OKMindmap is a great web-based mindmap. It provides many different format conversion and import/export functions. Because it uses many kinds of different API for other service integration, sometimes it is not easy to catch up other service or standard changes. One of the services is export to the image of OKMindmap now. We used an open source library and now some changes in the library make it hard to get a successful image export result.
Fortunately, OKMindmap is based on SVG and it is possible to export it to SVG. Then the user can modify the SVG file with SVG editor and even produce an image or a pdf file. There are many free SVG online editors on the Internet, and I suggest to use Vector Painter. User can upload SVG file exported form OKMindmap directly here. User can edit and export the image.
Some of the images will not appear because it is provided as a web image. OKMindmap allows to embed web-based images, but this is not shown in the SVG editor printed result. It is necessary for the user to embed the image as data: type. Though this surely occupies more data file of OKMindmap, but resolves the problem of not being able to print the image component. User can convert the local or Internet image on askApache service. Please, watch the video.
