<s:graphicImage> should accept raw byte[] without conversion
------------------------------------------------------------
Key: JBSEAM-1592
URL:
http://jira.jboss.com/jira/browse/JBSEAM-1592
Project: JBoss Seam
Issue Type: Feature Request
Components: JSF
Affects Versions: 2.0.0.BETA1, 1.3.0.ALPHA, 1.2.1.GA
Environment: latest from repo
Reporter: Gena Batalski
Priority: Minor
It would be helpful to feed the <s:graphicImage> with raw byte[] (possible also
ByteArray - stream) without converting it to BufferedImage or something else. Also the
content type could be manually entered. Of course, its in the responsibility of the
developer, to take care about the correctness of input. Optional attributes
(forceContentType, forceImage or something else) could do this job on the UI side.
Background of the request:
if i comment out the byte[] handling in Image.class (line 404 method readImage()) as in a
following snipplet, i get an expected quality. Otherwise, the image quality decreases
significantly, especially for small images (icons, thumbnails).
/*
byte[] b = (byte[]) input;
readImage(new ByteArrayInputStream(b));
*/
output = (byte[]) input;
I also would have some possibility, to prepare the image on demand. Currently i'm
using two servlets: one SeamResource and one for my images. My servlet receives an URI and
selects an image LOB from DB, because it isn't necessary to store the images in memory
(they could be large) and the images could stay unrequested. What i need is some kind
callback (converter?) which asks me for byte[] or stream representation of an image uri.
Thanks
