Hi everyone,
pdf.js is great! Was just wondering what I need to do in order to get all images of a page in node.js .
Seems the API is not quite there yet?
Maybe you could give me a hint how to accomplish that.
Thanks a lot
Andreas

At the moment you have to use getOperatorList (see https://github.com/mozilla/pdf.js/blob/master/src/display/api.js#L1033 and SVG converter as example at https://github.com/mozilla/pdf.js/blob/master/examples/svgviewer/viewer.js#L39). There are multiple ways images might be stored in the PDF: as JPEG with or without mask, as PNG, as scanned pages, as a BW bitmap data and as a pattern, sometime might be split into small several pieces. Please find the type of images used in your files and process only needed operations from the operator list. Closing as answered. Recovering of the original images from the PDF has little value for the viewer, so as is this requirement is out-of-scope of this project.
