Jagged diagonal lines
Read 588 times

I preciously submitted an article “High quality diagonal lines” and receive several responses. Thanks to all. However I am still puzzled on how to proceed using TurboCAD 19 Pro Platinum and to do this as easy as possible. Obviously TurboCAD diagonal lines are mathematically straight, but are displayed as jagged for simplicity. Can I change this representation right in TurboCAD? If not Jeff suggests saving an image as a .png and then using Setup to specify the pixel count of 3000x2400 and 7 megapixels. I do this but now what? I open this .jpg file and get a picture but still with the jagged lines.

My thought/opinion is that it is just the limitation of using a screen-- that is composed of pixels in a grid-like fashion-- to display an angled Line.

As I recall, you wanted to insert the images into a Word document.  A printed diagonal line will look smooth at 300 lines per inch (600 pixels per inch).  In fact, it will look pretty smooth at only 200 lines per inch, but I like a bit of overkill.

At that density, your 3000x2400 image should cover 5" x 4" and look very good.
