Re: [Gimp-user] Book cover image density /resolution etc..

[Tobias Jakobs via gimp-user-list]

Hi Mark,

I think you are trying something impossible. 300 dpi = 300 dots per inch
(or better ppi = pixel per inch). If your book is 6x9 your image bust be
(6x300)x(9x300) = 1800x2700 pixel. Every thing else will not work! You
can't change the dpi without changing the number of pixel and the other way
around.

Regards,
Tobias

Hello,

there is at the moment no developer/maintainer for the DDS plugin, have a

Re: [Gimp-user] Wronr reading of 16 bit tiff

[Tobias Jakobs via gimp-user-list]

Hi Andy,

please open an issue in the Gimp issue tracker and attach an example file:
https://gitlab.gnome.org/GNOME/gimp/issues

Some scanners create  4-channel/12bit encodedimages. Then the 4th channel
is an IR channel that is useful for reducing dust.

Tobias

Each individual owns the source code of GIMP.

No.

He is the biggest contributor to GIMPfor years and has a lot of respect in
the community. Have a look at the numbers:

Some history:
Gimp was first developed with Motif as UI toolkit. Motif was not open
source. That's why the GIMP developers created GTK (GIMP Tool Kit)
KDE was developed with Qt as UI toolkit, but Qt was not open source at that
time. That's why GNOME was started to get an complete OSS desktop. GNOME
chooses GTK as toolkit.
That's the main reason, why they share so much infrastructure.

GIMP has no foundation but people asked for donating to GIMP. To make that
easy the GNOME foundation cares about the GIMP money. As far as I know, the
GIMP team pays for this service and the infrastructur.

Re: [Gimp-user] Question about displayed values on Histogram window

Hello,

if you have an 8bit image it's from 0-255, if you have 16, or 32bit images
you get the values from 0-1.

Re: [Gimp-user] Suggestion for opening raw images

[Tobias Jakobs via gimp-user-list]

Hi Rick,

as Guy already wrote, Gimp 2.8 only supports 8-bit. Gimp 2.10 supports
16-bit as internal format and in the raw loader. And perhaps you are
interested, Gimp 2.10 has support for the HGT file format, gathered by
the Shuttle Radar Topography Mission (SRTM). I blogged about it here:
https://dablogter.blogspot.com/2018/01/gimp-now-supports-hgt-file-format.html

And I have an blogpost how to import the NOAA GLOBE elevation files here:
https://dablogter.blogspot.com/2018/09/howto-open-elevation-data-from-noaa.html

What is missing is import of 32-bit float values in the "Load Image
From Raw Data"-plugin. I opened a feature for that:
https://gitlab.gnome.org/GNOME/gimp/issues/2804

Do you have a link to one of thePDS images?

Regards,
Tobias

Perhaps xdg-open is a good alternative to a hard coded browser.
Xdg-open opens a URL in the user's preferred browser:
