Client.new("Sign in to view your Application Key", "Sign in to view your Application Secret")
grabzIt.url_to_image("http://www.spacex.com", options)
grabzIt.save("http://www.mywebsite.com/handler/index")

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大小增加或减小图像大小。虽然我们使用最佳的缩放算法，但仍然可以实现质量，这通常是由于开发人员为图像选择了错误的缩放比例.

图像打印int 真诚

如果你想公关int 图像越大，图像尺寸越大，图像质量越高inted。为此，无需拉伸图像GrabzIt可以创建高清晰图像缩放图像以提供更多细节。

DOCX质量

可以通过为要转换的文档类型设置质量参数来提高DOCX中存储的图像的质量，以下示例显示了如何将DOCX的质量设置为100。

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

DOCXOptions options = new DOCXOptions();

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

GrabzIt("Sign in to view your Application Key").ConvertURL("http://www.spacex.com",

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_docx("http://www.spacex.com", {"quality":100});
client.save("http://www.example.com/handler", function (error, id){
    if (error != null){
        throw error;

$grabzIt = GrabzItClient->new("Sign in to view your Application Key", "Sign in to view your Application Secret");
$grabzIt->URLToDOCX("http://www.spacex.com", $options);

$grabzIt->URLToDOCX("http://www.spacex.com", $options);
$grabzIt->Save("http://www.mywebsite.com/handler.php");

options.quality = 100

grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret")
grabzIt.URLToDOCX("http://www.spacex.com", options)
grabzIt.Save("http://www.mywebsite.com/handler.py")

options = GrabzIt::DOCXOptions.new()
options.quality = 100

grabzIt = GrabzIt::Client.new("Sign in to view your Application Key", "Sign in to view your Application Secret")
grabzIt.url_to_docx("http://www.spacex.com", options)
grabzIt.save("http://www.mywebsite.com/handler/index")

PDF质量

默认情况下，GrabzIt生成的PDF使用最佳压缩，可确保压缩PDF而不损失质量。但是，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quality参数设置为100来提高Animated GIF的质量。增加帧率也将提高GIF的质量。

请注意，要使用大多数这些技术，还需要高级套餐.
