You guys experiencing this as well ?

I fill a selection with white, open the Gaussian Blur, play around with the values and everything looks fine but after i hit OK, the blur looks weird and has some kind of halo....

  Duplicate layers question
Posted by: Nigh - 05-06-2018, 12:04 AM - Forum: General questions - Replies (5)

I have a circle that I want to add a small rectangle to the top and bottom. (Think like an apple stem). So I have the circle on one layer. 
I create new layer and make the "stem" with rectangle tool. 
So far so good.
Now I want my "stem" to be identical on the bottom. So I want to duplicate layer nd then flip the new layer so it' now on bottom.

My problem is this...
When I flip the new layer, the 1st "stem" layer flips also!
Now I have 2 on the bottom and none on top. I'm pulling my hair out!

Why does the other (not highlighted) layer flip also?
More importantly, how do I stop this from happening? 

Thanks in advance, 
Nigh

  Writing IPTC metadata to jpg?
Posted by: sshoults - 05-05-2018, 07:04 PM - Forum: General questions - Replies (2)

Hello, bit of a newbie here. 

I am trying to add keyword metadata in GIMP (2.10, on a Windows 10 laptop) for microstock work. I've found the metadata menu, added description and keywords etc in the appropriate boxes - but when i export to jpg it doesn't seem to be there.

If i open the file using irfanview and check the IPTC, there's nothing there. Shutterstock has picked up the title but nothing else (picks up the keywords I add with irfanview though); 123RF manages to find the keywords but not title or description. 

Am I doing something wrong or is it just the quirks of various sites and/or programs? Any suggestions for a foolproof method?!

Thanks! Confused

  Re-setting up tablet
Posted by: DrCyanide - 05-05-2018, 04:10 PM - Forum: Installation and usage - Replies (2)

I'm trying to get my graphics tablet to work with 2.10. It was working with 2.8, but the update (with it's uninstall process) must have deleted my settings and I'm having issues setting it back up.

  • I'm using a Huion H85L tablet (if that matters)
  • Input Devices has the mode set to Screen
  • Device Status correctly identifies the tablet is in use when I press down
  • Brush Dynamics is set to Pressure Opacity
But despite all that I'm unable to draw with the tablet at all, not even without pressure sensitivity (unless Gimp momentarily thinks the tablet is my normal mouse). When I put the pen to the tablet the dotted outline of where the pen is locks in place, but it doesn't follow the pen. The cross hair with the brush icon follows my pen, but isn't leaving marks. If I press down hard at first it leaves a mark (which seems to vary in opacity), but I can't move it. 

Any idea what I'm forgetting for setting it back up?

Edit: Looking at some advice from people who had issues with older versions I tried installing the 32 bit version instead of the 64 bit (on a 64 bit machine). In that mode, the Device Status says that the Graphics Tablet is never active, insisting I'm using the core pointer. On the bright side, I can draw with the tablet like this, but I have no pressure sensitivity.

  fit image in windows
Posted by: gimp-artist - 05-05-2018, 01:11 PM - Forum: General questions - No Replies

I have intuos tablet. I mapped a button for the "fit image in windows". The shortcut is "ctrl+shift+j". When I push the button on intuos the picture fits in windows, but sometimes the image is a little out of the center. Do you know why?

  Fonts
Posted by: gimp-artist - 05-05-2018, 11:26 AM - Forum: General questions - Replies (4)

I'm testing how fonts are working in gimp. I want to install a lot of fonts. Does anyone know where to get fancy fonts and to make fancy fonts? Is it okay to use downloaded fonts for my art-work, let's say for youtube or facebook? Thanks for reading.

I'm testing the text tool, especially the "from right to left" in the context menu. It doesn't do anything. It is the same status before clicking the menu. What am I missing here?

  Exporting for facebook - blurred image
Posted by: SerDom - 05-04-2018, 07:21 PM - Forum: General questions - Replies (2)

Hi all,

I'm a newbie to gimp, going fast through the learning curve and (more or less) getting done what I need done.

However, one point where I'm failing dramatically is in the quality of the exports. I look at gimp and the image looks great, but when I export it into either jpg/png/whatever, try to set all settings to maximum quality and the result is still not optimal:

https://www.facebook.com/clinicadentalel...=3&theater

Pixel is 1100x680 (From memory) which I was given as the ideal size for facebook.

Any advice as to how to get a better resolution?

Thanks

  GIMP 2.10 a brush in the filter parameters
Posted by: dinasset - 05-04-2018, 12:27 PM - Forum: Gimp 2.10 - Replies (13)

Hi,
in my activity of porting my filters to 2.10, I faced a strange behavior:
- there is a filter (running on 2.8) which as a "brush" parameter in the definition  
- trying to see it under 2.10 it was in the menu but not showing its menu when launched
- after some trials I discovered that removing the filter name from the parameters it was showing, but..
  only once (unless resetting all the filters)

So I decided to write a couple of test filters, one with the brush parameter (but set to None), the other one which uses the active brush.
The behavior was confirmed:
- using the first one I can see it and run only once (unless resetting the filters)
- using the second one I can see it and run as many times as I like

Ther same 2 filters included in my 2.8, show up and run always.

Hence I post here these 2 small filters; if someone is so kind to double-check them, I will appreciate 
The first one

Code:
#!/usr/bin/env python
from gimpfu import *
import random


def testBrushAsParm (inImage, inDrawable, inBrush, Run) :

   pdb.gimp_context_push
   pdb.gimp_image_undo_group_start(inImage)
   
   # set parameters for drawing the lines
   pdb.gimp_context_set_brush (inBrush)
   distance=100
   count=int(inDrawable.height/distance)
   h=0
   for h in range(count):
       x1 = 0                                  
       x2 = inDrawable.width                
       y1 = 25+(h*distance)              
       y2 = y1
       #info_msg ("x1, x2, y1, y2, Dw, Rh = "+str(x1)+",  "+str(x2)+",  "+str(y1)+",  "+str(y2)+",  "+str(Dw)+",  "+str(Rh))
       pdb.gimp_paintbrush (inDrawable, 0, 4,
                (x1, y1, x2, y2), PAINT_CONSTANT, 0)  
       h+=1
       
   pdb.gimp_image_undo_group_end(inImage)
   return()

# This is the plugin registration function
register(
   "testBrushAsParm",    
   "To test a Brush As Parameter",  
   "This script tests a Brush in the Parameters.",

   ],
   [
     (PF_DRAWABLE, "odrawable", "Output drawable", None),
   ],
   testBrushAsParm,
   menu="<Image>/Test",
   )

main()
The second one

  Recommended beginner xp-pen graphics tablets?
Posted by: nanping - 05-04-2018, 06:25 AM - Forum: Windows - No Replies

So, I had a black XP-Pen G640, it was my first tablet and I had it for almost 1 year, but recently I lost the pen and I can‘t buy one where I live so I would have to buy it online, like I did with my tablet. So instead of that, I decided to just buy a better one. Screen Tablets are too expensive for me, so I was looking at the XP-Pen Star06 , wich I've heard is called the best non-screen tablet, but it was also a little bit on the expensive side for me. In my opinion the XP-Pen G640 was decent, but I also dont have experience with other graphic tablets, so right now what I'm looking for is something in the middle between a XP-Pen Star06 and the XP-Pen G640 quality-wise, that will also hopefully be not as expensive as the Star06 .

Looking for a relatively cheap graphics tab (under £100). It does not have to have a display but should connect to my mac and be compatible with photoshop.

I have little experience in that area so I am hoping you can

What would you suggest?

rich: my suggestion is do not advertise and buy a Wacom tablet
