What code are you using; php?

If so I assume you have #00ff345 in a variable something like $colour_varible='#00ff345'; so you could:

Code: Select all

$colour_varible='#00ff345';
$variable = "'$colour_varible'";

Then use $variable in your code.

I would have thought it was OK to have the colour name between ' ' as well but you would need to test that.

If you use hex or rgb values in IM, you need to reference them with quotes. But if you use variables to hold them then you need to use double quotes so that the variable can be parsed.

convert -size 100x100 xc:"#FF0000" ....

or

color="#FF0000"
convert -size 100x100 xc:"$color" ....

In PHP you need to be careful about nested quotes also.

thanks a lot for your reply guyz ..... here is the code iam using...

Code: Select all

<?php
if (isset($_POST['fill']) && isset($_POST['label']) && isset($_POST['pointsize'])) {
$cmd =" -background NONE -pointsize ". $_POST['pointsize'] ." -font Times-Roman -fill ". $_POST['fill'] . " ".
" -strokewidth 1 -stroke black label:\" ".$_POST['label'] . "\" ";

exec("convert $cmd 1.png");
echo "<img src='1.png'>";
}
else{
echo "ERROR";
}
?>

we can get output from any color picker in the form of #ff001236 ... but i need the out put in the form of '#ff001236' ...so that it can be accepted by imagemagick.... any idea guyzzzzz????
'fill' is the color variable i have used in input form ...

I am not much of a PHP expert but try

\"$_POST['fill']\"

[sriducati]

any idea on how can we fix this problem.. is it possible to use color picker in this case (which outputs only hexa code)... if yes which is the color picker we can try ...i tried js color picker ....but no luck... please help me...
