Here is my problem:
I have some small rectangular drawing of different sizes (about 3" x 4" or 5" at 200 pixels/inch).
I want to place a simple solid black line border around the edge of the canvas.
These drawings have a white background.
I do not want white showing past the outside edge of the border.
I want the border to show with an even smooth width on all four edges of the drawing.
I want to specify the color and the width of this border.
Here is what I have unsuccessfully tried:
Using the Rectangle or the Line tool on a layer assigned for the border is a hit and mostly miss proposition.
For the Rectangle tool, once the rectangle is placed on this layer, I do not know how the adjust this rectangle. I erase the rectangle and try again. Sometime what I see is okay, but most of the time what I see is irregular and poorly positioned.
For the Line tool the lines drawn often show as a stepped line, not a single width line. I do not know how to not have these steps occur, and I of course do not want curved lines.
Can you instruct me about how I can create a simple solid black line border around the edge of the canvas?
