I'm having a very difficult time in getting wpdfDrawJPEG to work in my C++ code. I can't seem to figure out how to get the jpeg into a buffer that will work.
Here's my code:
HANDLE temp;
long li=0L;
int buflen;
int width=506;
int height=337;
char junk[1025];
char *jpg_buffer;
unsigned long bytes_read;
jpg_buffer=malloc(width*height);
temp=CreateFile("test.jpg",GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
if(temp!=INVALID_HANDLE_VALUE)
{
SetFilePointer(temp,0L,NULL,FILE_BEGIN);
ReadFile(temp,junk,512,&bytes_read,NULL);
while(bytes_read>0L)
{
memcpy((void *)(jpg_buffer+li),junk,bytes_read);
li=li+bytes_read;
ReadFile(temp,junk,512,&bytes_read,NULL);
}
CloseHandle(temp);
buflen=(int) li;
}
wpdfDrawJPEG(pdf,50,105,506,337,506,337, (void *) jpg_buffer,buflen);
It draws nothing.
