Thanks! Yeah I was using CAD software to measure and trace lines. What I ended up settling on was using the blackened lines and looking where the straight edge starts to deviate at a corner and then measure the distance to the other perpendicular lines corresponding edge at that corner (note: the image below does it for the middle of the darkened line). The "eyeballing" of corner round tangent points to a straight line is one problem but I thought there maybe a better way which is a less subjective and more repeatable proceedure. A larger photo of each device would help a lot but that isn't available.

This is a image of an integrated circuit die. Notice that there are (almost) black lines bordering differently doped regions of semiconductor devices (transistors, diodes and resistors) with silver colored metal contacts and interconnects. What i would like to do is extract only these "black lines" and just "white out" everything else. If you look close at the corners of these lines you see they are rounded. Secondly, I would like to measure the radius of these rounded corners and if anyone knows an easy way to do this in software please let me know. Corner radius size is what I ultimately want because it varies with diffusion depth of dopants in the various n-type and p-type aspects of the silicon.

To bad about the PDN. I would imagine that even a limited enlargement would still help in a lot of cases. Anyway, thanks for your update and look forward to using the upgrade.

Great! Also notice that when i skewed my original picture, the plugin did not enlarge the size of the resulting image automatically but instead cropped off parts of the curves on the right. Maybe an automatic enlargement option would be handy. Thanks.

Addendum to my last post. I forgot to mention a request that would be helpful to control skewing. Would you consider a skew angle input since your slider scale doesn't seem to be in degree/radian units and allows decimals for finer control of angles? One could skew these curve traces to a better precision needed to extract data points from the curve with extraction software (e.g. webplotdigitizer) that is orthogonal axis based. There are probably other use cases besides this but that is currently mine. Thanks.

I had to uncheck your "Fine control" to get the extent of horizontal skewing i needed. Here are the before and after pictures. For example, the red dots should be vertical and all at the 2e-17 V/NBC value afterwards.

Hi Boltbait. Could you please extend the range of your skew plugin. Having a skew angle setting would be helpful. Consider the attached image. To horizontally "de-skew" this chart one needs more range than what your plugin provides. Thanks.

How do i darken and maybe thicken all lines in a line drawing? I need to darken the grey lines in a two color (grey & green) line drawing since they are hard to see. One way is a fill but there maybe some quick method that proportionately darkens just the grey pixels while preserving the relative grey gradient between grey pixels. Thanks.

Zipit, is there a way to smooth/curve out the husbands left elbow? The picture was cropped there leaving a straight line at that location.

Thanks to everyone. This link and the other comments helped a lot. I like the method of using the pencil or brush on a transparent over layer.

I've used a "threshold" tool that comes with one of the plug-ins to blacken out backgrounds that I wanted removed from a photo. The problem is that this doesn't work well or easily in general and I would appreciate help with techniques to deal with photos like the one attached. In this photo, I want only the family/people without the back ground of the house (etc). Thank you.

It's for the web so no choice. But I found a work around. I saved the .JPG image as a .BMP file then opened it in regular Paint that comes with Windows. From there I saved it as a .JPG and it now works fine with FF & IE. Originally the problem occurred when saving the image as .JPG or .PNG from Paint.Net One file format worked in one browser but not the other. The reverse happen when I changed to the other file format.

The following png file causes IE8 to render the blurred image with a black back-ground in the portions of the blur between the original shape which sharply ends at the transparent areas outside the blur region. This image shows up correctly with the black background sections transparent in Firefox 3.6. How can I fix this?

Thank you and I will give that a try. Also, did you see my problem I'm getting in this thread?

Here is how it looks when I open my web page in Firefox. In IE8 the image blends perfectly with the background. How can I fix this? Thank you.

I have the background image and foreground image attached. The female is in the foreground image who's left/right edges don't match the coloring of my background image. This causes a line to show when one is on top of the other. I tried using the gradient tool but can't quite get the left/right edges to smoothly blend with the images below. What do I do? Thank you.

Your technique works very well. I've attached the image. However, the color is way off in Firefox 3.6.8 but renders perfect in IE8. Why would that be?

By the way, what plug in are you using. I don't have effects like "Threshold" and the plug in by that name does appear the same on the plug in download page. Thank you

Sarkut that is very nice and I appreciate the effort. Thank you. I figured out a rougher approach yesterday that did not work as well. Also, I'm not sure these images are done with silhouette blurs. It maybe just some circular or ellipse white object that gets blurred and sits in a layer between the image and background. I've attached some more in a set I have and lastly the one I did which I will redo by your method. What do you think they are doing? Thanks again. <one image removed by EER>

There are three images attached. 1. Two people standing back to back with business information. 2. A background image for 1. 3. An image of a person holding their neck & back with a black back ground I would like to make another banner just like 1 but with the image found in 3. This new banner should have the same back ground as 1 and the same halo/glow effect as in 1 but around the single person in 3. Thank you for the help.

Is there a way to get 3d effects as in the following YouTube video: The images used can be found on Google Images but they are being "twisted" and distorted in 3d. Does Paint.net have this capability or do I need another tool ... preferably free. Also, there is a 2D effect where an image is blurred and then moved around. Again, is this something for paint.net or better left for another tool? If Paint.net is adequate then I was going to import the images/animations into windows movie maker. Thank you.

Never mind

Thank you welshblue & sarkut.

Best to look at the image but basically I have some subtle circular rings in a photo of two people and I would like to keep the photo but have these rings disappear. I don't know what fastest or best way to go about doing this. Can anyone help. The image is attached
