Suggestion: Image not rendering inside JAR in container Docker

[jcarlosvale]

Hello, I spent some time to be able to generate a PDF using an image (in the resources) inside a JAR deployed in Docker. In the localhost it was OK but when the service was deployed the image was not working. Because it is necessary to have write permissions in the tmp folder. In our case is prohibitive to change the file permissions, so it was necessary to change the ImageIO to not use cache file. Change used: -> ImageIO.setUseCache(false);

As a suggestion: to allow in the PdfRendererBuilder change to use cache or not like the useFastMode( )
