Layout

[WindowsNT]

This is the output when using GuidoResizePageToMusic.
How do I tell the formatter to take the entire width before breaking to next line?

Basically, I have difficulties understanding the layout mechanism. When painting on screen and when printing, I want it to take the full width.

It's quite difficult to control the layout. In your case, I suggest to use the pageFormat tag.

[WindowsNT]

Yes, but how? I'm trying settings, none of them extends the page to the right. When I enlarge the width/height, the printing becomes smaller.

[dfober]

Using the left margin (lm) parameter of \pageFormat should help to center the image, you could also set the page width (w) to a lower value. If you really want to extend the rendering width, you might achieve that with the engine settings but that's more difficult to manage.
If you send me your gmn code I can try various options.

[WindowsNT]

This one for example

{[ \barFormat<"system"> \staff<1> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<2> \staffFormat<lineThickness=0.08,color="black"> \clef<"f4"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<3> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<4> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<5> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<6> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ], [ \staff<7> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 ]}

Shows correctly

If i add one more measure

{[ \barFormat<"system"> \staff<1> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<2> \staffFormat<lineThickness=0.08,color="black"> \clef<"f4"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<3> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<4> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<5> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<6> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ], [ \staff<7> \staffFormat<lineThickness=0.08,color="black"> \clef<"g2"> \key<0> \meter<"C", autoMeasuresNum="off"> _/1 _/1 _/1 _/1 _/1 _/1 ]}

It breaks

where it could easily hold more measures. If I increase the width in the Draw description it doesn't take it, still wants to break.
However in the online version it works ... might be my render?

[dfober]

WIth \pageFormat< w=20cm, h=20cm, tm=1cm, rm=1cm, bm=1cm, lm=1cm> it's rendered on a single line on my side.
Note that height is also important since it constraints the engine on a single page (or not).
Another solution:
in the header add the system variable :
$FORCE=550;

[WindowsNT]

I managed to do it with the aid of \set<autoSystemBreak="off",autoPageBreak="off"> and \newLine
I will let you know if there are more issues on that.

Btw here is a direct link to the score editor (which auto updates when I update it), if you have Windows >= 10 you can try it.

Fine!
Sorry I can't try your app, I don't have Windows installed.
