What’s Coming Up Next? – MacHouse Introducing Oh My Lines for Mac OS X

Mac software Oh My Lines

TOKYO (MacHouse) – Hmm… We thought we were slow this month. Maybe not… We are ready to introduce the third software title of the month. We submitted a new desktop application to Mac App Store several minutes ago. This new software submission is called Oh My Lines.

Oh My Lines is a desktop application that lets you convert a color picture into a black-and-white image with lines. You can adjust the line angle and the line width to convert a color picture into a visually-interesting B & W image.

    5. How the problem occurred : the apply don’t want to save image, the lines “Export” and “Export all” are grey and not active.
    Can you help me ?

  2. Those toolbar buttons will stay grayed out as long as one of the graphic values (brightness, contrast, line angle, line size) are invalid. If any of them is invalid, you should see text in red. I’ve just tested the application under OS X 10.9. And I don’t have any trouble. If you go to http://support.mhvt.net/ and send us a screenshot and sample pictures, I’ll be happy to help further.

  3. Thank you for your pictures, Ms. Campion. I’m not sure what the problem is that you are facing, but I’m sorry.

    After seeing your screenshot, I don’t see anything wrong with what you are doing. I’ve used your cat picture for myself. And I don’t have trouble. The following link gives you a desktop video for my workflow.

    One thing that I notice on your screenshot, though, is that your menu bar is orange, and there is an icon with 6 dots appearing to the left. And the application window is colorized as well. I don’t know what application you are using. I’ll keep looking, but I don’t have a clue for now. It sort of reminds me of Unix-like OS other than Mac OS X.

    By the way, you’ve sent your pictures to our mail address at junk913@gmail.com. I don’t have trouble for your doing so. It’s just that we use this mail address to collect and analyze spam messages. And we only check messages every one or two days.

    And that’s a very cute cat. Is she married?

    Yours truly,

    Tom Bluewater
