Deep brain stimulation (DBS)

Would You be so kind to help me?

I have an ant (Dot from The Bugs Life) on my printed matter (A6 size). Is it possible to hit the T lobe of Dot with my DBS electrode (printer)? My problem is as follows: On the second (A4 size) printed matter I have the Lion King and I want to position my DBS electrode in its F lobe. If succeed I want to print a text to Dot's 3th leg "success" and the King's right ear "done".

Do I need to subclass the QGraphicsScene or the QTextDocument?

Thanks in advance,

Peter

Hi
How do you draw it now?

Dear mrjj,

I tried to subclass QGraphicsScene parsing the xml (QDomDocument) creating the scene

The problem is Dot is pre-printed. The Lion King I am able to render. I have another printed matter containing 100x 3x3mm squares to hit.

Thank You!

@Peter-Viola said in Deep brain stimulation (DBS):

The problem is Dot is pre-printed.

What is Dot ?

So the source is some xml documents describing "something"
and you want to visualize the "something" ?

Peter Viola · 17 Oct 2017, 09:18

Sorry, I was busy.

Yes, my model is the printed matter coordinates translated (mostly simply measured by a ruler) to xml (html, JSON, MySQL, PostgreSQL, etc).
The blocks are predominantly texts, but sometimes need to draw images (logo, barcode), lines too.

The problem is
1/ QTextDocument: positioning the image(s)
2/ QGraphicsScene: fit the text to QGraphicsRectItem (maybe QFontMetrics will help)
3/ QPrinter: Mostly I can render the whole form and print it to an empty sheet, sometimes I need to fill the pre-printed matter (e.g. hit a 3x3mm square (my Dot) on the paper).

Thank You.

@Peter-Viola

Hi
is it the <rect> you are drawing?

do you need to edit it on screen or is more the printing part that is important?

Peter Viola · 17 Oct 2017, 10:20

Yes, the rect is the rectangle to draw the text in, the image's bounding rectangle, etc and yes, it would be fine to present the editables before printing.

Thank You.

@Peter-Viola
Then using QGraphicsScene seems a good choice.

About issue:
2/ QGraphicsScene: fit the text to QGraphicsRectItem

You mean make text smaller so it can be inside the Rect Area?
yes, you can use QFontMetrics to get actual size and reduce point size of font until it fits.

I'll take Your advice, thank You.
