[Swftools-common] Problems with PNG placement

[Mick]

Greetings all,

I have just started using swftools 0.9.0 and am having some trouble with 
placing PNG images on the stage. I compiled the following script with swfc:

.flash filename="test_swfc.swf" version=6 fps=50 bbox=435x122
   .png img1 filename="test.png"
   .put img1
.end

When I view the generated file in a browser it seems that the first row 
and first column of pixels are duplicated and the last row and last 
column are missing. Please see the attached files to better understand 
what I mean by this. Load test.htm into a browser and look carefully at 
the two graphics. The top one has been generated with swfc.

Out of curiosity I converted test.png to swf using png2swf. This works 
perfectly and the image renders correctly within the swf. This is 
displayed as the bottom graphic in test.htm.

I also decided to extract the png from test_swfc.swf using swfextract to 
see if it had been corrupted. The extracted image was identical to the 
original confirming this was not the case.

I was hoping someone may be able to shed some light on what may be going 
wrong.

Attached files
test.png - original  image file
test.htm - markup placing test_swf.swf at top of screen and 
test_png2swf.swf below it
test_swfc.swf - swf created with swfc
test_png2swf.swf - swf created with png2swf

Many thanks,
Mick
