Hey everyone...


I recently picked up a Sony digital camera and am interested in cropping pictures taken in 16:9 mode to exactly 1920 pixels wide by 1080 pixels high so that I can display them on my plasma with NO SCALING (i.e. 1:1 pixel mapped) through my HTPC.


Are there any open source (freeware) photo editors which can allow users to preview an image, specify a crop area or window of 1920x1080, then drag that crop area/window within the larger previewed image to select only the 1920x1080 pixels of interest?


Thank you in advance for any replies.

whats the resolution of your camera?


your tv is about a two megapixel display device (1920x1080=2,073,600=2.07 megapixels)


your image is going to be DOWNSCALED, not upscaled if you want a 1:1 pixel map. You will be tossing out 80%+ of your image.

Thanks... here's a cut/paste description of the camera:
Sony Cyber-shot DSC-HX5V 10.2MP CMOS 10x Wide Angle Zoom Digital Camera with Optical Steady Shot Image Stabilization and 3.0 inch LCD

Yea, you nailed it... 10.2MP cropped down to 2.07MP = 80% image loss

Chances are that your digital camera is going to look pretty poor at such cropping. The 1:1 pixel-peeping quality of most cameras does.


I would have had a look at GIMP.

+1 on gimp



1:1 pixel mapping is not really important, just crop to 16:9 proportion

Actually, I read in the user guide that this camera has two 16:9 still image modes...


16:[email protected] (3648×2056) for viewing on a high-definition TV, and for prints up to A4 size, and


16:[email protected] (1920x1080) for viewing on a high-definition TV.



So I guess I now know which mode I should use

I'll definitely take a look at GIMP. Thanks for the suggestion!

I use my camera in 4x3 mode to use the full MP of the camera. Windows Photo Gallery has an adjustable 16x9 setting that I use to crop what I want from the photo. Works nicely, you should give it a try.

Don't bother. If you take thousands of photos, like I do, you will soon tire of cropping them. I save my images as 10mp DNG (raw image) files. They display just fine in WMC as a slideshow with a black background. Of course the ones with vertical aspect ratio look small, but usually there is a reason why they were taken that way.
