Hi,I'm trying to incorporate a PNG image to a container.This image has a transparent background but when I add it to the container it becomes white. Any idea what can do such thing ?My code is looking something like this :
IPageLayout pageLayout = ((MapServer)mapserver).getPageLayout();
IGraphicsContainer container = (IGraphicsContainer) pageLayout;
PngPictureElement pngPicElem = (PngPictureElement) this.currentRequestServerContext.createObject(PngPictureElement.getClsid());
pngPicElem.importPictureFromFile(imgResult.getURL());
container.addElement(pngPicElem, 0);
I have tried to manually set the background of my element but with no success :
IColor color = (IColor) (this.currentRequestServerContext.createObject(RgbColor.getClsid()));
color.setTransparency((byte) 0);
color.setRGB(0xFF0000);
SymbolBackground symbBg = (SymbolBackground) this.currentRequestServerContext.createObject(SymbolBackground.getClsid());
symbBg.setColor(color);
pngPicElem.setBackground(symbBg);
Thank you.N.B. I'm using Java ArcObjects SDK on ArcGIS Server 10
