Mac电脑上指定字库报异常

我用的是mac电脑, 一下是我的程序

   FontSettings.addFontsFolder("/System/Library/Fonts");
    Document pdfDocument = new Document("/Volumes/下载/386.pdf");
	// Loop through all the pages of PDF file
	for (int pageCount = 1; pageCount <= 4; pageCount++) {
		// Create stream object to save the output image
		java.io.OutputStream imageStream = new java.io.FileOutputStream("/Volumes/下载/Converted_Image" + pageCount + ".jpg");
		// Create Resolution object
		Resolution resolution = new Resolution(300);
		// Create JpegDevice object where second argument indicates the quality of resultant image
		JpegDevice jpegDevice = new JpegDevice(resolution, 100);
		// Convert a particular page and save the image to stream
		jpegDevice.process(pdfDocument.getPages().get_Item(pageCount), imageStream);
		// Close the stream
		imageStream.close();
	}

以下是报的异常

请问 在mac的字库不能识别,只能用windows字库吗?

@mxudong

您能否分享示例 PDF 文件以供我们参考,以便我们可以在我们的环境中测试该场景并相应地解决它?

其实和文档无关, 只要是中文文档就会有这个问题, 当然给你们pdf没问题. 关键是 windows上能跑, mac上跑不了386.pdf (1.3 MB)

我在 MAC OS 上复制了异常,并在我们的问题跟踪系统中创建了 ID PDFJAVA-40683 的票证,以进一步调查和解决问题。 此线程已与问题相关联,以便在问题解决后您可能会收到通知。
