Description

Use your iPad as a lightbox for tracing! I have created this simple app to transfer digitally created sketches to drawing paper - it runs on any iPad including the first generation (iOS 5.1.1).

Import a picture from your saved photos, or paste an image from the clipboard. Scale, position, and rotate (90 degree increments - use the toolbar button) to your taste.

With an additional in-app purchase, you can use filters to enhance the image for easier tracing. You can test drive this feature a few times for free.

If all you need is a big white light (for tracing from another piece of paper), press the white square on the toolbar instead.

Hit the "lock" icon to set the screen to maximum brightness and pin the picture down - subsequent touch events are ignored. You can now place a sheet of paper onto the display and trace the image, without accidentally moving it around.

Note: You also should disable the 4- and 5-finger multitasking gestures in the general section of your device settings.

To re-enable the user interface, deactivate the app with the device's home button, then activate it again.

What’s New

Version 2.0

This app has been updated by Apple to display the Apple Watch app icon.

New filter panel for enhancing the image used for tracing: brightness, saturation, contrast, and threshold. This is an in-app purchase, but you can try it out for free.
Also added a help page and fixed a few UI glitches.

Great, but please continue to develop!!

Thank you very much for creating this app. I’m using it for university. I love the “lock” feature so I can use as a traditional light box. However— Please develop a feature for unlocking the Lightbox mode so I don’t have to close the app and reopen it in order to use other features of the app. Perhaps include a tap or knock feature to unlock the screen? For instance, tap three times to unlock the mode. Or give users a feature to customize their own rhythm to unlock the mode. Thank you very much.

Great

Excellent simple lightbox for artist or others who need to trace items. It’s intuitive and lets you grab an item from your files clip them to the lightbox and then you can trace them. Unlike when you try to trace from your photos the app allows you to resize and hold the pic in place so it does not jump around if your hand touches the screen. There is one issue - there is a lock feature so your picture does not slide around. This is a great feature. But once you engage the lock you have to close the app to go back to blank screen. It would be great to not have to leave the app and just move on to the next project.

Always sideways, but good locking function

Unless it's a screenshot or an image I saved in the net....

All photos I've taken myself are always sideways. Not even because I took the picture with my device sideways or anything. It just always puts it sideways and stretches the image to fit the screen. Making the "turn 90 degrees" and "scale" functions absolutely useless, because it's already distorted the image to fit the screen. All my upright photos are being turned sideways and stretched upwards.

If you want a Lightbox for images you download, I think it'll be worth it for the locking screen function. Otherwise, if you ever hope to use your own photos, you're better off finding something else.
