Hi Rahkonen, Thanks for your precise observations. 1) It seems that the image disappears when it does not cover the whole view panel and the image pixel is larger than one screen pixel. 2) Moreover, when this situation occurs, an error is thrown and the image is no more accessible, even if we zoom in after
For the second problem, I deactivated the error so that if the image disappears after a zoom, it will appear again if one zoom out (not yet committed) I still don't know if the first problem comes from jump's code (bad bounding box calculation), or from ermapper's code. If anybody has the ecw dll and/or java wrapper documentation, it could help. I did not find it anymore on ER Mapper's site Michaël Rahkonen Jukka a écrit : >> Lähettäjä: Giuseppe Aruta [mailto:[EMAIL PROTECTED] >> >> Hi all, >> I want to give my opinion to some argumats from Michael, even >> if I am not a programmer but a big user of OJ >> >> IMAGE >> >> Images still represent a problem with embedded raster plugin >> in OpenJUMP: a raster image has a tendency to dissapear when >> zooming in/out several times on it. >> Some times ago (if I am, not wrong) there was a discussion >> about integrate Pirol Baseclass.jar in OpenJUMP which seems >> to handle better the raster (the image never dissapears and >> there is also trasparency). >> > > I am rather sure that this image disappearense happens only when zooming to > an area that is partly outside the image area.
