Hi!

I would like to share my N900 application to you. It's name is Pen Pen SketchBook , which is designed to be a replacement of the built-in Sketch application on N900. It is a handwriting memo/sketch book for quick note taking / drawing with unlimited size of paper.

Name : PenPen Sketch Book

Description:

PenPen is a handwriting memo/sketch book for quick note taking / drawing with unlimited size of paper. It is designed to be the replacement of the built-in app "Sketch" in N900 , but more focus on quick note taking.

It is vector graphics drawing tool. A single click and drag could erase the whole stroke of drawing. Word removal is much easier than bitmap drawing tool.

- Support auto-saving. No. of clicks are minimized.
- Multiple sketch viewer

Thanks !

it should have a "Play All" button, to flip across your pages at a given speed and animate the sketches :P that would be awesome to make your own cartoon on phone

Looks promising. You should find a way to soften the lines with some kind of antialiasing, for a better look of the sketches. Xournal appears to do something in this direction, or maybe it averages the points to avoid pixelated lines.

That was my initial thought too... Like the multiple sketch viewer idea, though. I hadn't thought of that in context of a program like this.

SallyJane | # 6 | 2010-06-16, 15:11 | Report

Loving this so far.

Wishes - yes, antialiased lines.

Backdrop of notebook / graph lines if possible.

If you're taking donations to take this app further, I'm more than happy to chip in for this.

looks pretty neat. Have you thought about svg export since it does vector graphics?

SallyJane | # 8 | 2010-06-16, 16:39 | Report

The colour selector sometimes appears as just a thin column. Repeatedly flipping between the main drawing screen and the colour selector tab allows more of the colour box to render until it's completely visible after three or four taps.

*edit*

It would be nice if the app remembers pen size and colour when closed.

Still, as it is it's eminently usable

Thanks for all of your reply.

Let me summarize the current bug report and feature requests

Features that will be in next release

1) Line soften / antialiasing
Yes , I will do it.

2) Remembers pen size and colour when closed.
ok , no problem~

Features that will be in later release

1) Backdrop of notebook / graph lines.

Good idea! I have made similar stuff in other software.

But just want to clarify , do you mean to have graph lines like this one?

2) Export svg
yes, I am also interested with a svg export feature, but I need study about the format first. (e.g How to specific antialiasing in svg?)

3) The colour selector sometimes appears as just a thin column.

hmm... It seems to be the bug of Qt. As its design is quite confusing, I will rewrite a new dialog for it. By the way, there have several kind of color selector in Maemo. Do you like the design of the one used in Sketch?

Anybody may suggest a design they like before I start coding.

4) Set background color

ok , but it won't have a tool bar item, it need to set in menu.

Considering

1) "Play All" button, to flip across your pages at a given speed and animate the sketches

It is interesting, but take longer time to implement in compare with other features. It could make a slide mode like "photos" app , but you could set at given speed. Do anybody else think that it is worth and you would like to play on your N900?



SallyJane,

Great to hear that! But now I don't really need donation to take this app further. Most of the feature requests are that I also want. But I use this application to join the first Maemo Competition. Will be great if you can vote for it when the polling is started

Thx!
