Thanks for the code Raj, saved me.
If it's useful to anyone else, based on your sample I wrote a general
purpose URL->PDF function that will search the HTML for any dependent
images and insert them, only external dependency is commons.io
-Casey
String content = IOUtils.toString(new
URL(url).openStream());
Asset asset = new Asset("text/html", content.getBytes(),
"in.html");
Matcher m = Pattern.compile("<img[^>]*src=\"([^\"]*)",
Pattern.CASE_INSENSITIVE).matcher(content);
List<Asset> assetsList = new ArrayList<Asset>();
assetsList.add(asset);
while (m.find()) {
String relative = m.group(1);
URL absolute = new URL(new URL(url), relative);
byte[] image_data =
IOUtils.toByteArray(absolute.openStream());
String guessedContentType = null;
if (relative.toLowerCase().endsWith(".png")) {
guessedContentType = "image/png";
} else if (relative.toLowerCase().endsWith(".jpg")) {
guessedContentType = "image/jpeg";
} else if (relative.toLowerCase().endsWith(".gif")) {
guessedContentType = "image/gif";
}
Asset subAsset = new Asset(guessedContentType == null
|| response.getContentType() != null ? response.getContentType() :
guessedContentType, image_data, relative);
assetsList.add(subAsset);
}
Document document = new Document(assetsList);
Conversion conversion = new Conversion(document,
"application/pdf");
ConversionService service =
ConversionServiceFactory.getConversionService();
ConversionResult result = service.convert(conversion);
if (result.success()) {
response.getOutputStream().write(result.getOutputDoc().getAssets().get(0).getData());
} else {
logger().severe(result.getErrorCode().name());
response.getOutputStream().write(result.getErrorCode().name().getBytes());
}
