Topic: help editing mrsid files on a 64bit machine

[alanjt]

The old mrsid viewer, that also gave you some editing capabilities, doesn't work on 64bit machines. Does anyone have a solution for editing them? Actually, I just want to make them greyscale instead of color. I can change this if inserting in mapwspace, but it bogs the drawing down, can't xref, and you can't freeze in certain viewports.
I *thought* you could change any inserted image in autocad to show greyscale, but I was either wrong or can't find the option.

Have you tried IrfanView?

You can change images in AutoCAD, but need Raster Design.

I tried that once before, but it stripped out all the coordinate data.

We have infrastructure design suite, so Raster design is available, but I know nothing on it's use. Will have to look into that. Thank you. Once I alter the visibility of the image (change from color to bw), will it display properly when I open the file again in civil 3d?

Images are basically an XREF, so any alterations made (and SAVED) to the image file should stay put.

Can you use a virtual PC running 32bit windows to use old program? (I don't know how but I've heard about it)

Right. I was thinking it would be editing the state of the object within the drawing. I opened "raster design for civil 3d" but I couldn't figure out anything different. How would I edit the image from there?

If all else fails, I might give that a try, or find one of the xp machines sitting around and do it on there, but I'd rather have a non-bandaid method. :\

I keep the menubar on, so ribbon location may vary, but on theRaster Pulldown, select Image Processing, and then Change Color Depth, and you should have a grayscale option

When I opened Raster design, it didn't look any different that c3d. I'll have to make sure the menu is actually loaded properly and check it out then. For the time being, I took Ron's suggestion, and after finding the mrsid plugin, I was able to convert the sid to greyscale and save as a jpg. Sadly, it lost all it's coordinate data, so I had to manually place and scale once I inserted the images into my drawing.
Thanks guys. I still swear you could set an image to greyscale in older versions, but I'm sure I'm just misremembering.  :ugly:
