Would you please ensure using Aspose.PDF for Java 19.8 and then share your kind feedback with us if the issue persists.

@pape

Thank you for elaborating further.

Please note that getLocalFontPaths and setLocalFontPaths are now exposed by FontRepository class. You may refer to API references for your kind reference and then share your kind feedback with us.

String path = "D:\\Test\\Fonts\\";
List<String> fontPaths = FontRepository.getLocalFontPaths();
fontPaths.add(path);
FontRepository.setLocalFontPaths(fontPaths);

Thnak for you response.

Farhan.Raza · September 19, 2019, 9:23pm

@pape

Yes, Aspose.PDF API can be used in Docker container. Would you please elaborate if you are facing this problem with a specific file or with every file. Moreover, the code snippet you had referred to, in your previous reply is now obsolete and should be replace by the code suggested by us above.

@Farhan.Raza
I found a problem to fixe a bug for openjdk:8-jre-alpine distribution
To solve this bug it should run this command to a docker container
RUN apk --no-cache add msttcorefonts-installer fontconfig &&
update-ms-fonts &&
fc-cache -f

Thank
