Hi David,

I'll look into GraphicsMagick.

Thank you for telling me about this awesome function!

It works here (Ubuntu, Frescobaldi 3.0.0). I hope you get it back somehow.

Hi Karlin,

Have submitted an issue on the Github repo. Thanks.

There's 291 outstanding issues presently. Perhaps I should hop in and start
debugging some Python.

Yes, I see what you're doing now. The "scrot" method is what I would
use to produce the image that Ben posted, whereas you are lacking the
functionality illustrated within that image: ie capture of the blue
rectangle.

> Frescobaldi also allows you to automatically crop the image to the

Would this imply that you normally capture the entire music, surrounded
by white margins? Is it unsuitable to run LP so that it produces a
PNG file (rather than PDF) with   --png -dresolution=1200
(or whatever value is appropriate)?

Programs like GraphicsMagick can crop a PNG image; GM's terminology
for cropping in this manner is "trim", ie "removes any edges that are
exactly the same color as the corner pixels."

Aside: I don't know what your workflow is, but with PNG files (which
are rasters) you have to worry about resolution, whereas with a PDF
file workflow, the images are vectors and remain sharp regardless of
the magnification. There are programs like pdfcrop that crop/trim
PDFs in the same manner.

Cheers,
David.

Hi Joshua,

Hold on! I just tried again to check, and now the error occurs for me also.

Traceback (most recent call last):

File
"/Applications/Frescobaldi.app/Contents/Resources/lib/python3.5/frescobaldi_app/musicview/__init__.py",
line 312, in copyImage

File
"/Applications/Frescobaldi.app/Contents/Resources/lib/python3.5/frescobaldi_app/copy2image.py",

line 150, in readSettings

TypeError: unable to convert a QVariant of type 10 to a QMetaType of type 67

Therefore I would say this is a bug in Frescobaldi.

I am never sure where to report Frescobaldi bugs. Can somebody let me know?

Hi Joshua,

New install of F. this morning, 2.20.0 on OSX 10.3.5. Works fine. Image
capture no problem.

While this does not solve your issue, it does form evidence that it works
just fine. This install was from the DMG image provided on the release page.

Hi Joshua,

I am running this up now for you on my Mac at 10.13.5. From whence did you
obtain Frescobaldi?

If mac ports, a lot has changed, as the version of Darwin underneath OSX
has changed considerably - new major rev. number. You would need to
reinstall it from a clean beginning.

I'm not an OSX person, but isn't there a feature where you can
just take a screenshot of the display from within the system
itself? I'd be surprised if that didn't exist. (think: printscreen
/

https://www.itg.ias.edu/content/keyboard-shortcuts-capture-screen-shot-mac-os-x
)

Once you had that screenshot, you could at least use a software to
crop, annotate, etc. - as a workaround right?

i..e on Windows, Irfanview, Greenshot, etc.



I'm very sorry you're stuck in this position with your OSX system. All I 
can suggest is to maybe try resetting your preferences in Frescobaldi 
and see if that works.

(ala https://github.com/wbsoft/frescobaldi/issues/814)

Might get lucky.

Otherwise, if you're really stuck, maybe creating a virtualbox Linux 
install would be best to get these screenshots to work. If you truly 
need the built-in Frescobaldi function, and time is crucial to this 
project, I don't know what else would be beneficial in the short term.


Hope that helps.

The MacOS equivalent would be Grab.  You can find it in the Utilities 
folder of your applications and it allows you to take capture the full 
screen, particular windows, or a rectangular selection.  It saves to 
tiff format, but that can be converted to png with Preview (or a whole 
host of other image manipulation programs).

Re: Cannot PNG capture with Frescobaldi macOS 10.13.5

[Joshua Nichols]

I think you miss it because the functionality is within Frescobaldi itself.
It's run in the preview, and it allows me to customize aliasing,
resolution, etc, and it captures to png, as Ben pointed out.

Any form of screen capture would be insufficient.

Frescobaldi also allows you to automatically crop the image to the
boundaries of the music, which is primarily why I use it.

I thought he was talking about the function within Frescobaldi, which is

I think the system-style approach should work as a workaround like you

HI Joshua,

As per normal, it would be most helpful if you provide version information
for the operating system and Frescobaldi, and any other Pythons you have
that may be involved. Otherwise it's a bit hard for people to help and/or
replicate.
