[RESOLVED] imagecopymerge question

[baffled_in_UK]

Hello,

I am creating copyright messages on the fly, however no matter what opacity I set the PNG-8 to it always displays too dark. I have 3 separate files depending on whether the image to be displayed is light, medium or dark. The code is here :

$env = $_SERVER['DOCUMENT_ROOT']; 
$abpath1 = $env . "output/$gallery_img";
if ($gallery_contrast == "L") { $abpath2 = $env . "copyright4.png"; }
if ($gallery_contrast == "M") { $abpath2 = $env . "copyright5.png"; }
if ($gallery_contrast == "D") { $abpath2 = $env . "copyright6.png"; }

$image = $abpath1; 
list($width, $height) = getimagesize($image);
$background = imagecreatefromjpeg($image); 
$insert = imagecreatefrompng($abpath2); $dest_x = ( $width / 2 ) - ( 225 / 2 ); $dest_y = ( $height / 2 ) - ( 250 / 2 ); 
imagecolortransparent($insert,imagecolorat($insert,0,0));
$insert_x = imagesx($insert); 
$insert_y = imagesy($insert); 
imagecopymerge($background,$insert,$dest_x,$dest_y,0,0,$insert_x,$insert_y,35); 
imagepng($background,"",50); 

All the "merged" images seem to be ignoring the opacity in the copyright images and although it looks fine on the "light" images, on the dark ones the copyright text is too "in your face". Can anyone give me any pointers?

Thanks

just as you use different images for light/medium/dark, you should probably use different alpha values too.

Do you mean within the .png files or is it a parameter on one of the image commands?

I would recommend some experimentation with either the contents of the png files - there may be some other image which works better for the dark files.

OR you can alter the last argument to [man]imagecopymerge[/man]. You currently have it set at a fixed value of 35. why not lower for dark images?

Spot on. I changed it to 15 and it's perfect. Thank you.
