Hi,
I'd like to suggest a few ideas. These are not related to your issue's solution, but they might be tips you have overlooked (or not).
You can achieve the same number-indexed png filenames with pngwriter_rename(), just cast the iteration variable i to an unsigned long int, and use it as the argument for pngwriter_rename(). The .png extension will be added automatically.
You don't need to readfromfile() inside the loop, though perhaps you were planning on reading from different files later on?
Unless you specifically need the UTF-8 plot_text function, you might want to use the plain one. No specific reason for this hint, really.
close() and write_png() are in fact identical. Just different names for mnemonic reasons.
I hope these tips are useful.

// xbnbt_test_png.cpp //
#include <pngwriter.h>
void test () { pngwriter image( 1, 1, 0.0, "out.png" ); image.setcompressionlevel( 0 ); char cName[255]; for( int i = 0; i != 1000; i++ ) { sprintf( cName, "%d.png", i );
std::cout << "Writing: " << cName;
image.pngwriter_rename( cName );
image.readfromfile( "burro.png" );
image.plot_text_utf8( "arial.ttf", 14 ,4 ,4, 0.0, cName, 0.0, 0.0, 0.0 );
image.write_png(); std::cout << " Done.\n"; } image.close( ); } int main() { test();
system("PAUSE"); }
For some reason it crashes at image 508.
Permissions are fine.
Not sure how to send a backtrace but I will find out.
