Re: [ft-devel] PDF text rendering error

I attached the TTF in your sample PDF, and

attached PNG is my rasterization result.

I think it's OK.

Your sample was not compilable. The compiler in MS Visual Studio 2008 complains like this.

Compiling...

freetypetest.c

c:\users\mps_jp\documents\2012_06\freetypetest.c(13) : warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

[snip]

It is the fundamental error, your source includes following part.

// Calculate file size int size = 14 + 40 + pitch*height; unsigned char buffer[40];

memset(buffer, 0, 40);

The declaration of the "size" and "buffer" are commented out.

Maybe you copy/paste the source code from somewhere and injected

some manual error. Similar errors are found in several parts.

Also seeing the part like

int main(int argc, char** argv){

if (argc == 1) {

printf("Usage: gcctest <path> [<start page #>] [<page count>].\n");

return 0; }

makes me feel sad.
