so the result is like I display the lines in the reverse order (from bottom to top, and not from top to bottom)
Is the framework you're using based on Windows bitmaps? For Windows bitmaps with positive height (structure member BITMAPINFOHEADER::bihHeight > 0) the scanline order is bottom to top.
i know this (I did the windows port of that framework). It is a cross platform one and the other images (png, jpeg, etc...) are correctly displayed
Perhaps it's sufficient, if you set the height of the image in the framework to the negative value of the real height (length in terms of TIFF).
