Photoshop :: Compare Number Of Pixels Or Diameter Of Objects Across Images For Each Of 10 Objects
Apr 15, 2013
I am currently selecting 10 objects from a picture and then I delete the background. This leaves just the 10 objects of interest in the image.
I have hundreds of these images and would like to compare the number of pixels or diameter of the objects across the images for each of the 10 objects. Is there a way I can automate Photoshop to go through a directory of images and measure the pixels of each of the 10 objects, and then export those measurements to a file?

I'm working together with a photographic studio in order to study better ways to cut subjects in their photos. So, instead of using the ways we use to cut. We have taken 2 photos for the product. The first is only the background, and the second is the beackground with the product. Look at the attachments in this message. It's a simple example (not taken in the studio, with control of lights and so on, but should work for testing purposes).
Looking at the 2 images, you can see the bottle and his reflex or shadow is the unique content that changes between the 2 scenarios. If you try, for example, place each file as a layer, group them into a smart object then use stack modes, you can take off the bottle from the scenario. We are trying to find a way to get the inverse (leave only the bottle). So, if finding any combination of technique that works, we could speed time in the cutting process by already taking images this way.
(perhaps a combination of blending, use of channels....), anything that could compare the 2 images and calculate the different pixels (this case, the bottle)? or perhaps reach an alpha channel that makes easy to perfectlly cut the image.The difference blending mode, for example, makes a calculation of pixels, but I did not get so much sucess working based on this blend

Somehow I must have activated an option to only be able to move any object a certain distance at a time. For example, I have a circle that I want in a certain position but I can not move it there with my mouse. Instead it insists on moving 18,9 pixels in any given direction whenever I'm moving it with my mouse. To get a specific position I have to enter its position manually.

Illustrator has the 'Transform Each' dialog, but it only allows you to scale multiple objects by specifying a percentage. Is there any way to specify the size in pixels? More specifically, imagine I have 10 rectangles on my canvas, and I want them all to be of a specific height. The rectangle position on the canvas matters, so I can't do the 'vertical align to top and then resize group height' trick - they need to be resized in place.

Somehow I've managed to disable a feature in Illustrator CS6 that does two things: 1) it causes a small box to follow the cursor when I'm drawing an object 2) the light green lines or x's are gone now, too. How can I get them back? Are they only visible under certain circumstances?

is there any way to schedule objects by id number?, maybe through a formula within the schedule that may call the id or the revit API and if that is the case

I have some code in a VBA program I'm trying to convert to .net that loops through all the entities in model space as in the code snip below. What I can't figure out is how to get the total number of objects in model space at the start so I can use this info to advance a progress bar. ie the equivilent of VBA's "ThisDrawing.ModelSpace.Count"
Dim bt As BlockTable = tr.GetObject(DB.BlockTableId(), OpenMode.ForRead)
Dim btr As BlockTableRecord = tr.GetObject(bt(BlockTableRecord.ModelSpace),
OpenMode.ForRead)
' Loop for each entity in the modelspace
For Each entId As ObjectId In btr
'<code sniped>
'advance progress bar
Next

I've got a large job and Object Isolate has been good for our drawing prodeuction but now we're running into some glitches on a regular basis the last few weeks.
1st Undo is being disabled. Thia really only started since we've begun plotting drawings and Isolating objects.
2nd We can't isolate everything. Is there a limit to the number of objects that can be isolated? or anything that controls that?

why a drawing would open without a number of objects (text) showing? I open it up and all notes are gone, yet another user opens it up in "eDrawings" and it opens fine. Oddly, when in ACAD I click OPEN, the preview ACAD gives me when I click this file once shows the missing text etc. But when I open it they're missing.
Below is a screenshot of firstly the drawing open in ACAD and secondly open in eDrawings.

I was wondering if someone could help me with something that is really starting to annoy me.
When I'm moving objects in Photoshop, I find that they sometimes "jump" across pixels when I'm moving them.
For example, lets say I've got an image and I've zoomed in so that each pixel is shown as a large square. The rightmost edge of the image is on column 1 (bear with me).
Each column is 1 pixel wide. So it would look like 1 2 3 etc.
The rightmost pixel of my image is on column 1, and I want to move it to the right so that it is lined up on column 2.
I move my image to the right, but it doesn't land on column 2 at all and skips it, to end up on column 3. So I move it left and it again jumps column 2 and ends up back on column 1.
I hope this makes sense.
I've experienced this on Photoshop 7 and CS2, on 3 different computers. I used to experience something like this in Microsoft WORD during IT classes at school years ago. We had to go into a menu and uncheck something to do with grids, but I can't remember exactly what to do, and I can't find anything that looks familiar in the Photoshop menus.
I really hope this makes sense to someone, because it gets incredibly annoying when I'm trying to be precise.
Sometimes zooming in to 400/500% stops it, and everything moves smoothly, but it doesn't work all the time.
It doesn't always "jump" one pixel either. Sometimes the "jump" can be 3 or 4 pixels wide.

I am looking for a way to extract (filter) all polylines, and loop a lisp based on the number that are found within a "W" selection window.I am frustrated getting "malformed list" or errors, even after defining "n" for repeat.The code I have so far looks like this:
(defun cWW (/ p1 p2 sspw myObj ss)
(setq p1 (getpoint "
Pick first corner: "))
(setq p2 (getcorner p1 "
Specify opposite corner: "))
(if
(setq sspw (ssget "W" p1 p2 '((0 . "*POLYLINE")))
[code].....
Without the (repeat () portion, it was working ok with selection window, however it only would run the commands for a single polyline. What needs to be done without overhauling the code? The lisp has worked on a drawing-wide basis, however needs to run on only on user-windowed polylines since there are other polylines within the drawing which are attached to layouts via viewports.

I am very much new to AutoCad, but have learned quite a bit about it in the last few days. As a part of the learning I have been building a 3D model of the shed my dad is building. But I ran into a problem on the roof and cant seem to figure out how to click everything into place.
My problem: I need to keep the size and shape of all objects while also connecting the objects to the main structure. I need to keep A and B connected to the main structure and adjust the angles so that both meet at C. But if I move one then another moves out of place. (In the pic B is out of place) All I want to do is hold the beams at A and B in their spot while adjusting the rotation on both beams to meet at C all at the same time. I have tried to fine adjust the rotation on the beams individually but still cant get them together. I cant seem to get the constraints feature to work, because I guess it only works in 2D. I have tried to use the align tool but it just throws everything haywire.

How does one remedy this Adobe error message? "Can't scale the objects. The requested transformation would make some objects too small to use." This one always gets me. I'll spend more time trying to find the object in question. This has happened in almost al versions, but this time it's CS5.

I often produce graphics in CorelDRAW, export it as en eps file and insert it inside a MS Word document as an image and finally convert it to pdf. This way my vector graphics (often linedrawings with or without fill) usually is preserved in the final pdf document. I can zoom in and the lines keep on displaying perfectly sharp. This is important, since it easily looks bad when thin lines are turned into bitmaps, even when watched from a distance.
Now, in some graphics I created today, I had a circle with fountain fill and outline (symbolizing a sphere) put behind a filled rectangle, which had a uniform transparency applied to it. In the resulting pdf file, the 'sphere' was turned into bitmap. Inside CorelDRAW everything was vector graphics, but something was loast in the process. what happens with the graphics in the different steps in the process and eventually could explain a workaround to make everything look as vector in the final pdf file.

I have several .dwg files that I use as templates. I run find and replace VBA routines on the template .dwg files, ie find $Flavor$ and replace it with "Grape", and then I save the .dwg to another directory with a new name.
These VBA routines work well for acdbText and acdbMText objects, but I have a bunch of AcdbAttributeDefinition objects in the .dwg templates as well.
After much research about the AutoCAD object model (I'm mostly a Microsoft Access VBA programmer), I have come to understand that these AcdbAttributeDefinition objects are actually "remnants" of a block that no longer exists in the drawing.
Anyway, I'd like to convert all of these orphaned AcdbAttributeDefinition objects to acdbText objects in the templates and then delete the AcdbAttributeDefinition objects. I have some code that does just that.
However, the issue that I am having with the code is that the newly created acdbText objects are not on the same layer that the original AcdbAttributeDefinition objects were on. I don't know the syntax to identify what layer the AcdbAttributeDefinition object is on or how to specify what layer on which the acdbText object is created.
how to keep the acdbText objects on the same layers as the original AcdbAttributeDefinition objects during the conversion and deletion process?
Here is the code I am using currently:
Sub AttConvert(dwg as string)Dim oDocument as AcadDocumentDim ent as AcadEntityDim aa as objectset oDocument = Documents.open(dwg) For Each ent In oDocument.ModelSpace If ent.ObjectName = "AcDbAttributeDefinition" Then' DO SOMETHING TO IDENTIFY WHAT LAYER THE ACDBATTRIBUTEDEFINITION OBJECT IS ON
' DO SOMETHING TO SPECIFY THAT THAT IS THE LAYER TO CREATE THE ACDBTEXT OBJECT ON Set aa = ThisDrawing.ModelSpace.AddText(ent.TagString, ent.InsertionPoint, ent.Height) End If Next ent For Each ent In ThisDrawing.ModelSpace If ent.ObjectName = "AcDbAttributeDefinition" Then ent.Delete End If Next ent End Sub

I'd like to know how to align an object in model space with the edge of my viewport in paperspace.
When I draw, I like to lay out multiple complete drawings in model space, make an appropriately scaled bounding box around them, and then snap a view port to the bounding box in my layout. I usually have multiple drawings lined up in a row in modelspace, so when I want a new layout I do a Save As and then pan around in my viewport to find the next bounding box, at which point I have to resize the viewport to get it to snap to the edges nicely. I really want to be able to to it the otehr way around- while panning I'd like to be able to grab a corner of my modelspace bouding box and snap it to the the corresponding corner of my viewport window. That way making new layouts would be a snap. Is there a way to do this in AutoCAD 2012 LT?

A user is having problems when using the copy command in AutoCAD 2013.
When they select objects, its not reporting on the commandline how many objects its found or keeping a running total of objects selected. Not even any duplications...
I've tested it on my machine but i cannot replicate the issue and have never come across this before!
Is it a bug? Is it a variable? User setting etc.

I'm used to open my photos as smart objects. So I open them in Camera Raw, edit and open in Photoshop CS6 as smart objects.
My issue is:
In CS6 when I double click the photo and open it again in Camera Raw, I can't find a way to save the edits. I mean, if I close the photo in CS6 and open it again, Camera Raw keeps only the edits I made the very first time I opened the photo.

so I'm working on a pretty complex image with alot of composites - models on a new backgrounds, new heads, arms, etc. I had to scale these elements down to fit the image and I used smart object b/c i had to go back and forth and get placement approval before moving on to the retouching. I still have to adjust the mask edges in the smart object PSB's but it is really annoying to go back and forth from the composite image to the PSB with layer mask. Is there a way to rasterize the PSB into the final image with the layer mask so I can better blend it? I tried dragging the PSB with layer mask over but of course it is too big (because i scaled the PSB down).

how to edit revit objects in 3dsMax. How do I separate objects to make them individual objects? In other words, when I try to select the roof, I get ALL objects that are "dimensional lumber" i.e. I joists, roof, fascia, etc.
I tried selecting a roof polygon and making a copy and editing it but still when I apply materials to this polygon they apply to all of the dimensional lumber. Probably because I made a copy as a clone but it didn't give me the "copy" option.

There are 3 elements there. the top of the clap board was placed before i started tryinbg to create the slanted dashes that are on the average clapboards. The white dash was skewed using Object > Transform > Shear. Then i attempted to rotate it to fit.
I need 4 of these skwed white squares / trapezoids on the top along with 4 to match on the top of the larger potion of the clapboard. I do not want to eye it as it will be a part of a logo.
What would be the best method to use?Is there a way to draw the 4 rectangles on top of a perfectly horizontal long black rectangle and skew the white dashes at the same time?Is there a way to skew based on the dimensions of the longer black rectangle?
