Pixel Counter - Count The Black Pixels The Grey Pixels The More Grey Pixels

Jul 27, 2009

I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white

This was my way and i don't think that is useful:

First of a button to convert the image to greyscale:

Dim bm as new Bitmap(source.Width,source.Height)

Dim x

Dim y

[CODE]...

Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb

The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.

Color Detection That Finds A Color At An Area?

Mar 9, 2012

I am using basic color detection that finds a color at an area. Then it uses basic if statement so "if something=something1 then" where something1 is the color. Anyway, I have all that fixed up right. The thing I want to do is tell the program check for the color for x amount of seconds.

Here is an example.

Dim something As Color = screenshot.GetPixel(50, 50)
Dim something1 As Color = Color.FromArgb(1, 1, 1, 1)
if something = something1

Black And Blue (color Testing)

Aug 4, 2010

Provided the following

vb.net Private Function isBlue(ByVal aRGB As Color) As Integer
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then

[CODE]....

I use it with the following:

vb.net Dim count As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
For x As Integer = 10 To 16

Works great. Takes a small square and tests for the blue color indicated by the aRGB value.

What I am trying to do now is test for all Black (as opposed to blue). I want to copy that isBlue Sub to a "isBlack" Sub and perform a like test, but I do not know what to use for this part:

If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then explain those values and what changes to each one does?

I've edited the code some:

vb.net Dim bluepixels As Integer = 0
Dim blackpixels As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)

[CODE]...

And in the sub I am testing for an R, G, and B value less than 3 (black should be all 0's) I'm still interested in how to manipulate those RGB values to test for other colors, or very specific hex colors.

Label .FixedSingle Border Is Not Really Color.Black?

Even with <label>.forecolor = Color.Black. I find that my labels' borders are not {255,0,0,0} but rather {255,100,100,100), a middlish gray, Is there some system setting (e.g., themes, Silverlight) from which the standard label draws its color?( I am familiar with the sub-classing work-around, but have hundereds of instances that would have to be changed.)

Array Of Integers - Blue And Black Color Lines

Feb 16, 2012

I have a form with a lot of LineShapes on it, and basically what I'm trying to do is make certain lines a blue colour and others a black colour, depending what it's in an array of integers. Each line is called line1, line2 etc. So if one of the values in the array is 3, then line3 would be coloured blue.

I have the following code to handle all the lines more easier:
MeterArray = New PowerPacks.LineShape() {line1, line2, line3, line4, line5}

However, since I'm going to have about 50 seperate lines, this is going to look quite messy when I reach line50. So my question is, is there a tidyier way of handling these lineshapes.

Changing A Fore Color To Black In A Rich TextBox?

Jan 3, 2012

So I have a Vertical Scroll which enables you to change the Foreground color of the highlighted text inside the Rich TextBox. Here is the code of the Vertical scroll named Vscrollbar1:

RichTextBox1.SelectionColor = Color.FromArgb(VScrollBar1.Value)

It does indeed work. Then I have a button that makes the Rich Textbox not Visible. Using Richtextbox1.visible=False Then I have an open button, which makes it Visible again. But what I wanted is that the text inside the Rich Textbox to be color Black; but the color of the from the scroll keeps appearing. Here is my code for the Close Button:

Richtextbox1.SelectionColor=Color.Black

I even changed it to this:

Vscrollbar1.Value=0

But still no difference.

Cursors (.cur) Only Render In Black And White - How To Make Them Color

Jun 5, 2009

I am using the cursor converter to set both

dim cCon as cursorconverter = new cursorconverter
me.cursor = cursorconverter.ConvertFrom(myCursor.cur)

and

windows.forms.cursor.current = cursorconverter.ConvertFrom(myCursor.cur)

the reason for setting both is that otherwise the cursor will not always have the desired appearance. I know that cursors can be rendered in color, like 3D-Bronze, windows animated, hands and variations.

ComboBox DropDown-Area Border Color?

Dec 6, 2010

I've created an ownerdraw ComboBox (used as DropDownList only) in Visual Basic .NET 2010. I inherited ComboBox and set DrawMode to OwnerDrawVariable. The control itself and the dropdown items are drawn with Paint and DrawItem.

The control works fine so far, but there is one thing i was unable to change: When i click on the combobox to open the dropdown area, this new area has a very bright border color (nearly white) which I want to change to black. I've uploaded an image of the current control and how I want it to look like:

Monitor An Area Of The Screen For A Certain Color In Visual Basic?

Apr 5, 2012

I'm designing a player application to accompany our phone system. As our calltakers take calls, it makes recordings of each call. They can go to a list module, find a recording and double click, which opens my player. The issue i have is that if the calltaker gets another call, my player doesn't know it and will continue playing. I'm looking for a way to monitor the screen in a particular area and when it sees yellow or red instead of blue, it will pause my player.

The phone system does not have any API's that I can hook onto, so I have to try it another way.

The screen resolution never changes and the queue buttons where they receive calls will always be static. When they get a call, a small area changes from the background color blue to yellow or red to indicate a call.

**EDIT Final Code based on answers below and question Memory Leak using GetPixel/GetDC in Visual Basic

Private Function CheckforCall()
Dim hDC As IntPtr = GetDC(0)

Load A GIF File, And Start With The First Pixel And Check To See If That Pixel Color Is Closer To Black, Red, Green Or Yellow?

Jan 30, 2009

I would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

Set The Viewable Area To A Smaller Screen Area?

Jun 11, 2012

Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.

Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000

[code]....

Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
