尝试过以下方案，输出的图片文字都不显示了：

字体替换策略
final SystemFontsSubstitution systemFontsSubstitution = new SystemFontsSubstitution(1);
systemFontsSubstitution.setDefaultFont(FontRepository.findFont(“Arial”));
FontRepository.getSubstitutions().add(systemFontsSubstitution); -
JpegDevice, 设置RenderingOptions
JpegDevice jpegDevice = new JpegDevice(50);
final RenderingOptions renderingOptions = new RenderingOptions();
jpegDevice.setRenderingOptions(renderingOptions);
renderingOptions.setDefaultFontName(“Arial”);
