Welcome to TalkGraphics

The trial versions are fully functional.

If the pattern is a bitmap, and it sounds like this is what you want, import the image into Xara (either File > Import...) or drag and drop the image onto the page from the desktop or an Internet Explorer folder.

Select the text, open the Bitmap Gallery, select the image and press Fill.

You can select the image with the Fill Tool (the paint bucket) and then use the fill path arrows to resize and/or rotate, the fill. Drag the center square where the two arrows originate to move the texture around inside the text. The small boxes at the ends of the arrows let you scale and rotate the fill.

Any fonts that are installed in your Windows Fonts folder will be available in Xara. You cannot import a folder as such. But if you have a folder with say a dozen images, select all the images and drag and drop the images into Xara.
