With stdout(1) system outputs a lot of symbols without sense.
For example this following code from Template::Plugin::GD::Image documentation
that I inserted in my table row:
<tr><td>
[% FILTER null;
USE im = GD.Image(100,100);
# allocate some colors
black = im.colorAllocate(0, 0, 0);
red = im.colorAllocate(255,0, 0);
blue = im.colorAllocate(0, 0, 255);
# Draw a blue oval
im.arc(50,50,95,75,0,360,blue);
# And fill it with red
im.fill(50,50,red);
# Output binary image in PNG format
im.png | stdout(1);
END;
-%]
outputs binary symbols without sense.
How can solve this problem?
