Hi,
I am working with java/mapscript and am trying to convert an
edu.umn.gis.mapscript.imageObj into some kind of java image object (ideally
something that implements java.awt.image.RenderedImage but anything would
be a start). This is so I can manipulate the image, using JAI and java2d,
and then stream the modified image as a SOAP message response.
At the moment I am saving the image to a temporary file (java code shown
below), using the imageObj.save() method, and then reloading that image into
my java object. This is not a desirable solution for obvious performance
and scalability reasons especially as I seem to need to pause after the
save to avoid the load command giving intermittent errors.
Does anybody have any experience of converting the imageObj into a more
useful java object? Has anyone written a java or c method to aid this, or
found another way round a similar problem?
Regards,
James
---Java code snippet---
imageObj image = mapobj.draw(); //define imageObj
String filename = "/var/www/html/gis/scratch/maptemp.png";
File filefilename = new File(filename); // set temp file variables
image.save(filename, mapobj); // save image to disk
Thread.sleep(1000); // pause to ensure has saved - avoids errors
BufferedImage bufimg = ImageIO.read(filefilename); // load it again
