Add in items multiple images

[andybuki]

Hi i use your jiiify-presentation V3.0 to create manifests from my json files.
I try to add all pages/images of a book to manifest.

manifest.setCanvases(LIST_OF_CANVAS));
Unfortunately i add only the last ellement of the list.
Can you advice me how should it look like?

My code looks:

       `String manifestID ="";
        String canvasID ="";
        String annoID ="";
        String imageID ="";
        String annoPageID ="";

        Canvas canvas = new Canvas("");
        AnnotationPage<PaintingAnnotation> annoPage = new AnnotationPage<>("");
        PaintingAnnotation anno = new PaintingAnnotation("",canvas);
        ImageContent imageContent = new ImageContent("");
        List<Canvas> canvases;


        for (int j = 0; j < pages.length(); j++) {
            JSONObject pagesObj = (JSONObject) pages.get(j);

            String pages_position="";
            String pages_image_file="";
            String pages_id="";
            String pages_document_id="";
            int number_of_pages = pages.length();

            if (pagesObj.has("pages_position"))
                pages_position = (String) pagesObj.get("pages_position").toString();

            if (pagesObj.has("pages_image_file"))
                pages_image_file = (String) pagesObj.get("pages_image_file").toString();

            if (pagesObj.has("pages_id"))
                pages_id = (String) pagesObj.get("pages_id").toString();

            if (pagesObj.has("pages_document_id"))
                pages_document_id = (String) pagesObj.get("pages_document_id").toString();

            JSONObject json = readJsonFromUrl("https://iiif-content.crossasia.org/xasia/dllm"+"+dllm_000"+pages_document_id+"+"+pages_id+"/info.json");

            manifestID = SERVER + MANIFEST_COLLECTION + "000" + pages_document_id +"+"+ pages_id;
            canvasID = manifestID +"/canvas";
            imageID = manifestID+"/full/full/0/default.jpg";
            annoID = manifestID+"/annotation";
            annoPageID = manifestID;

            canvas = new Canvas(canvasID).setWidthHeight((Integer) json.get("width"), (Integer) json.get("height"));

            imageContent = new ImageContent(imageID).setWidthHeight((Integer) json.get("width"), (Integer) json.get("height"));
            annoPage = new AnnotationPage<>(annoPageID);
            anno = new PaintingAnnotation(annoID, canvas);
            annoPage.addAnnotations(anno.setBody(imageContent).setTarget(canvasID));

            manifest.setCanvases(canvas.setPaintingPages(annoPage));
        }`

Best regards

Hi, i allready found, how to solve it. Sometimes just to do it next day.

Glad you found the solution already. That's always the way it goes, isn't it? Put it down for a bit and the answer comes :-)

I should probably leave a little more explanation for the next person that comes along and reads this. The setCanvases() method sets all the canvases at once, so if you put it into a loop like the above only the last canvas is actually getting set.

The way I'd do it is to create a list of canvases outside the loop and add to that list in the loop, finally using setCanvases(list) once the loop is done with its work; or, alternatively, you could do something like manifest.getCanvases().add(canvas) inside the loop, which would add one canvas to the manifest's internal list of canvases on each iteration.
