I need to understand how to calculate how many lenticular images I need to interlace if my printer resolution has 9600 x 2400 dpi and the lens has 200 lenses per inch? I think that I am doing a mistake using the manufacturers dpi resolution and that I should be using PPI instead?
View 9 RepliesI would like to use Photoshop to create accurate residual images (image describing the difference between two images) and to apply such residual images to restore one of the images used to create the residual.
given two 8bit images (pixel values in the range [0, 255]) a residual image would be created by subtracting one image from the other:
Residual = Image A - Image B
as the potential range of this residual is [-255, 255] it must be mapped to [0, 255] to be saved as image:
Residual = (Image A - Image B) / 2 + 127
given the residual image and image B, image A can then be restored as
Image A = Image B + (Residual - 127) * 2
so my question is: are these two processes (creating a residual image and restoring image A) possible using blending modes, and if not, can i program it somehow? I already tried it using Pixel Bender, but the Pixel Bender Photoshop plugin doesn't seem to work for pixel bender kernels that take two input images.
Can photoshop Cs6 do 3d lenticular in a range of Lenes like 100LPI or 75LPI?
View 2 Replies View RelatedI'd like to prepare and then print a 3d lenticular image.
View 4 Replies View RelatedAt work we're about to jump into this whole lenticular (3D / motion) printing business. (You know, like those 3D motion images which came in the Crackerjack Boxes).
The only software out there looks like it was designed in 1995 and is just as easy to use. Then I found a link to www.russellbrown.com where it's discussed that PS CS4 Extended offers this.
Is there any info out there which discusses this feature in PS Extended. 'Til now I've found nothing which describes it in depth; the features etc. Specifically, how many images can be interlaced, how it works and so on.
whether to upgrade to Extended or the Standard CS collection.

How can I calculate the size that text in Adobe Elements 6 will display on my monitor? I have set this visually so that it is approximately 0.2" on an image height of 6.6".
My OS is Windows7 Professional and my screen resolution is 1280x1024 pixels.I have cropped the image to 7x5 and resized it to 5290x3770 pixels (w,h). I have set the resolution to 571 pixels per inch. Placing the text at 17.3 pt gave me the 0.2" height I wanted on the 'Fit Screen' zoom.
The Display Option shown in the Control Panel is 'smaller' which I understand means approximately 96 dpi. I have read that points to pixels is calculated by: Pixels = Points * System DPI/72 giving 1.33 points per pixel. Thus the 17.3 pt text should be about 13 pixels high.
Thirteen pixels is 0.34% of the 3770 pixel high display which implies a text height of about 0.02" on the 6.6" high displayed image. Instead I am seeing a text height of about 0.2" (as required).
i created new polygon´s SDF (ACAD Civil,Map2011). And created new feature from geometry (from 2 closed plines - island). See on attached picture. If polygons are more complex =erroneous result from calculation ("Round ( Area2D ( Geometrie ), 0 ) "). It means ACAD calculate sum 2 areas together, but It should dedust island from main polygon.

View 9 Replies View RelatedWhy when Lightroom loads images (in develop module), all images turns gray and dark (the preview looks fine - expected exposure and full of colour). All settings are on 0, no auto tuning or presets are applied.
Also, when I take pictures (Nikon D4), they looks fine in my back screen and I would guess D4 knows how to calculate exposure. But in Lightroom they all come out at least 1 full stop unexposed, so after adjusting exposure I got unnecessary noise grain (and work).
I even tried to upload thought Nikon View NX (soft for Nikon transfers) first, as I was hoping that after importing files to Lightrooms I will also get camera colour settings (like Landscape, Portrait, Vivid, etc.).
This is screenshoot - when Lightroom loads/process all images they all turn so dark as selected image. Neighboring sunflowers all were the same, and they was as I expected them to be.. Before they turn dark...

View 9 Replies View RelatedI'm using AutoCAD 2013 x64 and VS2012 Express with ObjectARX 2013. Now I want to calculate the (projected) intersection point of 2 (intersecting) lines in vb.net
After selecting the lines I have this line1.IntersectWith(line2, Intersect.OnBothOperands, intpts, 0, 0)
In Visual studio express 2012 I get the following warning for the above line of
warning BC40000: 'Public Sub IntersectWith(entityPointer As Autodesk.AutoCAD.DatabaseServices.Entity, intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, points As Autodesk.AutoCAD.Geometry.Point3dCollection, thisGraphicSystemMarker As Long, otherGraphicSystemMarker As Long)' is obsolete: 'Use the overload taking IntPtr instead.'.
So, if I'm reading this correctly, this method is outdated and I should use an other method to calculate the intersection. But I really don't know what 'Use the overload taking IntPtr instead' means.
One of the things I found is a function that contains this line of Dim inters As Point3d = line1.IntersectWith(line2)(0). This one looks almost the same, but doesn't give me the warning when I compile the code, but this method crashes AutoCAD when there is no intersection between the lines. This is despite a try catch block that surrounds the code.
For now I just want to use lines, but I need to expand the code so it will also work with circles, arcs and polylines.

View 1 Replies View RelatedI'm struggling with the maths needed to calculate the angle between 3 points. My eventual aim is to use vba to draw a crescent shape polyline, ie 2 arcs curving in the same direction and joiing at their tips. Both arcs will have different centrepoints but the same radius. The only info I know so far is radius (R), centrepoints (CP1, CP2) and the intersection points where their end points meet (IP1, IP2). I've gotten those points by using the 'IntersectWith' function on two circles.
My coding skills are fine it's just the maths I'm struggling with and after searching google for quite some time I'm still confused. I've looked at loads of differnet formulaes and diagrams, but it always seems like they aren't complete. Maybe it's just me.
I have the testversion and i do some tests with Digital noise removal and a 10 megapixel Image and 0.3 megapixel image.
On my system, it happen that Paint shop wait around 4 sec and do nothing.then it begin to calculate and progress requester is show for around 1.5 sec
Can see when switch in task manager the CPU load refresh to high(4* /sec seem value update).when i choose a setting or i change a value it take always 4 sec until CPU load increase from idle % to full load.
I have also written a Bug report and suggest that Paint shop begin calc as soon as possible, and stop if a value is change and calc again soon as possible with new value.So all can work lots faster.currently i get no response.
The Smart Photo Fix, too have a delay before calc.It is 1 sec.I test with a 320*250 Pixel image (0.3 megapixel), here the additional delays are too in.
In the feature list X4 stand that it can use GFX Card to be faster.I have a gforce 6600 with older pixelshader.So i guess X4 use no GFX card.The render speed of all effects i think good, but the wait time make the usage of this program not fun. I think the X4 Version is great, very good denoise sharp and enhance photo functions.

View 1 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
How do you calculate paint area?
We do a lot of chutes (for mining). They need to be painted on the outside only. They also need to be lined with rubber sheet on the inside. The area given in the physical tab in iProperties is the total area.
The area of the edges of the plates are small enough that we can ignore them, but is there a way to calculate half the model's area and get that result in the drawing in a text note?
We've only recently switched over to Inventor (used to be on Solidworks, where we had the same problem).
