Hi, a similar question was posted lately... somewhere (can't remember if here or on stackoverflow).
Basically what seems to be happening (from a cursory look in the code), is that rendering transformations generating raster data do not benefit from the "advanced projection handling" and "dateline wrapping" machinery, as such they can only render the true source locations, but do not get replicated across the dateline. If you want, you can open a ticket on our bug tracker and ask for an improvement on this. The best way to get the change actually happen in the short term is to either code it yourself (I can give you pointers on how that could be done) or sponsor someone to do it for you, you can check http://geoserver.org/support/ Cheers Andrea On Sat, Nov 24, 2018 at 12:47 AM Lubomír Bucek <[email protected]> wrote: > Hello! > I am not really sure if this is the right place to report it, or geotools > repository would be more appropriate. > I am using Ras:Jiffle operation on GeoServer layer in SLD style, but when > the processing area of Ras:Jiffle is larger than SRS bounds - crossing > datetime line for webmercator for example, the raster is visible only > inside the SRS bounds, even though other elements are correctly visible. > First image shows global pressure with cut raster on date line. > (webmercator) This example layer uses Jiffle. > https://www.dropbox.com/s/7yi3fg1zjb58fed/pressure.png?dl=0 > Second image shows global temperature.
