[MapProxy] blurred labels when requesting more layers from mapproxy

[Sandor Csaba]

Hi list,

I have 3 caches for 3 mapserver layers in my mapproxy.yaml.

This is generated by mapproxy when requesting one layer:

http://webmap.viamap.hu/upload/014.png

This is generated when requesting all 3 layers (including the previous one)
of which 2 are completely empty at that location:

http://webmap.viamap.hu/upload/service.png

Something happens when mapproxy merges the images from the 3 separate
caches.

Here's the global part of mapproxy.yaml:

globals:
  # # cache options
  cache:
    # where to store the cached images
    base_dir: './cache_data'
    # where to store lockfiles
    lock_dir: './cache_data/locks'
  #   # request x*y tiles in one step
    meta_size: [1, 1]
  #   # add a buffer on all sides (in pixel) when requesting
  #   # new images
    meta_buffer: 0

  # image/transformation options
  image:
      formats:
        image/png:
          resampling_method: bilinear
          mode: RGB
          transparent: true
      resampling_method: nearest
      paletted: false
  #     jpeg_quality: 90
  #     # stretch cached images by this factor before
  #     # using the next level
  #     stretch_factor: 1.15
  #     # shrink cached images up to this factor before
  #     # returning an empty image (for the first level)
  #     max_shrink_factor: 4.0


Tried to play with image options with no luck. Can you suggest any starting
points in getting this right?

Thanks,
Csaba
