we have just bought your product "Image2PDF" as you can see on above.
We have a problem during conversion when the page has a great percentage of black colour, the result is done in reversed color. (see attached file related this problem).
Pls urgently send us the solution how we can correctly convert the file.
We have created a new version to you, please download the new version from following URL,
you can add a -v parameter to convert your TIFF file to PDF file correctly, for example,
img2pdf.exe -v -o D:\temp4\input5.tif.pdf D:\temp4\input5.tif
-v parameter will not check the amount of black points.
