How can i select areas of an image and find their size in pixels?

I have cs3 extended. Is there a tool ( i can't find one) that will allow you to make a selection and then calculate the pixel area of the selection? For measuring areas in a scientific application.

Measuring pipes lenght is quite easy with qselect + tlen.lsp, but, so far, how to measure ducts area quickly.
I'd like to add that ducts surface seen in 2D would satisfy me and i only talk about 2D drawings.
How to do this measure? Maybe there are lisp routines that could work?

Though, when meassuring areas (command area) even setting units to meters it shows: "Area = 0.00000073, Perimeter = 0.00343123" which is not expressed in meters. The area in meters is around 8900m2. We are using latitude, longitude LL84 (WGS84). Is there a way to easily measure area over the map using this coordinate system?

Closing and reopening AutoCAD doesn't work. It seems to be a permanent thing to the affected drawing.
It's happened to me in a few drawings, but only in those specific ones. Other drawings are fine. I'm guessing it's a setting I've changed somehow?
I've been getting round it by creating shapes using the polyline, and then looking at the area in the properties window. It's an ok solution, but not ideal.
Is there an 'easy' way to see a cross sectional area and measure it? I have tried getting a cross-sectional area by off-setting a work plane into the model, sketching on that plane, and pressing F7.
This shows the cross-sectional area, but when I click the inspect>area I can not select the cross-section. Any thoughts besides creating a sketch on that surface and extruding it to remove; taking the area measurement, and then undoing the extrusion?
I’d like to ask how I can measure the area of a region, defined on a TIN surface. ( i.e. the area of the bounded topographic terrain )
View 8 Replies View RelatedI've figured some things out, but am struggling with what appears to be a very valuable tool... the area tool.
I found many references to the boundary tool, but that looks more complicated.
I have figured out how to mark the corner and press enter, but the output is for example 1.7 sq ft vs. what should be approx 35K sq ft.
I tried to change the units, but that didn't seem to make a difference.
I'm wondering if there is a lisp possible to measure area's by pick point (as in bpoly). This little feature exists in Microstation so i was looking for something similar.
Is it also possible if this lisp can measure areas from an external reference (dwg, dxf, dgn, shp etc..)? I'm kind of new to AutoCAD in that sence.

View 9 Replies View RelatedI was wondering if anyone knew a way of determining how many pixels are selected (like with the freehand selection tool).
My problem is this: I have a map and I'm trying to determine the area of different countries on the map. The best I've been able to do so far is to draw a rectangular box around the countries and look at the width and height of the box and use the scale (so many pixels == so many miles) to figure the area. But some of the countries are quite irregular in shape and I'm just wondering if there's a better (more precise) way. I'd love it if I could just freehand select a country and then click a button to see how many pixels it is.
i wish to define a selection, which can be altered while preserving it's area.
for instance, assuming the selection is 6x4 (an area of 24), then any of the following selection box holds: 1x24, 2x12, 3x8, 4x6, 8x3, 12x2, 24x1.
is there any way to achieve it?
How can I keep my selection area on the background image or layer after doing a create new layer via copy?
I am trying to make a selection and an inverse of the selection and put each on a seperate layer to do adjustments seperatly without having to go back and reselect the desired area. It seems to disappear after the new layer is created.
Is there a better way to accomplish this, what am I missing?
Recently started experiencing a problem in PSE11. When I select an area of an image using the rectangle or lasso tool, the area I've selected immediately fades to black. Modifying the selection area makes it visible again for just a moment, then it fades out again. I know that the underlying image is not affected, as I can apply edits (filters, etc.), and the image returns to normal when I deselect. However, this is making image editing difficult. I'm on a MacBook Pro, running Snow Leopard (10.6.8). I also use Lightroom 4, and have PSE set as the external editor.
I uninstalled and reinstalled PSE, which worked for a while, but the problem has returned.
I want to select an area of video and use a filter on it but maintain that filter all through the video. Currently when I try to use a selection and a filter (blur filter) it will only let me effect one frame at a time. The one frame is under the affected video area. How do I extend that one selection and frame all through the video clip?
View 2 Replies View RelatedI use Photoshop to design interfaces and then cut down the graphics, by using the rectangular marquee tool and selecting the area that I want to save, copy-merged and then paste into a new document, of the correct canvas size according to the selection area, and then save for web..I end up with dozens of open windows all "Untitled" something, unsaved.
All I want is being able to select an area in my document using the marquee tool and then select from File a save function like "Save selection for web and devices...".
Perhapse this option could be in the "Save for web and devices.." dialog, where you could select from a dropdown the following:
"Entire document" (default)
"The entire selected area"
"Trimmed down selected area"

View 1 Replies View RelatedWhen I use the Fuzzy select tool or the select by colour tool, how can I remove the selection area around the parts that I don't want selected. For example. I have red car on a white background which I want to cut and paste to a black background. I select the white background, but although it selects all the white, it also selects other small areas on the car which are a similar colour. If the threshold is lowered too much when I use these select tools then I get a very small white border around the object when I paste it on to a dark surface. So instead of selecting using the default (15) or even less, I have to ramp it up so as the selection is closer to object and does not show the white jagged line. I thought that I could use the other selection tools with the "remove from selected" option selected, but each time I place a rectangle around the selected area that I want ot deselect, it does away with the entire selection area. I just cannot get it sussed.
View 4 Replies View RelatedWhile I'm in the "selection" mode - and it doesn't matter whether I'm preselecting objects or selecting them under some command - I pick the starting point of selection window and then I pan to another side of the drawing and there I pick the point to close the selection window.
Result: all the objects that I left behind while panning to the other side of the drawing, go out of the selection, so only those objects in the final viewing area stay selected - and it's not what I want... I want to keep all the objects under selection - including the ones that were panned out from the viewing area... I hope you understand what I'm trying to describe here....
I'm quite sure that this worked fine in previous versions, so I'm also pretty sure that there must be an option or parameter that controls my issue - I just can't seem to fint it...
How do I combine a fuzzy selection area with a dodge or burn operation?
The fuzzy select tool is handy for roughly outlining areas of over or under exposure. There must be a way to combine an oddly-shaped fuzzy selection area with a jittery dodging operation. Do I have to turn the fuzzy selection area into a "brush" somehow, in order to "dodge or burn" that area?
When using the LR5 spot removal tool I can perform cloning or healing and LR automatically selects the target used to clone from, but I cannot see where this area is on the image. A pin should appear with a line connecting the area to be removed and the target area used to clone from. I see no pin. Is this controled by a setting?

The problem is that if one has defined a selected area in an image, using either selection by color or contiguous selection using the 'magic wand' facility, is possible to copy this selection to the Image Map facility of the image, so as to automatically define a set of coordinates as a polygon that can be used for link purposes? Perhaps there is some interim step that is required, or perhaps a special script is required?
View 1 Replies View RelatedI want to select part of an image with just one layer. Say I just flattened the image and have to move one part of. I select it with the rectangular select tool. It seems intuitive that I could then just move what I selected, but when I drag the selection, the selection itself moves without moving what is inside the selection.
If I then remember to click the move tool and try to move what's in the selection (seems to work sometimes, maybe when there's multiple layers?) the entire image moves.
The only way I can move part of the image over is if I make a selection and then cut it (ctrl X) then paste it.
How am I supposed to move part of the flattened image, is there a way I can set it to default to "When I select something, I can immediately drag that selected area around."
I've recently migrated from AutoCAD 2008 (non-industry specific) to AutoCAD 2010 so I don't know if this was an issue in 2009.
Back in 2008, when I choose the 'window' option when specifying a plot area, AutoCAD would show the workspace so that I could manually select a windowed plot area, and at the same time the whole workspace would be greyed out except the previously active window area.
This was handy, because we can have as many two dozen title-blocks (and therefore separate viewports) in paperspace, and knowing what plot area I last plotted or added as a saved page setup.
In 2010, it no longer does that. I now have to rely on the dashed border to know where the active plot area is/was (checked 'display printable area' in options>display tab) which I personally don't really like using.
How to changes the settings for the "Square Area" in mapcheck's closure summary. When I right-click the dwg name in the Settings tab of Toolspace and choose Edit Drawing Settings, then Ambient Settings, I see the Area settings, but in the closure summary, there is also "Square Area". Why are these both there? It WOULD be nice to show sq. ft. as well as acres, but I can't find anywhere to edit it.
