batik-rasterizer.jar - 将svg转换为png [英] batik-rasterizer.jar - convert svg to png

问题描述

我尝试在我的linux服务器中使用以下命令设置导出服务器，以便从 Highcharts 。

I was try yo setup an export server in my linux server with the following command to download graph as image from Highcharts.

$command = "java -jar batik-rasterizer.jar -m image/png -d temp/1a6b5dd08ec607454b81f91097fb24a6.png temp/1a6b5dd08ec607454b81f91097fb24a6.svg 2>&1 "; 
$output = shell_exec($command);
echo "Command: $command <br>";
echo "Output: $output";

它在我的本地Windows机器中完美地创建了一个图像，但我将它上传到我的linux服务器中，我我收到错误。

It creates an image in my local windows machine perfectly ,But i uploaded it in my linux server,I am getting errors.

 About to transcode 1 SVG file(s) Converting 1a6b5dd08ec607454b81f91097fb24a6.svg to temp/1a6b5dd08ec607454b81f91097fb24a6.png ... (.:21519): Gtk-WARNING **: cannot open display:

为什么会发生这种情况？

Why this happens?

我注意到图像是使用0 kb无效图像创建的

And i notice that an image is created with 0 kb invalid image

注意： 我也尝试了以下方法。

1）包含蜡染的文件夹-rasterizer.jar和文件的所有者为root，权限设置为777。

1)folder containing batik-rasterizer.jar and the files have owner as root and permission is set as 777.

2）我也尝试用 / user / bin /执行它java ，哪个java insted pf java 命令。

2)i also try to execute it with /user/bin/java , which java insted pf java command.

3）我也尝试执行此操作使用putty使用终端以root身份命令，Java安装在我的服务器中r。

3)I also try to execute this command as root using terminal using putty,Java is installed in my server.

推荐答案

使用执行java -Djava.awt.headless = true 命令行选项：

$command = "java -Djava.awt.headless=true -jar batik-rasterizer.jar -m image/png -d temp/out.png temp/in.svg 2>&1 "; 

更新

如果传递附加命令行选项仍未产生预期结果，请检查Java版本。将JRE更新为更新版本（1.7）也可能会解决问题。

If passing the additional command-line option still does not yield the expected result, check your Java version. Updating your JRE to a more recent version (1.7) might also resolve the issue.
