Is world_map_med.gd2 a truecolor image? This function does nothing if the image has a palette. Previous Comments: ------------------------------------------------------------------------ [2002-10-06 12:18:35] [EMAIL PROTECTED] imagetruecolortopalette() is: void imagetruecolortopalette ( resource image, bool dither, int ncolors) but the function seems to ignore my ncolors input. ncolors should be the maximum number of colors in the output image. (and I cannot tell if dither works) Test script: <?php header( "Content-type: image/png" ); $medimg = $_SERVER['DOCUMENT_ROOT'] . "/riverdata/images/world_map_med.gd2"; $img = ImageCreateFromGD2Part( $medimg, 900, 500, 800, 600 ); //Avoid bug #19418 $medimg = ImageCreateTrueColor( 800, 600 ); ImageCopy( $medimg, $img, 0, 0, 0, 0, 800, 600 ); ImageDestroy( $img ); $img = $medimg; ImageTrueColorToPalette( $img, FALSE, 2 ); ImagePNG( $img ); ImageDestroy( $img ); ?> You can find the GD2 image that I am using here: http://144.92.10.251/riverdata/images/world_map_med.gd2 The previous episode in this saga can be seen here: http://bugs.php.net/bug.php?id=19704 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19781&edit=1
