  Travels with my Wacom
Posted by: rich2005 - 04-06-2017, 02:13 PM - Forum: Tutorials and tips - No Replies

Difficult to put a category on this. Maybe a tip for users of old graphics tablets.

This is my Wacom Volito from around 2006 - 11 years old but still works in my regular linux installation. Does it work in Windows10? Yes - with lots of reservations.

   

Here is the epic - Travels With My Wacom - duration 5 min 40 secs.

  don't .xcf save parasite information?
Posted by: trandoductin - 04-06-2017, 05:10 AM - Forum: General questions - Replies (4)

I tried setting image parasite
using this in one script

Code:
parasite = gimp.Parasite("gimp-comment",0,comments)
image.parasite_attach(parasite)
and this in another script

Code:
comment = image.parasite_find("gimp-comment")
pdb.gimp_message(comment)
Everything seems to work okay as long as i have the .xcf opened.
If i close the .xcf after first script
and reopen .xcf the 2nd script fails getting parasite.
But when i tested exporting as .jpg
then the 2nd script would work
It seems as though parasite is not being saved when you save .xcf but does save if you export to .jpg.

Any ideas? on how to make it work for .xcf as well?

  Text on mouseover of hyperlinks not working
Posted by: BonnieD - 04-05-2017, 07:31 PM - Forum: General questions - Replies (3)

I loaded my image/image map onto a webpage (a sharepoint wiki page). I was hoping that the text I added in the mouse-over box in the GIMP image map tool would appear in a small pop-out when someone moused over any of the hyperlinks that I have mapped in the image.  This is currently not working.  What am I missing?

Question How to change resolution w/out changing size?
Posted by: drpeppercan - 04-05-2017, 03:53 PM - Forum: General questions - Replies (2)

Hi all,

I just want to decrease the resolution of my image. The problem is that every time I try it also affects the image's size.
I go to the Image menu, then Scale image.

Thanks guys,

  smooth out colours
Posted by: tekett - 04-05-2017, 05:21 AM - Forum: General questions - Replies (11)

the colours transitions looks like a staircase or height curves on a map. how would i go about to smooth out the colours? http://prnt.sc/eslewq i just want this to be a smooth transition. if there is no automated function or script or whatever i dont care, il do it manually then with one of the brush tools. the image im working with is quite huge its 8160*26144, so the picture in the link is like 1000*1000 pixels of my image, so i have allot of pixels to work with so i can use as much different colours as the program can handle in order to smooth it out.

Photo Wacom tablet with Gimp?
Posted by: Nateart - 04-04-2017, 06:55 PM - Forum: General questions - Replies (6)

I have succeeded in getting my Wacom intuous 3 6x8 pen tablet installed into Windows 10
Is this functional in Gimp?... like varying line width by pressure applied?
If so, how do I set it up in Gimp?

I've done illustration for books, magazines, puzzles etc. since 1970... take a look if you like =

I have seen several YouTube videos featuring GIUMP with a dark grey interface.  I am wondering how to change from white to the dark grey. 

Thanks

  Make an animation from a video
Posted by: rich2005 - 03-31-2017, 09:15 AM - Forum: Tutorials and tips - Replies (1)

To put this in Other graphics software or not... The ultimate object is to use the result in Gimp..it is a tip

A sometimes asked question is: How to convert a video - something.avi / .mp4 - to individual images in order to make an animated gif.

A common reply is use the Gimp plugin GAP. The video extractor in GAP sometimes fails on modern video formats so here is an alternative using a command line application FFMPEG. 

Linux users can easily install FFMPEG, for Windows users, a convenient way is by installing Imagemagick which comes with FFMEG.

If you do not want to watch the video explanation which has a bit more detail, the basic command is; 

Code:
ffmpeg -i inputfile.avi -f image2 imagename-%07d.png

To see how to reduce the number of frames and a demo, the video is;  https://youtu.be/PXxECG_6YvA duration 4.5 minutes

  Gradient implementation and opacity questions
Posted by: jminternelia - 03-30-2017, 01:56 AM - Forum: General questions - Replies (2)

Hello all, new here, and fairly new to Gimp.

Without overly complicating it, here what I am trying to achieve.

The image below is something I am trying to replicate. I'm going to create a wind dial for Rainmeter. However, there are two things I'm having trouble with, and hoping maybe you all can help me out.

As you can see the image is broken down into some type of gradient. How would I go about implementing that sort of gradient in my own circle? I am not using any actual part of the original image, so I am using it's size as a guide. Is there some way to divide a circle into 24 equal parts and bucket fill each one?

And here's the second one, that I think I already know an answer to, but as you can see below, the circle also doesn't have full opacity, meaning, the color values you see aren't what they would look like against my wallpaper, which is basically a replication of the "grid" background. Thus my question is, is there some kind of "smart" way to determine the color values shown below but what they would look like either with the black background removed OR if they were 100% opaque?

The end goal is to create an asset of higher resolution and quality, but with accurate color values and opacity reproduced by hand.  

Hope I explained correctly.
