Are you sure this was the same? Font.Resolution had a completely
different description:
--------------
STATIC PROPERTY Resolution AS Integer
Returns or sets the resolution used for transforming font size from
points to screen pixel sizes. By default, font size is based on a 96 DPI
resolution.
Gambas use this property so that a given font size will always display
the same whatever the real screen resolution is.
--------------
In the printing engine I programmed in Gambas1, the only chance to get
pictures/images (such as firm logo etc.) printed correctly was to
compute a graphical ratio like this:
'before starting to print, get graphical ratio
grafikRatio = Desktop.Resolution / Font.Resolution
'then start printing, and when it's an image,
'compute the printing ratio for it and calculate
'the stretching values in percent (as they are given
'in the printing form)
bild = image.Load(datei$)
druckRatio = Printer.Resolution / Desktop.Resolution * grafikRatio
breite = bild.Width
hoehe = bild.Height
breite = (breite / 100 * prozent) * druckRatio
hoehe = (hoehe / 100 * prozent) * druckRatio
Draw.Image(bild.Stretch(breite, hoehe), x1, y1)
Don't ask me about details, it's been a long time ago, but it used to
run this way and had cost me a lot of brain pain at that time to develop
:-) I vaguely remember that otherwise the images turned out way too
small or too large.
Now fyi, in Gambas2 I just replaced Font.Resolution by "96", and it runs
as expected. The basic question now is, what does printing have to do
with desktop resolution, and is there an easier way to achieve this in
Gambas2?
