[lwip-users] makefsdata strange error with .png files

[N.Karakotas]

Hi,

 

Im using the makefsdata.pl perl script to create the html data. I was having a strange problem with .png files not showing up on the browser. After tracing the problem I noticed that the array data created by the perl script was missing 1 byte of data at the begging of the png header. For example below is part of the header bytes of the images:

Correct:

89 50 4E 47 0D 0A 1A 0A 00 00 00

Wrong:

89 50 4E 47 0A 1A 0A 00 00 00

 

If you can see byte 5 doesnt contain the 0x0d! When I inserted this to the table the image showed up correctly. I cant se why the perl script is failing on this line:

 

for($j = 0; $j < length($file); $j++) {

printf(OUTPUT "%#02x, ", unpack("C", substr($file, $j, 1)));

}

 

Im using windows. Any thoughts? Its strange that one has had this problem before.

 

Regards,

Nick
