Re: [mapserver-users] MapServer returns a blank image when requesting a square image

2018-01-11 Thread Pablo Sanfilippo 
I'm actually using MapServer 7.1 and it works fine as long as I'm using
4326 to request the tiles (whatever projection the sources of tileindex are
in). The problem is when I make the request using 3857 and the height of
the image is greater or equal to the width.

I'm going to try and make that zip.

About explicit PROJECTION blocks, actually yes. I forgot about mentioning
that. It works fine when explicitly setting the PROJECTION in the raster
layer. However, I can't do that because the files referenced by the
tileindex are in different projections.

Re: [mapserver-users] MapServer returns a blank image when requesting a square image

2018-01-11 Thread Rahkonen Jukka (MML) 
Hi,

I have been using a spatialite layer as a tileindex for years without problems 
so definitely that is not a bug that affects all users and use cases. Try to 
create a zip file that contains everything that is needed for reproducing the 
issue. Let’s hope that you can make it with a spatialite database and two 
images in the tileindex.

Have you already tried to add explicit PROJECTION blocks into both LAYERs?

A WMS request for the index layer shows the index polygons fine, whatever the

A WMS request for the images layer using SRS=EPSG:4326 shows the images fine,

A WMS request for the images layer using SRS=EPSG:3857 will work fine as long

Any clues?

Hi Pablo,

Just to note I also ran into this issue so you are not alone!
A WMS request from OpenLayers to MapServer would be fine, but modifying
the size of the image (WIDTH and HEIGHT parameters) would result in a
blank image and no errors in the logs.I never got a chance to debug further 
though. An error should ideally be
reported somewhere rather than a blank, seemingly valid, image.

[mapserver-users] MapServer returns a blank image when requesting a square image

2018-01-10 Thread Pablo Sanfilippo 
Hi all,

I admit this is the weirdest issue I have come across. This are the
relevant parts of my MapServer configuration:

# A valid mapfile used for testing
MAP
  NAME valid
  STATUS ON
  PROJECTION
"init=epsg:4326"
  END

  IMAGECOLOR 0 0 0
  TRANSPARENT ON

  WEB
METADATA
  "wms_srs" "EPSG:4326 EPSG:3857"
  END
  END

  LAYER
NAME "index"
STATUS ON
TYPE POLYGON
CONNECTIONTYPE POSTGIS
CONNECTION "host=x port=x dbname=x user=x password=x"
DATA "geometry from (select i.geometry, i.id, '/vsis3/' || i.s3_bucket
|| '/' || i.s3_key as location from images_image) as index using unique id"
CLASS
  STYLE
OUTLINECOLOR 0 0 0
WIDTH 1.0
COLOR 200 200 200
ANTIALIAS true
  END
END
  END

  LAYER
NAME "images"
STATUS ON
TILEINDEX "index"
TILEITEM "location"
TYPE RASTER
PROJECTION
  AUTO
END
METADATA
  "wms_title"   "Images"
END
  END


END

The data in the PostGIS index is in EPSG:4326. The images referenced by the
index are GeoTIFFs georeferenced in EPSG:4326.

A WMS request for the index layer shows the index polygons fine, whatever
the SRS and image size in the request.
A WMS request for the images layer using SRS=EPSG:4326 shows the images
fine, whatever the image size.
A WMS request for the images layer using SRS=EPSG:3857 will work fine as
long as the requested image size's x is greater than or equal to the y. If
not, it will return a blank (transparent) image. For example, a 1300x1299
image will work fine, a 1300x1300 image won't work and 1301x1300 won't work
either.

Any clues?

Thanks!
