Whenever there is a rasterized scan our automatic selection tools fail. I therefore remove the raster with a despeckle tool first. This will also considerably reduce the image size after compression.
We can then quickly adapt the image color levels as done here:
These are the three steps I had to take using Gimp 2.8:
Filters - Enhance - Despeckle: non ...

Try:
Increase the pixel count aggressively (e.g. ~1530px wide to 10,000px), apply a strong blur filter, and then reduce the image back to the original pixel count. This will get rid of (most of) the halftone dither.
Use the magic wand tool with a setting around 20-30% and "contiguous" enabled. Select the outer grey area, invert the selection and then ...

Seems pretty straightforward with Photoshop CS6. I used the dropper tool to select the general background and did cleanup with the quick selection tool.
Note:
If the selection of the background ends up breaking due to the "grid pattern", you can work around it, like I did, by duplicating the later and applying a blur filter to smooth it out, then ...

In Photoshop, the best tool for that job would be the Pen Tool, as it will create nice straight lines and curves. If you don't have the patience for that, the quick selection tools will do an ok job, and you can use Quick Mask to clean up the selection

It looks like it could be very difficult because it isn't actually grey. If it was an actual grey, you could use curves to make the grey white, but it's a dither of black and white dots so you'd just get a more strongly specled image. Manually clearing it up is pretty much the only option I could see. Magnetic lasso might not even work well.

I think where most of the stained glass tutorials fail is in capturing the irregularities that glass has. Filters work with patterns, and the final result is usually not very realistic. An example of real stained glass:
When using filters, the result is usually flat. Glass looks sort of the same in the whole window, they loose the craftsmanship beauty the ...

I don't know of any general way to do that, and indeed, in some cases an automatic solution might not even be possible without some way to distinguish the text from the background. (You could, for example, decide that the color a given pixel had in a majority of the images was the background, but that could fail for pixels that were actually covered by text ...

There's a great (freeware for personal use) tool called AMP Tile Viewer that lets you very quickly check whether an image is tileable and how it will look tiled. I use it all the time and it works just great. No need to make patterns in Photoshop you will never use or have to delete afterwards.

You can use a paragraph rule to block in the whole measure or the text underline to highlight just the text. The trick is to get the offset just right then set a width value that matches or exceeds your leading value.

I used table for my own report and it worked really good for me. For every code block that I needed, I just did a copy/paste of previous table. For syntax highlighting , I defined character style first but it was tedious to apply those styles for every pieces of code. Therefore just copied the code from IDE, preserving the color and font, to InDesgin. Here ...
