Hi.

How can I save multi-page TIFF?

First, I read the multi-page TIFF successfully.
And Process loaded bitmap on each page, then save it another multi-page TIFF.

But can't save multi-page TIFF.
My source code is below...
What is my mistake in save code(Line #27).

Code:


L_INT ret;
LFile r_file;
FILEINFO r_fileinfo;
memset(&r_fileinfo, 0, sizeof(FILEINFO));

r_file.SetFileName(string_to_TCHAR(input_file_path.string()));
ret = r_file.GetInfo(&r_fileinfo, sizeof(FILEINFO));
if (ret == SUCCESS)
{
	std::cout << "Name : " << input_file_path.filename().string() << std::endl;

	std::cout << "Format : " << r_fileinfo.Format << std::endl;
	std::cout << "Page count : " << r_fileinfo.TotalPages << std::endl;

	for (int page_idx = 0; page_idx < r_fileinfo.TotalPages; page_idx++)
	{
		LBitmapBase bitmap;
		ret = bitmap.Load(string_to_TCHAR(input_file_path.string()), 0, ORDER_BGRORGRAY, page_idx, NULL);
		std::cout << "Load ret : " << ret << std::endl;

		std::cout << "Page : " << page_idx << std::endl;
		std::cout << "BPP : " << bitmap.GetBitsPerPixel() << std::endl;
		std::cout << "Order : " << bitmap.GetColorOrder() << std::endl;

		// TODO Process...

		ret = bitmap.Save(string_to_TCHAR(output_file_path.string()), r_fileinfo.Format, 0, get_quailty_factor(r_fileinfo.Format), page_idx, 0);
		std::cout << "Save ret : " << ret << std::endl;
	}
}

Thanks.

I solved a issue myself...

My mistake is page index number.

The page index must start at 1. But my code is start at 0.

I change the for-loop to "for (int page_idx = 1; page_idx <= r_fileinfo.TotalPages; page_idx++)", then solved it.

Thanks.
