I've not tested it yet and might not be able to for a few days but according to https://klein-hu.github.io/tips/tools/libpng/png/2018/11/07/libpng.html this might do it. It does need to know the buffer size though but that can be worked around i'm sure.   Ignore that bit lol

Code: [Select]


static void pngReadCallback(png_structp png_ptr, png_bytep data, png_size_t length)
{
ImageSource* isource = (ImageSource*)png_get_io_ptr(png_ptr);

if (isource->offset + length <= isource->size)
{
memcpy(data, isource->data + isource->offset, length);
isource->offset += length;
}
else
png_error(png_ptr, "pngReaderCallback failed");
}

FBN Development / Need awesome coder!
« Last post by dink on July 17, 2019, 12:16:58 AM »
Hi guys,
Need help from someone that is awesome at code.  Even good at code will do :) 
What's needed:  Titles and Previews images are getting insanely plentiful.  It would be nice if they could reside in a .zip file instead of a directory of 12000 titles and directory of 12000 preview images (.png)

Problem is, by default Libpng only loads png files from a file handle.
We need to be able to load a png file from a memory buffer.  In FBN source, see src/burner/image.cpp.
Google: libpng load from memory
Warning: it's a bit complex :P

we need a memory analog of the following functions - replacing "FILE *fp" with "UINT8 *buffer, INT32 buffersize"
INT32 PNGLoad(IMAGE* img, FILE* fp, INT32 nPreset);
INT32 PNGGetInfo(IMAGE* img, FILE *fp);
and
bool PNGIsImage(FILE* fp);

example prototypes:
INT32 PNGLoad(IMAGE* img, UINT8 *buffer, INT32 buffersize, INT32 nPreset);
INT32 PNGGetInfo(IMAGE* img, UINT8 *buffer, INT32 buffersize);
bool PNGIsImage(UINT8 *buffer, INT32 buffersize);

buffer points to png data memory blob, buffersize is png data size.

With this, I'd be happy to hook up the rest - unless you'd like to also :)

p.s. temp file route is NOT an option :P
p.p.s: google: libpng load from memory

best regards,

Yes, it can be done in gdb - make sure "Misc->Options->Show Debug Console" is unchecked before using gdb, as the console's stdout interfere's with gdb.  I've heard ms visual studio has a nice source level debugger, if you want to go that route.

Thanks for your reply :), last question is there a way to debug c++ code using break points ?

Hi,
I use a combination of resource hacker to test things then just use my editor to make changes to the source (app.rc, resource.h etc in burner/win32).
