  Gimp selection tools for beginners
Posted by: rich2005 - 10-30-2016, 02:09 PM - Forum: Tutorials and tips - No Replies

For Beginners to Gimp, a look at the selection tools and briefly how they work.

To keep these demonstration videos to a sensible length, the subject is split into three parts.

Do not like videos? then the Gimp manual references are

Chapter 14 starting https://docs.gimp.org/en/gimp-tools-selection.html
Chapter 7 starting https://docs.gimp.org/en/gimp-using-selections.html

1. The various selection tools, plenty of them, rectangle, elliptical, free-select, fuzzy, color, scissors, foreground and quickmask.

2. Modifying a selection with the selection modes and Selection Menu options.

3. Selections and the transform tools: move, rotate, scale...etc.

  Impaint & Content Aware Filling
Posted by: Espermaschine - 10-28-2016, 07:56 PM - Forum: General questions - Replies (2)

Has any of you guys figured out how to use the various G'MIC Impaint filters ?

I dont do much photo manipulation but content aware filling is something i need to use from time to time but i find it hard to use it properly.
Most of the time i end up using 'Heal Selection' (resynthesizer) instead.

David Tschumperle seems to be unwilling to answer questions as to what the individual sliders do and that Pat David tutorial didnt help much either.
Changing the sliders without knowing what im doing, doesnt work very well, and the preview is inaccurate anyway, so experimenting with the filter is time consuming and frustrating.

  Box of tricks, aka adjustment layers
Posted by: Espermaschine - 10-28-2016, 01:37 PM - Forum: General questions - Replies (4)

The idea for this thread comes from a conversation with CRogers on G+ and a script package from deviantart.
Somebody was asking when we finally gonna get non destructive adjustment layers as in Photoshop, and i remembered the deviantart script pack which is basically a memory aid for people who dont understand layermodes.

So here are some tricks how to imitate adjustment layers for non destructive image manipulation:

Saturation Adjustment:
create a new black layer on top of your (color) image and set the Mode to 'Color' (you will get a b/w image).

Inversion Adjustment:
create a new white layer on top of your image and set the Mode to 'Difference' (you will get a negative)

Sharpening Adjustment:
get RobA's HighPass Filter script (registry.gimp.org/node/7385), run it on your image and set the new layer to 'Grain Merge' or 'Hard Light' (this will sharpen your image)

Adjust Lights, Darks or Mids:
use this tutorial (clownfishcafe.blogspot.co.uk/2013/11/color-pop-on-midtone-grayscale.html) to manipulate specific value parts of an image with a layermask.

Any more non destructive tweaking tricks ??

  Removing unnecessary paths in Inkscape
Posted by: Ofnuts - 10-25-2016, 10:40 PM - Forum: Other graphics software - Replies (9)

I have a company logo that I want to use in an SVG icon file. The logo is a symbol followed by the company name.

I just want the symbol. I found how to clip it, but this is just masking stuff, the SVG still contains all the useless paths for the company name (and some software doesn't really pay attention to these masked off paths).

So, how can I remove all these extra paths?

  Cut-Out Text
Posted by: rich2005 - 10-25-2016, 05:47 PM - Forum: Tutorials and tips - Replies (13)

Cut-out text comes up frequently. Want something like this
or this

It is the same process using a layer mask.

Aimed at beginners, demonstrating
- resize a layer
- a quick look at how a layer mask works
- using alpha-to-selection to select text shapes
- put the selection straight into a layer mask

No 30 minute epics here: only 5 minute video

  Pasted image not visible
Posted by: Yash Pal - 10-23-2016, 02:49 PM - Forum: General questions - Replies (7)

I copied and pasted a part of an image in the same image, after extending the canvas size to accommodate the pasted part - the background of the image was made transparent. The pasted image is not visible, though the marching ants of the selection are seen. I changed the background to white, (new layer - white; and put the white layer below the existing layer, but still the pasted layer cannot be seen (not visible).

I am making some mistake but do not know it. Can someone please tell me how to make the pasted layer visible?

OS: Ubuntu 14.04; GIMP: The version available in Ubuntu Software Centre (2.8.18)

 I had asked this question in another forum; so far, there is no reply.

  making a displacement more "fluid"
Posted by: Espermaschine - 10-22-2016, 06:14 PM - Forum: General questions - Replies (8)

When i displace a gradient with a displacement map, i get slightly jaggy edges.
Is there a way to avoid this ?
Or does it require a higher bitrate image, so that there is more information in the gradient ?

Using 'Adaptive supersampling' when drawing the gradient does not help.

  Saving selections in a channel
Posted by: Espermaschine - 10-22-2016, 06:09 PM - Forum: General questions - Replies (4)

When i type text, then go to 'Text to path', make a selection from that path and save it in a channel, that selection is superior (more precise) to using 'Alpha to selection' and saving that in a channel, right ?
