pdf export errors

Core Library Questions

Hello.

I am trying to do some simple drawings and export them as pdfs so I can import them to a laser cutter. However I am getting two types of error and having looked through the forum cant find a simple answers:
Error 1 -

When I use "import processing.pdf.*;" at the start of the sketch I get :

More than one Library is competing for this sketch...
pdf (part of processing)

Extra Librarys need to be removed before ths sketch can be used.

By which I infer that the PDF library is now part of the central core of Processing so I do need this line at the start... OK so...

Error 2 -

When I remove the offending line I get: the following tirade which I believe means - put it back

Exception in thread "Animation Thread" java.lang.RuntimeException: You need to use "Import Library" to add processing.pdf.PGraphicsPDF to your sketch.
    at processing.core.PApplet.makeGraphics(PApplet.java:1836)
    at processing.core.PApplet.createGraphics(PApplet.java:1772)

    at processing.core.PApplet.run(PApplet.java:2140)
    at java.lang.Thread.run(Thread.java:680)

I am confused. I assume I am doing this wrong? but the reference say do it this way.?

Any help would be much appreciated.

Regards

" By which I infer that the PDF library is now part of the central core of Processing so I do need this line at the start"
It always was part of the core libraries of Processing (at least for several years).
But being a core library, the import is still necessary.

I never saw this message...
Have you named your sketch pdf or PDF or similar?

Hi PhiLho,

Thank you for responding.

Your first statement clarifies my understanding of the relationship between the .pdf export library and Processing. I thought it had been brought 'inside' rather than being something that still needs to be 'imported'.

If its the .pde that you asking about here its just named PdfExortEx1.pde but - as an example of the problems I am having with this issue... I tried just copying one of the Processing Reference examples and pasting it into a sketch in processing 2.0.8 on a Mac running 10.5.8.

This is the Reference example -

start --

import processing.pdf.*;

void setup() {
size(400, 400);
beginRecord(PDF, "everything.pdf");
}

void draw() {
ellipse(mouseX, mouseY, 10, 10);
}

void mousePressed() {
endRecord();
exit();
}

end --

If I run the sketch then I get this error (I have pasted a screen grab of the error dialog) which repeats as listed above and have included the text in case the image doesn't come though:-

start --
More than one library is competing for this sketch.
pdf(part of Processing)
pdf(/Users/Davidlk?Documnets/Processing/libraries/pdf)
Extra libraries need to be removed before this sketch can be used.
-- end

dialog --

-- end

Any ideas?

Many thanks for looking at this.

Regards

Aha! It is must better with full message!
It looks like you have a PDF library in your sketchbook, as an additional library.
Perhaps try and remove (or move elsewhere) the pdf folder in the /Users/Davidlk?Documnets/Processing/libraries/ path.

Hi PhiLho,

Ah Ha! That seemed to work. I should have looked more closely at the dialog. I can now create .pdf exports of a recorded sequence.

I'm not quite sure how that other library got there though...

Thank you for your help -

Regards

David
