How to make a color curve adjasment for editing colors of an image?I found a C# project on Mr.SkyDrive but the problem is the coloring adjasment, because the coloring adjasment wasn't as other programs adjasment it wasn't correct if you view the image closely you will see some red, pink, and green pixels: (the curve like this must make the image negative)
View 20 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?

View 1 RepliesI'll try to clarify by using the following example. In here I have two Drop down lists (ddlInsertEmployee + ddlInsertCustomer) which should both be bound to fetch data from tables [Employee.EmployeeID] and [Customer.CustomerID] and insert it into table [Task].
The problem is that it inserts data from Employee.Fullname and Customer.Fullname into resp.Employee.EmployeeID and Customer. CustomerID.If I would change the Drop down lists to textboxes, and manually insert the IDs, it works like a charm, but this is not very efficient, I want to be able to see the entire Fullname.how to change my Sqlstring in order to make this work correctly.

View 2 RepliesI have a large set of latitude and longitude coordinates from a GPS which, when plotted, creates a 'jerky' line over time. I would like to 'smooth' this line into another set of coordinates which I can then plot to make the track more 'smooth'.
I may need to add more intermediate coordinates to do this. I just wondered if there are any code snippets out there or even MS Excel functions

View 4 RepliesI'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.
I am looking for a way to be able to export a beizer-curve (a curve like in the example below)from my app to a DXF-file.What I need is a way to calculate the control-points and parameters that DXF-format requires (format as in link below)
View 11 RepliesWrite a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
View 1 RepliesHow hard would it be to graph a curve of a function in a VB form.
Attached is a graph from excel which is exactly what I need to do.
I have the function of some fluid properties and I'd like to choose a min and max temp then have the function graphed, with temp as the x and the fluid property as the y which would auto scale to fit the curve.
Actually now the program i have to return the properties at one temp is just a GUI front end to call a fortran program to return the properties so actually if I just use that it'd be graphing points and not directly from the function. I can always make it completely VB based if graphing from a function is easier than points. It'd be a slight pain to rewrite all the code for the functions though.

View 14 RepliesThe picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.
My problem is centering the 0,0 points of my graph to the center of my picturebox
Dim picBoxWidth As Integer = picGraf.Size.Width
Dim picBoxHeight As Integer = picGraf.Size.Height
Dim halfWidth As Integer = picGraf.Size.Width / 2
[code]....
So how to I tell it to start at the center of my picturebox names (picgraf) btw.
I have searched and searched and searched. Nothing is working. Well it kind of works...I have a rtb which reads from a bunch (like 4.6k) xml files. Depending on the value of a few tags it displays a certain character. I want those characters to be color coded.
