hi all, I need to overlay two or more images from server-side (PHP) coming from diferent WMS GetMaps (as I need to create these requests using dynamically created SLDs for different layers I cannot integrate everything on the same Getmap). In these GetMaps I include the Transparent=true parameter.
I'm using imagecopymerge from GD php's library to overlay the images. One of the parameters of this function is a percentage (of pixels of the second image to be printed over the second image). The problem is that it means losing brightness. You can check this URL (as in Mexico there are more than one layer overlayed, it appears without brightness) http://edit.csic.es/fitxers/TDWG_distributions.php?ad=tdwg2/c:Brazil,Mexico,Caribbean|b:Mexico||tdwg4/c:Nicaragua,Chiapas,Oaxaca,Veracruz||tdwg3/a:MXC,|b:MXE,MXG|d:VEN|c:MXT,&as=a:d7add2|b:ab8dc9F|c:f2e227|d:f7555d&ms=700x450 Some idea? some similar function in PHP (or not...) to solve it? thanks! -- Pere Roca Ristol Biòleg i especialista GIS Museo Nacional de Ciencias Naturales (CSIC) Visita l'EDIT mapViewer! http://edit.csic.es/edit_geo/prototype/edit.html
