tiff files and how to trim

I want to import a 7.5 min quad over an enchroachment area to depict the area where illegal fill was placed.  This fill not only is a trespas, but has altered the natural drainage.

I only need to use a small portion of the quad.  How can it be trimmed?

Thanks

 A WORK AROUND

print tif file to pdf.

then using say pdf exchange viewer zoom in on pdf file so screen takes up the portion you want and then print that "current view to another pdf , convert that back to tif  if required, using pdf edit  convert back to tif.

or with pdf file in pdf exchange viewer use their camera function to take picture of required area , paste into word document to fit page and then print that page to pdf , using pdf edit  convert back to tif.

There are many programs that allow you to crop photos.  A TIFF is a type of raster image file (aka photo).

I recommend Microsoft Picture Manager.  That program came with the version of Office that I have on this computer.

It will be much more difficult but you could also use the MS Paint program that comes as a part of Windows.

You could also use the Snagit Editor.  (Snagit is an awesome tool from www.techsmith.com) 

If none of these options are what you have in mind, send the tiff to me and let me know how much to trim from each side and I will do it for you.  If I know how much I am trimming from an image it takes less than 30 seconds to open and trim the file.

Snagit is great. But you did say "import", right? Into what? To depict a trespass you wish the end product to be spatially correct, right? Many Quad/tiff products are "registered" i.e. Geographic Coordinates/ Lat/Long. If your final product is CAD, you can register a clipped image using digitized coordinates. A better way is to export the desired area using a GIS type product. That way the integrity of the original data set stays intact without the distortion you get using a purely raster approach.

Thanks a bunch folks!!  I did a lot of reading into cad and found that once I brought in a rater image and then go to Tools and properties I can clip the image and use the transparency command to make the overlay look good.  My pdf suite 2010 has geospartial tools that work well.  I did not realize I had thar paricular program since I do not need such ability often.

Still, I liked what was sugested and followed through with them. 

Again thanks and have a nice day

Gee, I got in late on the discussion, so it looks like the question's been answered. But, I'll throw in my 2 cents worth anyway.

You can trim images with the "CROP" feature of Microsoft Office Picture Manager, but I often use IRFANVIEW (freeware) for image managerment. It will read a large number of image formats, including SID, and will export to nearly any other image format (except SID).  Of course, the georeferencing relationship between the TIF and the TFW will be lost anytime an image is cropped and no longer matches the extents of the TFW definition.

I use Blue Marble to crop & georeference images. But it looks like I'll be looking for something else since they tripled the annual subscription price.
