Weidr Output image with the esri tile index file -- GDALTINDEX

[Zhonghai Wang]

HI guys,

I've created a tile index file with the GDALTINDEX utility for my small
raster jpeg images, all things work well, but the end output jpeg image with
MapServer is a little weird, there are some white grid lines on the output
image. I don't know if there are some blank areas between the tile images
when creating the tile index file, or the tile index grid are drawn by
MapServer on the output jpeg image.

attached is a small example output jpeg image.

any clues are welcome.

Best Regards

Zhongahi
