Working around missing QuickTime support?

Hello?

Nothing very useful yet.

Paintlib requires C++ Exception Handling - something that I'm trying to avoid altogether with C4D plugins and much too big to edit to remove them.

libPNG is C and has issues with C++ (but I am searching for a C++ wrapper - hopefully without exception handling). Even with that, PICT support would be unavailable.

I have found nothing (besides PaintLib) that supports PICT reading. ImageMagick was a possibility, but it is really an application with an API - and requires installation and configuration to boot. I'm not doing ImageMagick tech support ontop of that for my plugins!

All that I want is plain C/C++ code to read PNG and PICT into a bitmap that can be somehow copy-converted into Cinema 4D BaseBitmap memory.

Help!

Sorry, absolutely no clue. This is definetly not my metier. My very guess would have been Paintlib too, but I don´t have any experience with it.

No help, but a sign of life at least!

Unfortunately, Paintlib is a mess with missing source/header files and other problems.

For PNG support, libpng is it. Wow! It loads PNGs (even with alpha channels) 5+ times faster than the QuickTime support used by Cinema 4D. I am converting all of my version support to use it instead.

If anyone needs such support for 64-bit Windows (or generally in Cinema 4D), I'd be happy to forward my source.

Thanks,

One thing to note is that libpng doesn't currently come with VS2005, CodeWarrior, or Xcode projects. There is a VS2003 project, but I found it clumsy in conversion and built my own from the zlib static lib project used by the plugin.

Even then, I had to fiddle with this project's build settings to remove 'unresolved external symbol' errors related to libpng during link with my plugin - about three hours of frustration before it started working.

Still dealing with a similar situation in Xcode - unresolved external links which seem to be functions that aren't being included by any of the billion #defines. This will require some detective work.

Hey Robert,

this is exactly what i was looking for, since all 64-bit/vista users cant run my plugin anymore, it would be great if you could share that piece of code.

thanks in advance!

Are you looking to use libpng for PNG image file support in these Windows versions?

You can download a zip containing the following from the link below:

- 64-bit Windows static libs built with VS2005
- Headers for zlib and libpng (libpng requires zlib for compression/decompression)
- Readme.txt to exemplify use of the PngLoad class

Of course, you can download the latest zlib and libpng if you need to build the static libs yourself. It is a bit tricky to set up the VS2005 project (as none accompanies these libs).

Can you try the link again and let me know if it works? I just upgraded NAV and, brilliant, it didn't retain any of my previous settings. I can access everything, but can't test offsite. Working on getting the entire server back online. Hopefully the web server is accessible now.
