Making images partially transparant in Draw

Phelixfil · General User Joined: 29 Nov 2010 Posts: 10 Location: ES

I have two black and white images and I want to place one on top of the other. When I do this the square white frame of the overlayed image becomes visible. Is it possible to transform this image so that it comprises Black and Transparant (Instead of Black and White)?

Yes, provided you use a graphics file format that supports transparency. jpg does not. An alternative might be to crop the white border away.

Hi Thanks or that. The images are cut and pasted from the internet so I don't know how I would change them so that they become graphics files. I'm also not sure how I would go about cropping.
The image is square at the moment and needs to be cropped to form a circle. Any suggestions gratefully received.
Cheers, P

You could right-click the image, then choose "wrap", then "edit contour".

It doesn't give me the option to "wrap" when I right click...

I definitely don't see the option "wrap" when I right click the object

Still struggling with this one...
I am using OOdraw. I have two B&W images. They were cut and pasted from the net.
I want to superimopose one image on top of the other. The image that goes on top is a circle. When I do this it becomes apparent that the image is not a circle but a square.

In order to get around this problem I have drawn another circle superimposed that on top of the circle I want to put on top of the image. Selected both those images and then followed: Modify, Shapes, Intersect. This has the desired effect of turning my image into a true circle. However the circle I have drawn becomes the dominant image and I can no longer see the image I want.
I have tried sending it to the back and making the filling transparent but no joy Crying or Very sad

If anyonone out there has any ideas I would be very very happy to hear from you.
Cheers,
P

Try clicking the image that must be "dominant" first, then the circle. Then use the "Intersect" command.

In order to access the commands "Modify" "Shapes" and "intersect" I have to drag over both objects (the one superimposed on the other) to highlight them both. If I click on the topmost object as yuo suggest, they aren't both highlighted and the "intersect" command is not available.
This is really very silly but I am sure there must be a solution there somewhere and I'll bet it's not that far away

Click the first object, then hold the shift key pressed, then click the second object.

Yup, tried that already and something weird happens.
first click highlights the first object (8 green squares) and the second click (holding shift) now unites the two objects as if they were one (8 green squares). The two objects are now fixed and I can move them all over the page but can no longer superimpose one on top of the other.

... then select the command "Modify - Shapes - Intersect".

Yup that too. Then they disappear completely!
