[gdal-dev] GDAL Overviews selection

2012-12-10 Thread HariPrasad
Iam writing a custom GDAL driver (RBD format). I was able to display the base image (overview no = -1) but for a big image(5 GB) it takes huge amount of time. So i was displaying its overview (ex; image has 3 overviews and i always displays the last overview). In this case ArcGIS 10 displays

[gdal-dev] Multiple pens in OGR feature style

2012-12-10 Thread Marco Hugentobler
Hi I'm currently implementing support for OGR feature styles in the QGIS vector layer export. In QGIS symbology, there is the possibility to compose a symbol with multiple symbol layers, e.g. a broad black line with a thin white line on top of it for a road symbol. Is this supported by the OGR

Hi Even Ok, so it seems to depend on the format properties. Hi Even You are right, it seems to depend on the output driver/format. Actually my main interest is the dxf format, it seems that one takes the first element of the style. Don't know if there are drivers which handle multiple

Hi Marco and others, If the (DXF) writer does not support multiple strokes - can you perhaps export the same feature multiple times using the corresponding OGR features styles? Ideally, this would honour the symbol levels, if defined, in QGIS to get the same symbology. Do you think this is

i never considered this possibility when writing the libkml driver. perhaps check what mapserver does?. there is not a lot that uses featurestyle. perhaps a clarification of this in the spec is in order? brian On Mon, 2012-12-10 at 09:34 -0700, David Strip wrote: On 12/10/2012 7:29 AM, Even
