kufloyd Posted March 5, 2017 Share Posted March 5, 2017 I have a question about opacity of objects. In the attached file, object 1 has an opacity of less than 100% and is on top of object 2 which has an opacity of 100%. The problem is that object 2 starts to show through anytime object1's opacity is less than 100%; if object1's opacity is 100%, it doesn't show through. Is there a way I can reduce 1's opacity and not have 2 show through? I tried changing 1's opacity in both the color panel and the layers panel. thanks. opacitytest.afdesign Quote Link to comment Share on other sites More sharing options...
Hokusai Posted March 5, 2017 Share Posted March 5, 2017 kufloyd, The only way I know of is to use the boolean operations to remove part of the green rectangle so that it doesn't show through the purple (or navy one). The only problem with this is, there is going to be a white line show up or you will need to extend one of the rectangles just slightly to create your own "bleed". Please see my example. You'll have to add the bleed part. Hokusai opacitytest.afdesign Quote Link to comment Share on other sites More sharing options...
kufloyd Posted March 5, 2017 Author Share Posted March 5, 2017 thanks for the reply, Hokusai. I did the divide operation and it worked for those 2 simple rectangles. Now, I tried it with a slightly more advanced set of objects (see attaches leaves document, layer 5). I can't seem to figure out how to get rid of that white line...not sure I understand your suggestion about extending the object to create a "bleed". how would I do that? thx. leaves.afdesign Quote Link to comment Share on other sites More sharing options...
Guest Posted March 5, 2017 Share Posted March 5, 2017 You can also transform the green rectangle into curves and modify its outline to fit the blue rectangle.But in principle an object with a transparency lets see what is below it. Quote Link to comment Share on other sites More sharing options...
Guest Posted March 5, 2017 Share Posted March 5, 2017 To eliminate the white line, do a "Add" Boolean operation with the two concerned shapes (dark green) that form this line. Quote Link to comment Share on other sites More sharing options...
gdenby Posted March 5, 2017 Share Posted March 5, 2017 Some perplexing stuff in the file. In the layer 5 object, add the 2 darker green shapes together. You will see that there are nodes that were made by the slight bug in the boolean. If the extra points that were at the center of the added objects are deleted, the thin ghost line goes away. But there are still transparency problems. I notice there are color swatches that are set to be partially transparent. Something I've never done. Don't know how that might affect the file. The stem and leaf items have me really puzzled. Everything seems to be set at 100 opaque. I messed around with the grouping, and the layer stacking w/o any results. I changed the items from pass-thru blend to normal.Eventually, I tried setting the stroke for the stem to none, and then bringing it back, and the stem became opaque as expected. Or, if I moved the objects and grouped objects outside the layer, and deleted the layer, they became opaque. Might be a bug. As mentioned above, transparency should let objects lower in the stack show thru. If you don't want that, but want a fainter color, change the color of the object.

kufloyd Posted March 6, 2017 Author Share Posted March 6, 2017 thanks for all your replies. reglico - that worked. gdenby - I think it's because I've applied transparency to each of the leaves. If I remove the transparency, the stem is opaque. I guess there's no way to have it be partially transparent and not have the stem show through. Like you said, I might have to choose lighter colors. It would be nice though if I could have transparency applied, as lighter colors aren't quite the same as a transparency gradient. Quote Link to comment Share on other sites More sharing options...
R C-R Posted March 6, 2017 Share Posted March 6, 2017 It would be nice though if I could have transparency applied, as lighter colors aren't quite the same as a transparency gradient. As others have said, transparency is the property of an object that allows other objects to be seen through it. Unless an object is totally opaque, whatever is on the other side of it will be seen. The more transparent it is, the less its color will affect the color of whatever is on the other side of it. Consider for example real world examples of transparency like clear or brown glass bottles; tinted sunglasses & goggles; colored gels; automotive window treatments; white, red, or rosé wine; & so on. So in effect, you are saying it would be nice if something could be made transparent without making it transparent.

Is it the gradient effect you want, rather than the transparency? If so, you might like to experiment with (100% opaque) gradient fills.
