Java FFMPEG在将tiff图片转换为png时反转颜色

我们需要将数千张tiff图片转换为png。为了实现这一点，我们使用FFMPEG。我们最近注意到，对于极少数转换的文件（png），颜色是颠倒的：输入tiff文件全是黑白的（黑色背景的技术图形），输出png文件是黑白的（图形变为白色背景变为黑色）。当然我们不想这样，我们需要颜色保持不变

下面是我们正在使用的命令：

ffmpeg -y -v warning -i in_file.tif out_file.png

我们已经在这些文件上测试了“否定”参数，并且正确地转换了图片。但我们无法将此参数应用于所有输入tiff文件。 以下是带有否定参数的命令：

ffmpeg -y -v verbose -i input.tif -vf negate output.png

我们正在使用的Java代码：

            String ffmpegPath="/Users/user11/ffmpeg//ffmpeg";
            List<String> commandArgs = new ArrayList<String>();
            commandArgs.add(ffmpegPath);
            //overwrite output file if it exists
            commandArgs.add("-y");      
            commandArgs.add("-v");
            commandArgs.add("verbose");
            //set input file 
            commandArgs.add("-i"); 
            commandArgs.add(picture.getAbsolutePath());
            commandArgs.add(dest.getAbsolutePath());
            
            String cmd = "";
            for(String cmdArg : commandArgs) {
                cmd += cmdArg + " ";
            }

有没有办法识别将被转换为具有反转颜色的png的tiff文件？这样我们就可以知道“否定”参数必须应用于哪些文件

是否还有其他FFMPEG参数可以使用

在过去的几天里，这个问题一直让我们抓狂。任何帮助都将不胜感激。 谢谢

Tif图片示例

---

似乎是一个坏文件

ImageMagick

convert

也不喜欢输入。建议使用

tiffset

设置光度学解释标记：

tiffset-s 262 0 input.tif

---

现在，使用

ffmpeg

进行转换应该可以正常工作。

显示第一个ffmpeg命令的完整日志。提供一个指向有问题的TIFF文件的链接。您好，Mounia，请在代码括号中添加命令，以获得更好的阅读体验。欢迎来到SO:）非常感谢您的干预。问题中增加了其他信息。如果您能帮助我们检测负责将颜色从tif转换为png的参数，我们将不胜感激。
