Description

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.

Sanselan.writeImage(Sanselan.getBufferedImage(new File("in.tif")), new File("out-tif.png"), ImageFormat.IMAGE_FORMAT_PNG, null);

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.

$ convert in.tif in.png

Sanselan.writeImage(Sanselan.getBufferedImage(new File("in.png")), new File("out-png-IM.png"), ImageFormat.IMAGE_FORMAT_PNG, null);

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.
