Hello !

I'm working about a drawing interface. The result must be the draw surface who is save into another bigger Jpg, I use PGraphics for this.

The problem is than the bigger jpg is in format A4 in 150 dpi, but when I save the new JPG he change in 2 A4 in 72 dpi.

But I want that the ending format be easy printable, without dpi's translation in photoshop (or other soft). I want than the ending files can be print without modification.

Library, function or other solution, exist for export in 150 dpi ?

thank you

.Flo.

That's the price to pay for custom output... Personally, I would just use something like ImageMagick to post-process the file, it is just a matter of changing its metadata.
