How to make text smaller?

How to make text smaller?
I am new to gimp and very limited with the program. I am very excited about slowly learning how to use Gimp.

I am currently working on making a map out of a satellite image. I am stuck trying to figure out how to get text to be small enough to be legible. I have cropped and resized the original image, It is 137x224 @ 72ppi. I want the text smaller, I think I cant get enough definition because the pixels are huge, text size 7 and under becomes like 6 squares per letter and there is no definition.

The same effect is keeping me from getting well defined and sharp lines. I try to stroke a path and the line looks like a row of squares instead of a line.

If anyone has any suggestions they would be very appreciated.

Pixels don't look like pixels because they are small enough Smile If you zoom on them, they appear as what they are: squares. 137x224 pixels is very small if you want to put text on it. It's closer to the size of a thumbnail than to a workable image. Why is the image so small?

Well, what I'm doing is making a disc golf course map, and individual hole maps from the course map. I started with an online satellite map that was low resolution (not sure if im using "resolution" correctly). I dont need a real detailed map so I am playing around with gimp to do some basic editing.

I took the overall map, then cropped out each individual hole, so thats why the image is so small. In theory the hole maps will look great and be extremely accurate. I just need to do some simple adding of tee's and holes, with a line drawn from the tee to the hole.

I'm having fun doing it and slowly learning the basics, I just get stuck here and there. I'm sure there is much better way to go about this but I'm just learning as I go. Here is one of the holes I have so far. I erased uniportant parts of the image, cropped all 18 holes, rotated them to all face the same way and sized them about the same so I can make tee signs out of them. That's the idea anyways. Lets see if I can attach one. Ahh, I don't know what format to put the image in or how to, I'll have to look into it.

But if you can imagine what I'm talking about.........Is there any way to draw in smaller pixels over these images?

RE: How to make text smaller?
The pixel, by definition, is the smallest individual element in an image, so you cannot have "smaller" pixels. You need to work on a bigger image with more pixels. If you are really producing a "schematic" of the golf course, you can rather easily produce "paths" that follow the outlines (greens, sandpits, ponds...) and can be scaled up and still produce very sharp images.

The size of the image in pixels depends what you intend to do with it and mostly the PPI (pixels per inch) resolution of the media. A computer display goes from 72PPI to 120PPI, while good quality print requires at least 150, preferably 300 or even 600 in some cases.
This means that a 4"x6" image for a web site (computer display) would be 400x600 pixels, and its print equivalent 1200x1800. What is important when you work in Gimp is the size in pixels. The resolution in PPI is indicative.

Ideal format for posting is PNG (no loss, supports transparency) unless it's a big photograph, in which case JPG is better.

RE: How to make text smaller?
Talking about sizes and formats, if I want a good sharp image at 400x600, should I always work on a larger scale and then resize before saving the final image? Sorry if this is off topic, but it is something that has been bugging me for a while now.

Thanks for the tip about PPI. I am guessing it will have a final affect on the end size of the image, right?

RE: How to make text smaller?
Better work directly in 400x600. The rescale algorithms are approximations. Of course, if you want both print and display versions, better work at 1200x1800 and rescale (the loss induced by the rescaling, especially if using Sinc/Lanczos, isn't that bad...)

RE: How to make text smaller?
Recently did some very small text and about the only thing you can do is turn off anti-aliasing.

A screen shot of with, then without, antialising at 8 & 12 pix size.

Not much room for improvement, you can go in at the pixel level and 'tweak' the odd pixel from foreground to background colour & vice versa but the bottom line is you can not have half a pixel.

Thanks everyone, you have been very helpful.

Ofnuts- I'm going to work on the paths-scale method, I have an idea of how that may work, hopefully that jives with how it actually works.

yes, likely the best solution...

For instance, I went from this photo
[attachment=684]

to this
[attachment=685]

(this is the path drawn over the photo, used as a selection, and bucket filled). I can scale it up to A3 size and it will still look sharp (made teeshirts with it).

RE: How to make text smaller?
Ok, I can use fuzzy select and get a great selection on exactly what I need. I can fill the background, but I cant fill the original areas of the image that are left, ie. trees, walking paths. If I could just save the selection path as an outline then scale it and fill, I'd be set.

I though inverting the selection would do the trick, but it still wont fill. If anyone has any ideas please let me know. I am attempting to attach one of the images I'm working with.

RE: How to make text smaller?
Hey my attachment worked! Small victories keep me sitting here!

So thats the image I'm talking about, eventually I want it to look like a simple caddy book picture, with solid colors. I'm kind of taking the long route to end up with a very simple drawing, but this is the best way I could come up with to make the maps very accurate.

Select the bush, and use Select/To Path. This will create a real path from the selection, that you can merge with an existing path, for instance.

RE: How to make text smaller?
aaahhhh hahaha! my fill was set to "fill similar colors" instead of "fill whole selection"! One step at a time! I'll figure it out!

I select and select to path, then when I hide the selection I have real nice smooth lines, but I cant seem to do anything with them. How would I just save the paths as an image and work off of that? The path lines being the only thing in the image.

RE: How to make text smaller?
With a path you can do two things:

1) "stroke" it (ie, Gimp uses it as a guide for a brush): Edit/Stroke Path or in the Path list, right-click+Stroke Path
2) Use it to create a selection (if it's closed): Select/From path, or in the Path list, right-click+path to selection
