Details - The bug reported in the bug #32 has not been fixed properly. The problem is when the destination image is true colour and tile is palette based. im->transparent in the tile image is just the palette index, and we can not compare with the 31 bit true colour.

This is one way to fix the problem:
<code>
-----[939 changed to 939]-----
<       p = gdImageGetTrueColorPixel (im->tile, srcx, srcy);
---
>       p = gdImageGetPixel (im->tile, srcx, srcy);
-----[941 changed to 941]-----
<             gdImageSetPixel (im, x, y, p);
---
>             gdImageSetPixel (im, x, y, gdImageGetTrueColorPixel (im->tile, srcx, srcy));
</code>
