Description:
------------
If you "imagesettile" on an image created through "imagecreate" then use "imagefill" and "IMG_COLOR_TILED" as color as explained in the documentation, it's fine. But if the basic image is not created on the fly, eg. it is imported through "imagecreatefromXXX" then your "tile image" won't be apply on that image :-)
NB: any version of GD, even the bundled one.
See an example of NOT working code below.
Thanx
Reproduce code:
---------------
<?php
header ("Content-type: image/png");
$im = imagecreatefrompng("basic.png"); /* 200 x 200 */
$im = imagecreatefrompng("tile.png"); /* 10 x 10 */
imagesettile($im, $tily);
imagefill($im,110,90,IMG_COLOR_TILED);
imagepng($im);
imagedestroy($im);
?>
Expected result:
----------------
basic.png (a map in fact) tiled on a delimited area (a country).
Actual result:
--------------
Just the basic image (basic.png), not tiled at all.

Here's my test script:
<?php
header ("Content-type: image/png");
$im = imagecreatefrompng("basic.png"); /* 200 x 200 */
$tile = imagecreatefrompng("tile.png"); /* 10 x 10 */
imagesettile($im, $tile);
// imagefilledpolygon ($im, array(0,0,200,0,200,200,0,200), 4, IMG_COLOR_TILED); // Works
// imagefilledrectangle ($im, 10,10,190,190, IMG_COLOR_TILED); // Works
imagefill($im,10,10,IMG_COLOR_TILED); // Does not work?
imagepng($im);
?>
But when I used imagefill(), it only draw one line in the top with the tile and the tile image was somewhat scaled down..(I'm not sure if it's supposed to work like this? :)
# file tile.png
tile.png: PNG image data, 10 x 10, 8-bit/color RGB, non-interlaced
# file basic.png
basic.png: PNG image data, 200 x 200, 8-bit/color RGB, non-interlaced

Well, It should work with imagefill() just like it does with other functions (imagefilledrectangle...) I mean, just filling with the tile, not only drawing a 'kind' of line or just doing nothing. Someone should check GD. If this problem doesn't occur with the C version itself, or with a Perl interface, then it's a PHP bug, otherwise it's a GD bug.

It's a GD bug, not a PHP one, 'cause I've got the same wrong result in perl :(((

I cannot reproduce it here, using the RC or the head. Do you have a link with the 2 used images? thanks pierre

Hi Pierre, Here are two images I've got the bug with: http://www.bantu.ovh.org/images/basic.png http://www.bantu.ovh.org/images/tile.png sometimes my host is down :(, so try later in case And the code is: <?php header ("Content-type: image/png"); $im = imagecreatefrompng("basic.png"); /* 150 x 150 */ $tily = imagecreatefrompng("tile.png"); /* 10 x 10 */ imagesettile($im, $tily); imagefill($im,100,75,IMG_COLOR_TILED); imagepng($im); imagedestroy($im); ?> I just get a dotted line (y=75) Waiting for better news. Thanks Jack
