<function>imagecolortransparent</function> sets the transparent
|
|
color in the <parameter>image</parameter> image to
|
|
<parameter>color</parameter>. <parameter>image</parameter> is the
|
|
image identifier returned by <function>imagecreatetruecolor</function> and
|
|
<parameter>color</parameter> is a color identifier returned by
|
|
<function>imagecolorallocate</function>.

<para>
|
|
The transparent color is a property of the image, transparency is not a
|
|
property of the color. Once you have set a color to be the transparent
|
|
color, any regions of the image in that color that were drawn previously
|
|
will be transparent.

</para>

|
|
<para>
|
|
The identifier of the new (or current, if none is specified)
|
|
transparent color is returned.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
Transparency is copied only with <function>imagecopymerge</function> and
|
|
true color images, not with <function>imagecopy</function> or pallete images.
