> I found 2 bugs.
> I have tif file in.tif.
> 1. After convert it to png (bmp, tga, etc) by Sanselan it getting horizontal lines.
> {code}
> Sanselan.writeImage(Sanselan.getBufferedImage(new File("in.tif")), new File("out-tif.png"), ImageFormat.IMAGE_FORMAT_PNG, null);
> {code}
> gwenview, eog, kolourpaint, gimp, etc show in.tif without lines and out.png with lines.
> For example 1st line at ~860 points from top and in full width of picture.
> 2. After convert it to png by convert utility from ImageMagic, and then convert it to png (bmp, tga, etc) by Sanselan it became "gray" - all white pixels become gray.
> {code}$ convert in.tif in.png{code}
> {code}
> Sanselan.writeImage(Sanselan.getBufferedImage(new File("in.png")), new File("out-png-IM.png"), ImageFormat.IMAGE_FORMAT_PNG, null);
> {code}
> gwenview, eog, kolourpaint, gimp, etc show in.png as black and white, but out-png-IM.png as black and gray.
> I'll attach all 4 files.
