I spend more then two hour to find a function that can fill a pattern or file as background instead of color. but i can't find. so i develop the following function. i though this function will save time who need it...



Function will get four parameter

1. Main Image Identifier

2. Pattern Image Identifier

3. Final Image Width

4. Final Image Height



If you set final image width or height is less then main image width or height then you may get wrong result



<?php



function fill_with_patternfile($p_main_im, $p_patternfile_im, $p_width, $p_height){

    $pimiX=$p_patternfile_im;

    $pw=imagesx($pimiX);

    $ph=imagesy($pimiX);

    $targetImageIdentifier=imagecreatetruecolor($p_width,$p_height);

    if($pw<$p_width && $ph<$p_height){

        for($pX=0;$pX<$p_width;$pX+=$pw){

            for($pY=0;$pY<$p_height;$pY+=$ph){

                imagecopy($targetImageIdentifier,$pimiX,$pX,$pY,0,0,$pw,$ph);

            }

        }

    }else imagecopy($targetImageIdentifier,$pimiX,0,0,0,0,$pw,$ph);

    $w=imagesx($p_main_im);

    $h=imagesy($p_main_im);

    $nX=0;

    if($w<$p_width) $nX=intval(($p_width-$w)/2);

    $nY=0;

    if($h<$p_height) $nY=intval(($p_height-$h)/2);

    imagecopy($targetImageIdentifier,$p_main_im,$nX,$nY,0,0,$w,$h);

    return $targetImageIdentifier;

}

//    If you want to use a gif or png file as

//    pattern file you need to change function below :)

$pattern_im=imagecreatefromjpeg('logo.jpg');

//    If you want to use a gif or png file as

//    main file you need to change function below :)

$main_im=imagecreatefromjpeg('r2.jpg');

//    call the function width 500 and height 500

//    if your width and height is less then main images

//    width and height then you can't understand any change!

$final=fill_with_patternfile($main_im, $pattern_im, 500, 500);

//    view the image and destroy all instance

header('Content-type: image/jpeg');

imagejpeg($final);

imagedestroy($final);

imagedestroy($main_im);

imagedestroy($pattern_im);

exit();

Use imageSaveAlpha($image, true); to preserve transparency.

Didn't see this documented, although it's outlined in imagefilledrectangle, it wasn't quite so obvious to me at first



imageSetTile($image,$imageBack);

imagefill($image,0,0,IMG_COLOR_TILED);



Will fill an image with a texture (this is great as I'm building a logo/template creator)

This function, cannot deal with transparencies. 

So you need to use imagecolorallocate instead of imagecolorallocatealpha.

Thus, be careful with color variables that allready set with imageallocatecoloralpha because this can slow-down or hang-up your system.

For new images, you must allocate a color before this function will work.

Actually, it can handle pre-transparent images. To remove it you need to do something like:

   imagecolortransparent($img, 0);

to null out the previous transparency colors. ;)

This function does not seem to work with images already been transparent. If you fill at x=0, y=0, and there are still transparent parts that you did


not reach with your fill, they change to a different color.





The ImageColorSet function seems to be the solution, but i can't work with transparancy.
