How to apply "Greyscale" feature to only selected area?

[pstein]

Assume I selected a part of a colored image.

Now I want to convert this selected area to a greyscale image.
.
When I simply select menu

Image--->Greyscale

then whole image is converted to greyscale. The current selection is unregarded

How else does that work in PSP X2?

A number of ways. One possible is to use the selection tool and draw a line/lasso around the required selection. The use Adjust/Hue Saturation to desaturation that selection.

Second way

1. Load image
2. Drag thumbnail from Layer Palette onto workspace to make a second image
3. Apply Image> Greyscale to that second image.
4. Back to first image and make your selection of what you want greyed out. Selection > Invert
5. Drag thumb of second greyed image onto the first image (copy and paste as new layer) and make that active.
6. Hit Delete key to remove all the grey area outsde the area you originally selected to show the color from the layer below.
This will work for any method of greying a layer.

Third way!

Duplicate layer.
Convert the lower layer to gray scale.
Make the top, colored layer active.
Use the erase brush/tool with the desired size, hardness and opacity to remove the areas required to expose the lower gray layer.
Merge finished layers.

Next!

Brucet said "Duplicate layer.
Convert the lower layer to gray scale."

Trouble is that that also makes the top layer greyscale which is why I did the dancing around creating a single layer to apply the Image > Greyscale to.
I was surprised when I did the copy and paste of the 256 color greyscale image that it also converted the number of colors back to 16 million colors.

Oops.

Greyscale will only apply to the whole image, including layers.

Is there any reason you can't just use Hue Saturation Lightness and lower Saturation to zero on the selected area?

If there is some reason that doesn't work for you, copy the selection, paste as new image, make that greyscale, copy it and paste it back into the selection on the first image. If it's something you do a lot it could be scripted to make it a one-step operation, including closing the pasted new image once it had been pasted back into the selection of the original image.

This worked for me without problems.
Its the easiest way I have read so far
