  How do I create a scale drawing from an image?
Posted by: Smoo - 02-20-2017, 06:08 PM - Forum: General questions - Replies (3)

Hi all, I'm new to the forum and new to Gimp.

I'm a blacksmith and fabricator, and what I want to do is print life size drawings of objects from images so that I can use them as templates for cutting steel etc..

So lets say I wanted to make a replica of a knife from a picture. I import the image, cut round the knife, re-orientate it and correct perspective(if necessary), re-scale it to real life dimensions, create a line drawing version and print it out. I also need to be able to print things which cover more than one page for large objects, even things which could be a metre long or more.

I had a bit of a go but quickly started to come unstuck. I was able to draw round the knife, but I couldn't make it a new layer of it's own. Also when I rotated it, the top and bottom were outside of the layer boundry and I couldn't figure out how to stop it cropping the image.

I can probably do the line drawing bit ok. Unless I need specific angles and symmetry. But I'll figure that out when it comes up.

If anyone can point me in the right direction that'll be awsome!

Saw something about this in here but cannot find anything now Sad 
I downloaded ufraw so I could work on raw photos as well as jpgs, the program has a link in it to open up in gimp but nothing happens when I click on it. Saw there was some trouble with it so I downloaded the nufraw, says it can be used as a plugin to gimp?
Where do I put it? it is a 'tar.gz' file Huh

  Image size on hover
Posted by: anon_private - 02-17-2017, 09:08 PM - Forum: General questions - Replies (13)

I have made some icons.

I have placed them on the desktop.

When I hover the house over the icons, I note a square shape around the icons, but, in a few of them, I see a larger rectangle. I have cropped all the images.

I would like them all to be uniform.

Advice please.

  Help with modifying a text letter
Posted by: chrisj - 02-15-2017, 06:10 PM - Forum: General questions - Replies (2)

Thanks for putting up this Forum.

I have the text letter O in a layer(see attached), and I filled in the center almost completely (with pencil tool), but left a little unfilled, so it would look similar to a round head with a smile(see attached), however it looks kind of like a jagged smile.
Can you suggest a way to re-do so that the "smile" looks a little smoother (not so jagged)?

  'Up arrow' on value slider bar?
Posted by: OurJud - 02-14-2017, 09:37 PM - Forum: General questions - Replies (7)

I don't know if I'm missing something but there doesn't appear to be any logic or sure-fire means of getting the mouse cursor to switch to the little 'up arrow' icon which allows you to quickly change the values of brush size, opacity etc.

The other options are using the 'up and down' buttons on the slider, or to kind of drag it with the '|' icon, the latter of which is very fiddly and ineffective.

As you hover the mouse cursor over the value bar it will occasionally switch to the 'up arrow', but as I say there appears to be no rhyme or reason as to when it does this.

Am I missing something or is this normal behaviour?

  Drawing circles with the ellips tool
Posted by: anon_private - 02-14-2017, 02:58 PM - Forum: General questions - Replies (5)

Try as I may, I still cannot create circles.

I start to use the tool then hold down shift, but I still see an allipse. I see the same when holding down control!

Previous post reminded me of this. A friend from school days now lives on the west coast of USA and has a very nice boat. Also bought a equally nice boat on the east coast USA so that he can sail around the Virgin Islands.

Had to remind him that I kept my boat in the back yard.

  Beginners set up for printing.
Posted by: rich2005 - 02-12-2017, 01:01 PM - Forum: Tutorials and tips - Replies (3)

A look at setting up a canvas in preparation for printing. Video duration 9 minutes

A caveat:
Gimp comes from UNIX origins and printing in MS Windows is an add-on to interface with a Windows printer driver. Since printer driver software comes from the printer manufacturer, sometimes there is a less-than-perfect match.

If you have problems printing from within Gimp then export your work as an image and use some other Windows application for printing.

Whatever you do, when starting a graphic for eventual printing, it might be small, say a birthday card or it might be large, a poster, it is vital that the initial set up matches the overall aim of the project.

- Setup a new canvas at 300 pixels-per-inch for printing
- Use a preset Gimp template size.
- The Gimp Image menu -> Print Size dialogue
- The Gimp File -> Page Setup and Print dialogues
- The difference between high resolution and low resolution images.
- Printing imported images on a Gimp preset (A4 or US-Letter) canvas and the effect of printer margins.
