[ka-Map-users] JPEG output (and caching)

[Jacob Delfos]

Armin,

Thanks, this fixed it. The application works great with jpg. I just had to add the missing leading $ :) 
I could play with this application forever.....

Regards,

Jacob

Jacob,

this problem should be related to the line 109 in tile.php:

  $szCacheFile = $szCacheDir."/".$szTileId.".png";

Here the image extension is hardcoded and the browser cannot find the JPEG
files because it looks for PNG's. I modified it to 

  szCacheFile = $szCacheDir."/".$szTileId.$GLOBALS['szImageExtension']; 

and it worked fine for JPEG definition.

MESSAGE FROM jacob.delfos at maunsell.com:
------------------------------------------
I tried to configure it to output JPEG, having set the type to JPEG, and
changed imagepng to imagejpeg. But I only get broken images (both explorer
and firefox), even at the first load (where PNG did work). Looking in the
directory, it does seem to have created a number of jpeg images, but these
did not appear in the browser.

Another thing I can into: after changing to JPEG, I had to force the browser
to delete all temp files, because even with a shift-refresh it was showing
the old PNG files (which were not even in the temp directory anymore). I can
see how that would be a problem if the map content is updated. 

Regards,

Jacob
