When drawing a simple line, how to prevent anti-aliasing and keep multiple lines in one layer

Question

I'm trying to draw multiple simple straight solid lines without anti-aliasing and without creating multiple layers for every time I change direction or make a new line. I need to use the line tool...the pencil is too erratic for the length of the line.

Answer 1

With the Line Tool active make sure the "Pixels" mode is selected and un-check "Anti-alias" in the top bar. Be aware that this is drawing pixels on a raster image layer and your lines aren't editable as vector shape layers would be.

Answer 2

I found a more direct method.

1. Create a new layer or select a raster layer of choice.
2. Open the PENCIL tool (my mistake was I had the BRUSH tool open).
3. Enter the SIZE of the line desired, and MODE to normal.
4. Create your line. The shift key will hold line horizontal, vertical or 45°.

This method is for Photoshop 7.0.

Go to Edit > Preferences > General... or press Ctrl + K then try changing the interpolation to Nearest Neighbor (preserve hard edges)
