Examples with Resource org.apache.xmlgraphics.io.Resource used on opensource projects

Example 1 with Resource

use of org.apache.xmlgraphics.io.Resource in project xwiki-platform by xwiki.

the class PDFResourceResolver method getResource.

@Override
public Resource getResource(URI uri) throws IOException {
    XWikiContext xcontext = xcontextProvider.get();
    Map<String, AttachmentReference> attachmentMap = (Map<String, AttachmentReference>) xcontext.get(PdfURLFactory.PDF_EXPORT_CONTEXT_KEY);
    if (attachmentMap != null) {
        String uriString = uri.toString();
        // implemented for TemporaryResource...
        if (uriString.contains(TEX_ACTION)) {
            // Note: See the comments in FormulaMacro to understand why we do a replace...
            AttachmentReference reference = attachmentMap.get(uriString.replace(TEX_ACTION, "/download/"));
            if (reference != null) {
                // Get the generated image's input stream
                ImageStorage storage = Utils.getComponent(ImageStorage.class);
                ImageData image = storage.get(reference.getName());
                return new Resource(new ByteArrayInputStream(image.getData()));
            }
        }
        // TODO: end HACK
        AttachmentReference reference = attachmentMap.get(uriString);
        if (reference != null) {
            try {
                XWikiDocument xdoc = xcontext.getWiki().getDocument(reference.extractReference(EntityType.DOCUMENT), xcontext);
                // TODO: handle revisions
                XWikiAttachment attachment = xdoc.getAttachment(reference.extractReference(EntityType.ATTACHMENT).getName());
                return new Resource(attachment.getContentInputStream(xcontext));
            } catch (Exception e) {
                throw new IOException(String.format("Failed to resolve export URI [%s]", uriString), e);
            }
        }
    }
    return this.standardResolver.getResource(uri);
}

Example 2 with Resource

        @Override
        public Resource getResource(URI uri) throws IOException {
            String asciiUri = uri.toASCIIString();
            InputStream is = PdfTransformer.class.getClassLoader().getResourceAsStream(asciiUri);
            if (is == null && uriResolver != null) {
                try {
                    StreamSource streamSource = (StreamSource) uriResolver.resolve(asciiUri, null);
                    if (streamSource != null) {
                        is = streamSource.getInputStream();
                    }
                } catch (TransformerException e) {
                    throw new IOException(e);
                }
            }
            return is == null ? null : new Resource(is);
