Hi,

I’ve never used SketchBook Pro so I’m finding a few areas of SketchBook Mobile a little tricky to work out so I have a few questions…

1) Is there a detailed manual for Sketchbook Mobile I can download? I know there’s onboard help but it doesn’t cover the topics below and who knows what else.

2) Can anyone explain how the Brushes screen and editor should be used? I get that you can change various parameters but how do you save them to particular tools? What’s the difference between the ‘Marking Menu Brushes’ and the Brush Palette?

3) Can anyone explain the supposed ‘simulated pressure sensitivity’? I haven’t seen any evidence of it. How does it work?

Thanks.

We will look into posting the in-product docs as a PDF.

The brushes page contains all the preset brushes, including the top row that represent the 4 brushes that are in the marking menu.  Which ever tool that you have active, when you tap on the Editor button on top, you can adjust the settings to that selected brush.  Whatever customizations you make to the parameters, this becomes saved and that brush stores your settings.

The simulated pressure basically gives you the variable width and opacity fall off at the beginning and end of strokes.  If you pick the default pencil and quickly drop a series of strokes, you will see that they fade at the tip.  You will notice that velocity of your stroke effects the amount of drop off.  In the Brush Editor, the Min and Max values for size and opacity drive this… so if your Min value is 2 pixels and max is 8, the synthetic pressure will apply this range to the ends of strokes based on the speed/intensity of your strokes.

Hope this helps a bit.

Hi,

Yes, that did help, thanks.

If by ‘in product docs’ you mean the help text that is currently available in the app, then that’s not really what I meant. There seems to be an assumption that users of this app will already be familiar with the desktop application (SketchBook Pro, I believe it’s called) and the help is largely written based on that premise. I say that as several parts of the app aren’t explained such as the tools menu (is that what you’re calling the ‘marking menu’?), the tools themselves (I’ve just learned the fill tool, for example, fills until it reaches a border rather than filling the entire layer as I’d expect from other iPhone painting apps), the brushes page and its workings, editing brushes etc. I’d suggest the assumption should be that the vast majority of users of the app won’t be familiar with the desktop version and so the workings should be explained on that basis. Having a detailed PDF manual written in that way would be very handy with, perhaps, a link to it within the app.

My assumption when I saw the brushes page (hope that’s the right term) was that I’d be able to tap and drag a favourite brush type tool (for example) onto the top brush icon so whenever I select the brush in the main circular tools menu, my selection would appear. It seems I’m wrong from what you’ve said so I’m still puzzled why it works the way it does and how best I should use it. I feel I’m missing something here.

As for the simulated pressure, I have to say I’m pretty unimpressed with that although, admittedly, I need to try it more to see if there’s any benefit. The relationship between this and the brush settings also needs to be fully explained (with examples) in a manual.

On my 1st gen’ iPod Touch, I’m finding it runs fairly slowly (despite the limited layers and low res’) forcing me to slow down my strokes so it can keep up. Does that make a difference to how it works? I’m wondering if that has an adverse affect on the simulated pressure thing - you do suggest stroke velocity plays a part. Curious to know what you mean by ‘intensity’ of a stoke too.

Interesting app with some nice touches (love the double taps in the corners) and potentially useful but difficult to use fully with the nagging feeling I don’t understand how it’s meant to work in several areas.

someone…

Please help.....

I have the same issue. I have the 1st gen itouch and it is painfully slow. (lag time) the app is almost useless since is has to catch up to my finger stroke. Is there anything I can do to make it run faster....besides buying the 3GS?????

Also, I too would be interested in a manuel or overview/how-to guide, rather than a tutorial.

Hope you can get back to me. :-)

Thanks,

I think there is no way to make it faster. On my 2gen ipod touch it does sometimes lag, too. You could try to restart your touch, maybe this helps.

@cheungc: Is there any plan to remove the auto antialising of the canvas? Maybe this would remove the lags.
