Save 50% Opacity to file (.tif or other)

[GregJones]

I need to edit an aerail photograph to make it partially opaque (I can do this part) and save it to file that , when opened in a CAD program, will be partially opaque.

Specifically, I need to overlay a partially transparent aerial photo over a topographic map (.tif image) and drawing entities in TurboCad. I seem to be able to accomplish this only by combining the images in PaintPro, then importing to TurboCad. This method does not allow me to utilize exact scaling in TurboCad.

Thanks for any help.

I'm a bit lost here. Do you need help with PSP or with TurboCAD?

PSP

Let me get this straight. You want to take a file from PSP that is slightly transparent and use it in TurboCad overlaying it on a map?

I don't think you can do that. I think you would have to set the opacity from TurboCad itself.

Turbocad will not set opacity (Autocad will) - all I have been able to do is set the opacity in PSP, overlay it over another map in PSP, then import into Turbocad. This is fine except the tools for overlaying the two maps are not as elaborate in PSP asin Turbocad - ie - correcting for the skew of an aerial photo when overlaying a map.

Thanks for the thoughts

Have you tried the perspective button? (I think that's what it's called, I'm at work and don't have PSP here to check.) Might this help? I'll have a look when I get home to check which button I really mean! ;-)

I don't use Turbocad, but I think you've answered your own question:

Turbocad will not set opacity (Autocad will)

However, as a starting point, I would recommend saving the PSP file in a standard format that supports transparency, such as PNG, PSP, PSD. This might give you the best chance. TIFF can support transparency, but it's not univerally supported.
