I don't agree into the closed classification of the
"[ 1582562 ] Scalable output " subject.
I apologize not to be clear into my text, fact which
explains that this subject could be confused with a
which is [ 1161335 ] Implementation of vector graphics
export. Subjects are connected but not included just
overlayed a little.
I Explain :
The scalable output format allows to easily re-use the
output into different tools to obtain scalable output
documents. For example
1- acrobaét reader offer option to print to fit the
printer size with an output.
2- if you print to a ps driver (which accepts the full
size of the current ganttproject draw) you can define
into ps driver, the scale option of your output, but it
is the lonely case.
3- If you use other drawing tools which accept vector
graphics you can resize the part of your which is
imported the GanttProject draw if the output is into a
For the moment the lonely way (but which functions
perfectly) is to print with a largeprinter driver in PS3.
My object was different :
- add feature to GanttProject to defined for print and
preview the document size.
Actually the preview of prints allows as the main
screen to reduce or extend the graphic part and change
limits dates, but don't allow to enhance or reduce the
So if you use a A4 printer without any other tool you
will obtain a multiple pages document with any
possibility to change the scale.
In the same way if you print with a "Acrobat distiller"
you will obtain a maximum document size of A3 so the
printed document for a project of 150 lines a maminum
of three pages which are imposible to consult on screen
any size it is (23") because it is into separate pages.
My momentaneous solution is to print to a PS3 driver
for large outputs and convert to pdf via ghostgum and
the n use acrobat reader to print it. The document size
seen by Acrobat is the original fixed size of GanttProject.
With other scalable outputs (pdf, svg ...) you can
easily resize them (keeping image definition because of
the vector format) but using drawing tools.
But the primarly size is defined as fixed size by
But I think more generally cases.
If GanttProject could scale the draw for printing
manual or azutomaticac as acrobat made it should be
easy to fit easily a document for A2,A1,A0 indepedently
of the device. If the output is scalable because in
vectorial format it could be easily resized as defined
As I test a solution (PS3 large size print), it is
possible to print till 200 task planning into vertical A0.
After, the separation into pages could repeat (option)
the calendar with depend line information recall (I can
tell you about because I had to manage and draw more
than 10,000 task programs)
So if I summarize the need is to be able to say to
GanttProject set the scale of the planning to fit for
example A2 format.
So this A2 output is printed on raster printer it will
,if margin are well defined be printed into 4 A4 pages,
Another use is to scale enhanced to print directly to
large format printers (raster, not necessary able to
PS3 or HPGL2) to be able to show and comment planning
to several persons with a great font characters
This feature can be delayed into the development
program because of the solution existence : PS3 driver
+ Ghostgum + acrobat and capacity of this tools-string.
