Hi Guys,
I'm a long time user of Gnumeric and just got a 13" Macbook Retina (to run
GNU/Linux on). In case anyone is unfamiliar, this computer has a 2560x1600
screen with a 13" diagonal so the pixel density is around double the usual.
This makes unmodified programs appear tiny. I think high DPI displays will
become more common on the desktop soon with the rise of 4K displays.
To my delight, Gnumeric already has a DPI setting which defaults to 96. I
doubled it to 192 and most things look good however the text appearing in cells
is not effected and remains tiny compared to the increased size of the cells.
I've come up with a simple patch (below) that also scales the text displayed in
cells and in the item edit area.
Since I am completely unfamiliar with the code this patch may be done in a
silly way but the result looks good on my computer. I was hoping that it would
be possible to have this improvement added to Gnumeric.
Can somebody let me know what the correct way to submit patches to the project
is? I have some other things I would like to work on in the future.
Regards,
Vanja
