Re: [Gimp-user] how to scale down image without quality loss

2016-01-24 Thread David 
For scaling down vector images, use Inkscape.
Otherwise, if you still use GIMP, make sure that you import the image at 300dpi 
and resize from that - but for a better visual result, I highly suggest using 
Inkscape

I don't think so: Here is Line 62 from the relevant gegl file loader:

 command = g_strdup_printf ("dcraw -4 -c '%s'\n", op_raw_load->path);

If you want the image to appear on paper at 28mm high at 100dpi you can 
calculate the size of the image in pixels using that information.


28mm high at 100dpi works out to 110 pixels. If you are trying to scale an 
image that is over 800 pixels high you are losing a lot of information. I 
would suggest you up your dpi value to at least 300 for such a small image.

Then why were you posting in the thread about NEF support (or RAW, in
general) for 2.9.x?

You've got UFRaw installed?

[Gimp-user] Looking for default locations of program icons and keyboard shortcuts list

2016-01-24 Thread Aner Ben-Artzi 
Hi,

I'd like to create a custom keyboard (print stickers) for GIMP.  However, I
want to do this in a programmatic way so it can stay up-to-date with
version upgrades and customizations.

So I'd like to be able to get the following items in order to
programmatically combine them into a file that can be printed onto sticker
paper:

   - list of current keybindings <-> action
   - list of action <-> in-program icon image (preferably the larger icon)

This would allow me to place up to 4 (neutral/shift/ctrl/ctrl+shift) icons
in a square to be printed and stuck onto the appropriate key.

Given how useful it is to have a separate tool selector hardware and how
cheap keyboards are, it seems very useful to keep around a separate
hardware keyboard purely for when I'm in GIMP.  It doesn't even have to
have the letter keys on it because there is no problem having it connected
simultaneously with the typing keyboard.

I considered putting this into an app to allow me to turn a tablet into a
custom keyboard that sends the shortcut keys, but there is no substitute
for separate, hard, plastic keys.

I'd like to do this in Linux, and later see if anyone wants this for
Windows/OSX.

Thanks,
Aner Ben-Artzi

Re: [Gimp-user] Can't open nef images in gimp 2.9.3

2016-01-24 Thread Rick Strong 

Hi James,

You may not be aware that Nikon provides two FREE programs for working with 
NEF files.


- ViewNX-i   for transferring from your card reader or camera (click 
"Transfer" icon), among other things.
- Capture NX-D   for working on exposure compensation, Active-D lighting, 
etc.


Both programs can export to JPEG, TIFF 8bit and TIFF 16 bit files. This is 
not the answer you were hoping for, but it is a work-around for now.


I believe (new GIMP user here) that GIMP only opens TFF 8bit files, or 
converts 16s to 8s, so saving in 8bit TIFF saves any loss in conversion.


I use the two Nikon programs all the time because I found Lightroom to be 
lousy.


Cheers,
Rick

I am talking about dcraw-load.c. I have it working by modifying

  command = g_strdup_printf ("dcraw -4 -c '%s'\n", op_raw_load->path);
to
  command = g_strdup_printf ("dcraw -4 -c \"%s\"\n", op_raw_load->path);

I do get buffer overrun and so some of the images are not rendered
correctly as I have reported in gegl-developer list.

I don't have libraw installed but have dcraw 9.26.
