Orientation of TGA generated by nconvert

[lzn11]

I'm using nconvert.exe to convert some images into tga format.

The info of the converted tga is like this:

Format : Truevision TARGA (Type 10)
Name : tga
Compression : Rle
Width : 256
Height : 256
Components per pixel : 3
Bits per component : 8
Depth : 24
# colors : 16777216
Color model : RGB
Bytes Per Plane : 800
Orientation : Top Left
Xdpi : Not set
Ydpi : Not set
Page(s) : 1

while a normal tga file generated by any other software is like this:

Format : Truevision TARGA (Type 10)
Name : tga
Compression : Rle
Width : 256
Height : 256
Components per pixel : 3
Bits per component : 8
Depth : 24
# colors : 16777216
Color model : RGB
Bytes Per Plane : 800
Orientation : Bottom Left
Xdpi : Not set
Ydpi : Not set
Page(s) : 1

The difference lies in the orientation, and it has caused my images to be displayed in the wrong direction.(The tga images are used by a game engine)
Is there an option to correct the orientation?

No, the origin used is always top-left

What you could do is vertically flip your pictures before you convert them into TGA files.
Apparently your game does not check the orientation.
