GIMP :: Add Angle Measure Lines To Image
Feb 6, 2013
I use it to measure angles of micrographs (images taken with a microscope) --- the angle measure tool is great, and easy to use! I would like to be able to save the angle measure "rulers" into the image, for documentation purposes. Is there a way to incorporate the angle "ruler" in a layer or overlay in the image so that I can save a new file with the ruler "burned in" (for lack of a better term).
I will also be adding the text of the resulting angle measurement --- it would be cool if the result of the angle measure could be automatically added as text to the image (preferably in a different layer than the original image). I can type it the result with the text tool.

Several people recommended DIMANGULAR. I have some concerns using this method because it is dependent on the precision of angular units in the drawings DIMSTYLE settings. For example, if a drawing file's DIMSTYLE has a precision set to the nearest whole decimal degree or only shows degrees and minutes but not seconds then the angle may appear at a certain angle, let's say perpendicular at 90 degrees. But in reality the angle might be slightly less than 90 degrees, if its off by a few seconds.
I learned an alternative way by selecting both lines and typing the LIST command. The Angle in XY Plane will show the measurement for each segment in bearings, not azimuths. I simply find the difference between the Angles in XY Planes for both lines to determine the angle. I have a few concerns with this method.
1. How do you add subtract bearings measured in degrees, minutes, and seconds? For example, N 76d3'18" W and N 13d56'42"E? I "think" there are websites that can do this? Can this be done directly in AutoCAD through QuickCalc or some other tool?
2. Lines, but not polylines, have Angles in XY Planes in the LIST command. Is this because AutoCAD assumes that polylines will be composed of more than one segment (and each segment with a possible different angle)? Is there anyway to measure the angle of a single one-segment polyline?
Is there a DIFFERENT way between the two methods I just described to measure the angle between two lines (and two polylines) in AutoCAD?

I have Photoshop cs6 extended addition and was told Photoshop would work for the research application I need but so far I am finding it very difficult to do what I want. Basically, I need to be able to measure multiple lines (the red ones in the screen shot) of an image precisely, and make sure that the lines I measure are documented so that they are actually visible (so not just with the ruler tool) on the screen and labeled.
See image for example. I need the lengths (converted with the 2 micrometer scale at the bottom of the image). When I use the info, it gives me the lengths, but I can't save them, or look them up at a different time. Also, when using the line tool, then doing the "record measurement" it does not give me the length of the line but insted acts like it is a thin rectangle and gives me a height (which does not seem to be the same as if I used the measurement tool and put it next to the line, which is an idea I have, but not as accurate) and a width.

I am doing takeoffs from a CAD drawing. Without getting too deep into it, I have one origin point, and then I have 200 or so points around the origin. I'm trying to find the fastest way to get the X offset, and the Y offset between each point and the origin.
Right now I'm drawing two lines to connect each point to the origin, then using PROPERTIES on the lines where they meet to get each length - I need to be able to see the numbers on the screen for a second while I copy them into a database. But I'm wondering if it would be easier to write a script, or if there happens to be a tool that could do this with fewer clicks.

Nobody never thought into the needed of simply use three any points.?

i am doing a simple project making a survey plot for a piece of land that will be broken into subdivision. all measurements are of my starting point. after plotting the starting point i try to draw line that is 113 feet long and at a bearing of N 5d W i have no problem entering this data but when i hit enter it draws a straight line. now i know 5 degrees is much of an angle so i thought maybe it just looked straight and tried to plot the next point which was 542 feet from the last point at a bearing of N 39d E but once again after i put the info in and hit enter or space it would plot a line of the proper length but vertical, not the proper angle i need it at. here is how i would put in the info:
first i choose the lne command and choose my "beginning point" as that starting point for my line then i type 113<N 5d W for the length and direction and hit enter. when i do this it plots a vertical line of the proper length but wrong angle. what am i doing wrong? i have ortho set to off and idk what else to mess with

I was wondering if it is possible to measure the total length of lines I have in one layer without using the measure tool on each individual line. In searching other posts a lot of answers reccomend using LISP. Since I am not familiar with LISP at all and haven't purchased the add on is there a simpler way using AutoCAD LT?

I have been working on this for hours and have watched a ton of tutorials but I'm still not getting the effect I want with my image.
Is it possible to clean up all "sketch" lines in this image, leave just the skull (with teeth) with smooth and dark lines. I want to turn this into a logo.
I can make this image black and white then quickly get rid of the red. I'm just looking to get rid of the gray sketch marks and make it all one solid black outline while keeping the lines the thickness they should be as to not alter the picture.

So I am creating this website, and my customer wants a header banner similar to this:
(I don't know if it's clear enough, but there are multiple lines going through the image, with different gradient colors and so on)
Now I can't use this image, since it belongs to another website, but I want to make my own. So, I have no clue about how to make these lines in GIMP. I know GIMP's interface very well (been cropping, coloring for years), but not advanced features like this.
And it's not only the lines, but also the shadowing/coloring in between the lines that I seriously have no clue about how to make.
What is the tool called used for making this? Is there a video tutorial on how to make something similar?

Basically, I am trying to process a simple drawn map that was scanned and saved as a PDF. The scanned image is old so the paper is yellowed and they scanned it in high res color even though the image is black and white (well, blue ink actually). I just want to make the background white and change the blue/black lines to solid black lines that retain their clarity.
Here is a portion of the image:
The left is the original and the right is what I WANT, but cannot, achieve.
My biggest issue has been pixelation of the lines. I just can't get it smooth like in the right image. I've tried all sorts of filters - blurs, smooths, sharpens etc.. Part of the problem is also the degradation of the image after I extract it from the PDF.

I am unable to use the measure tool. When I use it, the distances and angles keep adding to the last reading and these cumulated readings are of no use.

II am looking for two things...
1) A good explanation of Vector3d. I have been unable to find a good explanation in the ARX documentation or on the online .Net developers guide.
2) Need getting the angle between two lines. The lines in question are in an orientaion similar to the greater than operator ( > ). I have attempted to use the Vector3d.GetAngleTo method to get the angle, but I do not understand it enough to be successful!

I know we all love the measure tool, but if you want to stroke with it what you are measuring in a certain angle you can't do it. At least nothing that I know of. How do you trace your angles with measurement (whether degrees or radians)?

I am trying out this option, and am noticing that whenever I close and reopen the drawing with a surface that uses this option, it resets my maximum angle from whatever I have it set to, to 90 degrees. Am I missing some setting that defaults the max angle to 90 degrees on drawing open? Or is something else going on here?

I want to "Fillet" a round angle. If I set the radius and then click the 2 lines then Autocad comes with the message: "Lines are non Coplanar" This problem just started in a drawing i was working in ( 50% were already done by Fillet perfectly ) , I draw only 2D.

i know DIMANGULAR command will let me draw a dimension to display the angle between two lines, but is there a way for my commandbar to show me what the angle is rather than draw a dimension?
I often want to simply know the angle but not display it in the drawing, and it'd be good if there was a command/lisp which showed me in the command line area, or perhaps a pop up window, similar to what the TLEN lisp does here: URL....

I have about 30 profiles with water pipe lines that I need to measure all their vertical angles. since the vetical scale is exaggerated so I can't use the acad angular icon tool bar. Only thing I cant think of is to block each run then import them back in at 1/10 in y direction. How to get this done faster or more direct by any other methods.

I am drawing a diagram to describe a mathematical word problem. Since it is easier to visualize with a drawing, I want to draw it using the given dimensions. But angles used in the diagram are unknown and are not needed for the answer to be calculated, so the only way to draw this freehand is to guess at the angle resulting in the correct distances to be off.
Here is the word problem: There are two ladders, one 40 feet and the other 30 feet, each touching the base of one of two buildings and leaning against the other building. If the ladders cross 10 feet above the ground, how far apart are the buildings?
So for my drawing, being rather simple considering what AutoCAD can do, results in this:
Can AutoCAD calculate the angle needed to place a line of a given length between two parallel lines that are a distance apart less than the length of the line to place between them, having the endpoints of this line touching the parallel lines, fitting exactly?
For the word problem, the distance between the two parallel lines is what needs to be solved and the math is quite invloved, having to find the roots or solution of a quartic equation. (I have the solution figured out to be 26.03287754 feet)
What I am afraid of is that this would require to program an AutoLISP routine to create a new command that one can call from the command line. I see it using the the measure command with relative and absolute co-ordinates. This may be far from a "beginner" question. I can do this quite easily on a peice of paper: having two parallel lines drawn, take a ruler and placing the "0" mark on one line, then adjusting the angle until the desired length just reaches the opposite parallel line. I used to use this trick quite often when drafting with pencil and paper to divide a distance into a required number of even amounts, so this can't be that difficult to do with AutoCAD!

It's not efficient to have to stop and change the angle of the tool for every stroke -
