Hi,
ImageColorResolve() doesn't solve it - but you will be happy to know that I
did solve it - form your palette tip.
Guessing that the color is not in the palette, use:
imagecolorset($image,1,255,100,100);
to force your color into the palette.
So, this works:
*********************************
<?php
header ("Content-type: image/png");
$text=implode($argv," ");
$image=imageCreateFromPNG("basic.png");
imagecolorset($image,1,255,100,100);
$text_color=imageColorAllocate($image,255,100,100);
$textX=(imageSX($image)-imageFontWidth(4)*strlen($text))/2;
imageString($image,5,$textX,10,$text,$text_color);
imagePNG($image);
imageDestroy($image);
?>
*********************************
Thanks for the help.
P.S. I spotted a couple of spelling mistakes in the PHP manual. In cpdf_save
and cpdf_restore, you write 'enviroment'. The correct spelling is
'environment'. (Mind you - this is English, not American').

I'm not a PNG expert but you could try ImageColorResolve() The palette used
in 'basic.png' may be different than you expect.

<?php header ("Content-type: image/png"); $text=implode($argv," ");
$image=imageCreateFromPNG("basic.png"); $background_color =
ImageColorAllocate ($im, 100, 100, 255);
$text_color=imageColorAllocate($image,255,100,100);
$textX=(imageSX($image)-imageFontWidth(4)*strlen($text))/2;
imageString($image,5,$textX,10,$text,$text_color); imagePNG($image);
imageDestroy($image); ?> This is only a small modification of the
example given in the manual, but the $text_color is always white. This
works for JPEG, but the quality suffers, and my build of PHP doesn't support
GIF's.
