Lightroom :: What Are White Point Coordinates Of Melissa RGB
May 28, 2013
As there is some confusion with the colorspace used with the Sigma SPP software when creating so-called "ProPhoto" 16-bit tiff files for the Merrill-based sensors cameras, and I am contemplating using Lightroom just for LOCA correction, as some seem to imply it works well in comparison to the SPP 5.5.1 equivalent corrections, I'd like to confirm that Lightroom's expectations in terms of photometric interpretation(s).
1) D65 illuminant ==> what are the white point coordinates of Melissa RGB ? (Plankian ?)
2) Gamma ==> is it sRGB or gamma 2.2 or anything else ?
3) Can you elaborate on the metadata (EXIF & tags) used by LightRoom to get the Sigma Merrill SPP 16-bit TIF SPP format photometric data ?
4) What's the closest to Melissa RGB : ERIMM, RIMM or ROMM ?

i am trying to translate a Point coordinates from Paperspce to world coordinates in model space.The code i used in Land2006 worked OK but now in Civil3d 2012 it doesn't!
Private Sub GetPlais_Click()
Dim tmpnt1 As Variant, tmpnt2 As Variant, tmpPnt1 As Variant
Dim lole(0 To 2) As Double, upri(0 To 2) As Double
Dim returnobj As AcadObject
FrmGrid3.Hide
On Error GoTo Eline
ThisDrawing.Utility.GetEntity returnobj, tmpPnt1, "ÅðÝëåîå ôï ViewPort ðïõ èá äçìéïõñãçèåß ï êÜíáâïò!"
If TypeOf returnobj Is IAcadPViewport Then
[code]........

First time importing into 2012-have csv file that I imported. Coordinates land in right spot. Local system-No transformations/State Plane zones attached. When I look at them with tracking everything is okay. When I export the points they are the same I imported.
When I list the points they are way off?

In autocad 8, how could I get the XYZ coordinates of a point, on the drawing. With ID or list command it is possible to get the coordinates of a point, but they would not appear on the drawing the way dimensions do.

My quick question id for an alternative way of exporting a cluster of points as .shp files and then manipulating the .dbf file in order to create an excel/csv file.
Is there another way of exporting my data as .csv or excel from Map3D?

I use POINTCLOUDINDEX to convert .las file to .pcg file, then I use POINTCLOUDATTACH to add .pcg file to model space.
How can I get the 3d coordinates of points in .pcs files?
I use ObjectARX in .net.
I can't find any Entity types related to pointcloud, should I find in other namespace?

i've got a bunch of points that need a coordinate label. my drawing is on a state plane coordinate base but i want the point labels to be on an artificial coordinate base. i basically need to start in the corner of a parking lot at 0,0 and work my way out from there with the coordinates based on that 0,0. Is this a possibility?

I have a drawing which consists of lines and blocks. I need to write down the (x,y) coordinates of each point of my interest. I expect results to be copy-paste'able, text or plain text preferred.
How should I do that? I guess there is a build-in command for this, I fail to Google it though.

After creating an extrusion, we selected the object sometime later, but are not able to edit the vanishing point coordinates for the extruded object. Is there a reason we cannot edit this object?
Vanishing point coordinate boxes, on toolbar, are grayed and unavailable.
Anchor for vanishing point on drawing screen is an outline and unavailable.
Object is marked as editable, so editing is not blocked.
Selecting the original text or extruded subgroup object makes no difference.
Extrusion gradient colors are not showing on the extrusion walls.
Have varied the 'Extrusion Type', but the types are hard to discern and don't make a difference in the editability of the object.

How to truncate coordinates in a C3D point table?
My situation is that I have ground coordinates that are similar to state plane, but because they are not on the grid, they aren't exactly the same. I want to display the coordinates without the first two or three numbers, in order that people won't get confused and think that they are on the grid.

I'd like to know the coordinates relative to the last entry when creating lines (splines). When creating splines using the line tool, it would be useful to know the coordinates of my current cursor position relative to the last point in an easy way, so I can draw precisely a long line without having to memorize the coordinates of the last point.
Initially, I thought the 'Keyboard Entry" rollout would show the values that reflect what I'm doing visually, just like the rectangle tool for example, or pretty much any other tool, I don't know why the 'line' tool is different but anyways.

I have spent the last couple of hours researching posts back to 2008 regarding inserting inserting a point cloud into Revit at the correct coordinates. I have two files (DXF and PCG) that are in the same coordinate system. They overlay exactly in AutoCAD. Why I see posts back to 2008 with no resolutions on this same topic? Also explain to me why a file indexed in AutoCAD 2013 is not compatable with Revit 2013.

I have a problem with absolute and relative coordinate regarding drawing an arc.
From my previous studies, I thought whenever I input coordinates in command line, in order to use absolute coordinates I just enter them. If I want to use relative coord, then I can prefix them with @ sign.
For an arc I input as follows: start point: 0,0 2nd point: 500,500 end point: 1000,0. I was expecting to get a half circle from origin to 1000,0 point but to my surprise I find out that CAD gets the input coordinates as relative.
Am I missing something? 1.dwg1.jpg Is this behavior same for all other object drawings?

A way to automatically output a point into a table. For instance having a table searching for a specific block reference or point inside a block or external reference and submitting this into a table with x,y coordinates?
I make a lot of civil drawings and sometime i need to list up relevant coordinates. In stead of manually plotting these in a table i would like to list them up automatically.

Having trouble recently with tracking,For example if i start the line tool, and track from a point, i am given absolute coordinates instead of relative coordinates from that initial point. Absolute coordinates are not much useful to me, I want to be able to start a line at a certain distance from another point.

How can I automatically get point coordinates and show it in drawing. For example I have 100 points and I need to write x and y coordinates right next to the point. (not in table or somewhere else).I guess I need a plugin or smth?

I am trying to annotate a drawing so when i click on a point the X,Y,Z coordinates appear as text, but i don't want a cross to appear where i have clicked the point ( if that makes sense)
I would like for them to appear like this:
x = ........
y = .......
The coordinates would have to show to 3 decimal places.
Also when i have clicked a point is there anyway to get the coords into a excel sheet?

I don't simply want to see the coordinates when I hover over a point. I want the coordinates actually showing on the document. Is there a plug-in that can accomplish this easily?

I'm working on a stream restoration project and we need to determine the x coordinates and corresponding elevations along a stream alignment at certain sample lines. The centerline of the stream's alignment has been created as well as sample lines for cross sections at 50' intervals. We need the coordinates & elevations of each sample line (cross section) exported into an excel/txt document.
For instance, at station 1+00 of the alignment we have a sample line. We need to know to the right and left along that sample line the corresponding elevations and that x coordinate) from the alignment. Primarily, whole contour intervals but more information would be useful as well. I was hoping this could be automatically generated.

I am using illustrator cs2 and somehow my reference point locator is missing from my menu bar? Also, I am not able to manually set the x y coordinates on anything besides 0 0. I have been using this program for a long time and haven't had this happen before. turned off the reference point locator but I can't see where to get it back on my menu to be able to align objects.

We have several AutoCAD drawings with hundreds of block references inserted with imprecise coordinates. Now we need to dimension all elements and need to correct these positions.
I am searching for a routine to round these positions up or down towards a 5mm precision so I don't have to manually move every single block element.
Is there any way to automate the task or do you know any workaround (like inserting the elements into a drawing with poorer unit precision settings)?

I am tryiny to import coordinate file like I have so many times and the Select File box keeps telling me "No point file format match found". I click the proper file format and it shows in the Preview box but the OK box will not go dark so I can clcik on it. The file is a CSv and tried making it a txt with no luck. Using 2012.

I'm relatively new to AutCAD map 3d but I've used arcGIS a while back.
I have existing roads, towns etc data that are already set to UTM 17. I want to import ascii point coordinates (from a comma delimited file) into the file. I can import the ascii coordinates as points fine (easting and northing), however the points come in as the absolute coordinates rather than geometric coordinates. I already set the files for right geographic projections. Beyond manually inputing the coordinates into the coordinate tracker, is there a way to import the coordinates form the file set for the geometric coordinates?

I'm taking shots of some furniture I made. I get the shot all set up and the exposure correct for what I want, then I take an 'extra' shot with a gray and a white calibration card in the scene. Now I have two identical shots except that one has the calibration cards.
My question is: how to I select the white (and gray) levels from the calibration shot and then use that data to set the white (and gray) levels in the good shot. I had done this many years ago in CS3, but I don't remember the process.

I'm a GIS analyst trying to learn Cad. I'd like to place a single point in autocad model space at a specific Northing/Easting position. After reading several forum threads I don't think CAD allows me to change the coordinate system of model space from map coords to northing easting coords, as we can in GIS.

The coordinates that we can apply in Revit (project/shared) aren't exactly the same to have real world projection coordinates (WGS84)??
If not how can we convert the revit shared coordinates to real world projection coordinates?
