Dear Sketchbook Pro team:

Bravo for the best painting program for iPad.

I have used it to create 45+ paintings: http://www.flickr.com/photos/dnsf/sets/72157624456861368/

The bad news:

-----------------------------------------

IMAGE CORRUPTION

Very frequently, after saving a Sketch, a corrupted image appears containing two undesired layers that are compressed into one image; a previously-created image, along with the current image. I have many examples of this that I have saved to share with you.

If the user mistakenly begins to edit this corrupted version (containing two sketches), there will be a serious break in the workflow.

-----------------------------------------

CRASHES ON SAVE

A painting is on the screen. I press the Gallery button. Dialog: Press “Don’t Save”. From that moment, it takes 24 seconds, then it crashes back to the iPad’s home screen.

Then: Power off the iPad.
Restart the iPad.

A painting is on the screen. I press the Gallery button. Dialog: Press “Don’t Save”. From that moment, it takes 22 seconds. (AFTER A RESTART OF THE IPAD, IT DOESN’T CRASH) It shows the Gallery (containing 1767 Sketches).

Tap on one Sketch in the Gallery. WITHOUT WAITING, Press Edit.
RESULT: Immediate Crash to the iPad’s home screen.

CRASHES ON EXPORT

The Gallery appears. Tap on one Sketch in the Gallery. WAIT 10 SECONDS.
Press the Export button.
The Export Menu appears.
CRASH to iPad Home screen.

As great as the program is, it is mostly unusable without serious swerving.

Thank you.

Selected two Sketches in the Gallery.

Pressed trash can icon.

Crashed to the iPad home screen.

Opened the Gallery.

Scrolled down 4 pages—very slowly.

Crashed to the iPad home screen.

Makes the program unusable.

The answer, my friends, is to have fewer than 1000 sketches in the Gallery. 
Even better to have 950 or fewer.

My Sketches were permanently trapped inside my iPad, with no way to get them out, since Sketchbook Pro would crash with nearly any action in the Gallery.

I was able to use iPhone/iPod Touch (& iPad) ::Backup Extractor:: from http://supercrazyawesome.com—which converts iTunes backups into usable Mac OS X files. After digging deep in the recovered folders, I found my .psd and .png files, which I was able to copy into separate graphics folders.

I was then able to slowly export files from the Gallery to iTunes and to the Photo Library, then delete the Sketch. One by one, I deleted more than 800 files tonight.

Batch export (manual and even automatic) capability to iTunes (.psd & .png) and, at the same time, to the Photo Library would be very useful.
