Yes, Armin you're right, here is the patch for zoombox: Insert after http://svn.pmapper.net/trac/browser/pmapper/trunk/incphp/map.php#L483 // ABP: check scale $x_pix = ($pix_maxx + $pix_minx) / 2; $y_pix = ($pix_maxy + $pix_miny) / 2; $xy_pix = ms_newPointObj(); $xy_pix->setXY($x_pix, $y_pix); $minscale = $this->map->web->minscale; $zoom_factor = $this->mapwidth / ($pix_maxx - $pix_minx); if($zoom_factor < 1){ $zoom_factor = - 1 / $zoom_factor; } //error_log("$zoom_factor"); $new_scale = ($zoom_factor > 0) ? $this->old_geo_scale / $zoom_factor : $this->old_geo_scale * ( - $zoom_factor); //error_log("$new_scale < $minscale"); if($zoom_factor != 1 && $this->old_geo_scale && $new_scale < $minscale){ return $this->map->zoomscale($minscale + 0.1, $xy_pix, $this->mapwidth, $this->mapheight, $this->geoext0, $this->maxextent); } // ABP: End ------------------------------- Also a small fix to the previous zoompoint patch: Insert after http://svn.pmapper.net/trac/browser/pmapper/trunk/incphp/map.php#L519 // ABP: check scale $minscale = $this->map->web->minscale; //error_log($minscale); //error_log($this->zoom_factor); $new_scale = ($this->zoom_factor > 0) ? $this->old_geo_scale / $this->zoom_factor : $this->old_geo_scale * ( - $this->zoom_factor); //error_log($this->old_geo_scale); if($this->zoom_factor != 1 && $this->old_geo_scale && $new_scale < $minscale){ return $this->map->zoomscale($minscale + 0.1, $xy_pix, $this->mapwidth, $this->mapheight, $this->geoext0, $this->maxextent); } //*/ -- Alessandro Pasotti itOpen - "Open Solutions for the Net Age" w3: www.itopen.it Linux User# 167502 ------------------------------------------------------------------------- Take Surveys.
