I am first time working on PDF documents.I was searching on Rotation of a PDF page. I got some code samples regarding rotations by 90,180,270,360 degrees.
But my problem is that if there is a very small rotation required of the order of few degrees .. Is there any way that we can specify an angle using a slider bar or use the mouse to click and rotate the PDF page...
I am having some major problems with the code in VBA and recording a macro didn't get me anywhere nor is the VBA help file. I have to have it so that I can input a values for the x axis rotation and the y axis rotation so that my 3d surface graph will rotate whatever values I input, the 3d surface graph will rotate those degrees. I also have to have a method for having the default rotation. I was also wondering how to put scroll bars for the x and y rotation. The only other thing I am having trouble with is having an input to check box for right angle axes. So far I have two cells for entering the x rotation value and the y rotation value. I also already have my 3d surface graph.

I am currently trying to, using VB Express 2008, change some hyperlinks in a word document. The words which are associated to this hyperlinks also have bookmarks which I use to access them easily. The error I'm recieving says "Range is not a by reference property." [code] The error is produced by that last line. The full code is actually longer and it also runs through a process with Excel where it determines de variables used.

View 12 RepliesI have created some 3d models(VB) for display in a WPF 3d Viewport and would like to rotate them. I would like to rotate them about an axis of rotation defined by a line through two 3d points. All the examples seem to rotate about one of X Y or Z axes and are not helpful for a more general approach. The angle of rotation is easily found. My maths is a bit rusty now so is there a function that would calculate the axis easily ?

Good day, i have an application which can upload and preview image files, e-presentations, word duments, excel files and pdf files.

View 3 RepliesI'm developing a sun shading analysis tool, and part of the analysis involves rotating a house (modelled as a cube consisting of 8 points) by the solar azimuth and solar altitude angles. The reason for this is to determine if the wall in question is facing the sun, and if so I run a shading analysis using a scanline algorithm to determine the percentage of wall plane that is in shade from a tree in the yard (this is modeled using overlapping 2D polygons). The purpose of the rotation and tilt of the object is so that the wall plane is directly perpendicular to the sun, so that the analysis can be done in 2D as opposed to 3D.
I first rotate each point of the house (which is stored in an array) through the azimuth, and then tilt it up through the solar altitude angle. I have set up my 3D coordinate system using the standard right-hand rule for orientation of the x,y,z axes. I'm using a basic rotation matrix as follows:For the azimuth, I am rotating around the z-axis, so I am using the following matrix transformation.
[x',y'] = [x*cos(azimuth) - y*sin(azimuth) , x*sin(azimuth) + y cos(azimuth)]For the altitude, I am rotating the object about the x-axis to tilt it up. I use the initial z-coordinate and the transformed y'-coordinate for the altitude tilt calculation.Each point, when completely rotated and tilted, will have a distinct set of coordinates: [x', y'', z'].Individually, the rotation and tilt work fine. But when I try to do them consecutively, I run into problems.
I have a screen full of puzzle peices they are all rotated at different angles (90,180,270). is there a way to track the peices rotation? I was thinking of using a 2d array to store there rotation. however, I am using this code to rotate the peices:

i'm developing a simple 2d animation program. my task is to get the center point of a rotation, for example: at the frame 0 there is a rectangle at x,y coordinates and with 0° of rotation at the frame 10 there is the same rectangle, translated and rotated what is the center point around which the rotation occurred? This is not really a question about programming, i know, rather than a problem of geometry.

View 2 Repliesmy question is regarding working out the direction of the smallest angle between two vectors in 2D. I am making a game in C++ where one of the obstacles is a heat seeking missile launcher. I have it working by calculating the vector between the target and bullet, normalising the vector and then multiplying it by its speed. However, I am now coming back to this class to make it better. Instead of instantly locking onto the player I want it to only do so only when the bullets vector is within a certain angle (the angle between the bullets vector and the vector bulletloc->target). Otherwise I want it to slowly pan towards the target by a degrees thus giving the player enough space to avoid it. I have done all this (in a vb.net project so i could simplify the problem, work it out then re write in in C++). However the bullet always rotates clockwise towards the target even if the quickest route would be counter clockwise. So the problem is working out the direction to apply the rotation in so the smallest angle is covered. Here is my code so you can try and see what I am describing:
Function Rotate(ByVal a As Double, ByVal tp As Point, ByVal cp As Point, ByVal cv As Point)
'params a = angle, tp = target point, cp = current point, cv = current vector of bullet'
[Code]...
I had was to work out the bearing of the two vectors and if the difference is greater than 180 degrees, rotate clockwise otherwise rotate counter clockwise
SI like doing random things like 3D objects inside a windows form. With that said, I'm creating an application that will, eventually, write the code for me, after I do it myself visually.If you run the app it will make some more sense I guess.Now, to rotate the cubes, I'm using
.Transform.World = Matrix.RotationYawPitchRoll(CSng(CubeRx(1) / 10), CSng(-CubeRy(1) / 10), CSng(CubeRz(1) / 10))
now I do not want the world to rotate, just my individual cubes.Here's an example of me referring to my cube in action
If howmanycubes >= 1 Then

how to apply textures to the cube.instructions:When running the program, type in values on right side and click create cube.before you click create cube again, those same text boxes will adjust your current cube.Then when you click create new, it places another cube ontop of your current cube, so you'll need to give it new values.Not much validation is going on so some bad values will cause crashes.
What I need to do is query an iTextSharp AcroField to check if it is rotated, and if so capture the value of the rotation.So If I have the following field:

afi = af.GetFieldItem("fieldName")
What do I need to do to get the rotation (in degrees) of that specific field?
I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008.so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate.so far i've tried this:
Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle)
gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74)
gL.RotateTransform(angleLongNeedle)[code].....
As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control.

View 5 RepliesI am using API calls to transform a Bitmap object. I have various physical transformations (rotation, flipping, scaling, displacement) as well as some colour adjustments (inversion, brightness and contrast)Everything works fine except for when I use the rotation or shear transformations in combination with the colour adjustment. In that case the colours revert to the original image.The interesting thing about this problem is that it seems to be dependent on the off-diagonal factors (eM12 and eM21 below) in the XForm matrix. For example, here is the rotation matrix:
Public Sub RotateClockwise(Radians As Single)
With XFormMatrix
.eM11 = Cos(Radians)[code]....
is there some way I can use both SetWorldTransform and SetColorAdjustment when using non-zero values for the off-diagonal factors in my XForm transformation?
