write text to an texture

Well hi, this is really spontaneous but I really need fast help

I was doing a BST representation in mogre using images with numbers.
For that i had to create the .jpg format images manually and put them in C:\MogreSDK\Media\materials\textures .

Now i need to rewrite the program to create the images while running, in other words, i dont want those images in materials folder, i want them to be created while the program is running to "improove" it... so every time a number is pulled and an object is created thets where i would like the image to be created.

This is how it works: it grabbs a number from a stack and it creates an object with the picture that has that number and well then comes the algorithm to make the tree.

I dont know how to create images from the code and thats where i need your help, i know its not hard and i would do it my self but i got eye surgery a few days ago do i shouldnt be using the computer and i need this for friday.

p.d. sorry for any wrong slepped words, english isnt my language.. the pictures are small, have a white background and a black number, numbers from 40-60
I'll leave the code below:

Hi abtrakt,

nice to see that you use Mogre for a presentation.

First of all:
Please use "useful" subjects for forum topics.
Most of them could have the name "help please". It's not good for the overview.
You can use the edit button of your first post to change the title. (please do it)

Mogre has an API call to save the current frame to a file.
Unfortunately I can't look to my source code now. But maybe you can find it yourself by searching in this Mogre forum or Ogre main forum. Sometimes Google is a better alternative to search for something on the Ogre website. (use the addition "site:ogre3d.org" for your google search)

Well, what was your question?
Save Mogre images to a file or to load an image file to the Mogre resources?

The second case is possible - also on-the-fly. If you need code, I can have a look to my application.
Maybe I can do it today. But perhaps this needs some days.

my question was how to create a texture with a label, on-the-fly.. not necessarely save it

OK, now I saw your new subject and know what you mean.

Search for keywords like "rendering to texture" or "RTT".

Some useful links are here:
