Hi Sabine,

Converting a PDF into a PNG with Pharo is not an easy task because you must write a PDF reader.��

With Artefact, the other approach is to draw on a form instead of generating the PDF instructions. For geometrics items, It's relatively easy but the respect of paper formats and the management of fonts could be very complex.��

The difficulty is to have the same result between the PDF document and the simulated document ��written in a PNG file.��

Best regards

Olivier

See Form protocol (*Graphics-files), #writePNGFileNamed: , and PNGReadWriter.
----------------------------------------------------
| canvas |
canvas := FormCanvas extent: World extent.
World fullDrawOn: canvas.
canvas form writePNGFileNamed: 'imageOfWorld.png'
----------------------------------------------------

There are also some methods in morph (#exportAs:using: #exportAsPng), but these will ask for the filename via the file dialog.

Emne: [Pharo-users] Create png from pdf

Hi,

currently, I create pdfs with Artefact and it works fine.
For displaying previews of the pdf reports, I use�� Apache PDFBox to generate pngs from the pdfs.
This works, too.

But I would prefer to generate the pngs directly from pharo and do not call external libraries.

Stephane told me that "there is a form in a morph and it can be converted in png".

Can anyone give me a small entry point or has done similar and provide some code snippet?

Regards
Sabine
