Creating and using seamless texture sets

[StillCypher]

Very useful information! Thanks much!

Stupid question:

What do you do in the early part where you indicate to "make seamless using your preferred technique"? Is there a specific command that turns an image into something tileable? Or a specific set of commands?

Oh yes, you use Gimp with the patent pending 'Redrobes' filter

Or the link rob gave goes to a thread with a script implementation of it which does the same thing using ImageMagick which is a free image scripting language thingy.

There are other ones too tho but they arent called anything as good as Robs script...

Even stock gimp has a (poor quality) command Map->Make Seamless.

But if you google for "seamless tile tutorial" you get tens of thousands of hits.

There are also loads of dedicated programs just for creating seamless textures, but again, YMMV.

Thanks, plus I found the one Redrobes referred to in the post above.

Now... maybe a more complex question (or maybe just more stupid):

Firstly, what's the maximum size of an image like this?

Secondly, is it possible to make, say, only the top and bottom tileable, so that you can tile a column, vertically, but it won't tile horizontally...?

Firstly, what's the maximum size of an image like this?

Any size really. Most time based software uses a predefined size (like Dundjinni's 200x200 px) but if you are using a paint program, then any size.

Secondly, is it possible to make, say, only the top and bottom tileable, so that you can tile a column, vertically, but it won't tile horizontally...?

Now it is my turn to ask what might be considered a stupid question...

Why would you want to NOT tile both ways?

Why would you want to NOT tile both ways?

The source image may have features near the sides that you don't want to get distorted?

[Redrobes]

Well, if you look at my script/tut thing there are steps to do that wibbly shape horizontally to blend the top and bottom bits and theres another vertically to blend the sides. So skip either one of those but complete the rest of the sequence.

Rightly so....

I'm postulating, for the sake of argument, say, a background image with features on the left and right sides that, as Ghostman suggests, are desireable to be maintained, but that I might want to be able to tile vertically.

I don't have any immediate plans to do anything like this, but I'm just envisioning it's use in a website, for example, where you want a main text column with such a background image to expand downward as text is added to the page, but to maintain a fixed width, and thus maintain certain distinctive edge features.
