Dobrý den, jsem začátečník ve visual basicu a mám takovýto kód, vím že je to paskvil ale to ted prosím neřešte, potřebuji poradit jak udělat v třetím řádku od spodu následující (něco na tenhle způsob, s touhle funkcí):
If True And Form2.Button2.BackColor = Color.Red Then New Bitmap(zkouska1)BackColor = Color.Red
Chápete? aby Když vyvolám ten "klik" který je řešený posledním odstavcem v kódu a ten button2 na Forme2 bude zároveň červený, potrebuju aby se tedy ta vykreslena bitmapa (zkouska1) prebarvila do cervene barvy...
Public Class zkouska1
Private _zkouska1 As New Bitmap("C:\Users\w\Desktop\brno_skola\reduta\Program\Bila\1.png")
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
Form1.Show()
Form2.Show()
MyBase.OnPaint(e)
e.Graphics.DrawImageUnscaled(New Bitmap(_zkouska1), 0, 0)
End Sub
Private Sub zkouska1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
MyNewSub()
End Sub
Sub MyNewSub()
BackColor = Color.Red
TransparencyKey = BackColor
End Sub
Private Sub Example_ControlAdded(ByVal sender As Object, ByVal e As System.Windows.Forms.ControlEventArgs) Handles Me.ControlAdded
AddHandler e.Control.MouseClick, AddressOf Example_MouseClick
End Sub
Private Sub Example_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick
If True And Form2.Button2.BackColor = Color.Red Then ??? řešení ???
End Sub
End Class
Pomohlo by neco z tohohle?:
To set a single color for a bitmap you can use:
Public Function GetColoredBitmap(w as Integer,
h as Integer,
col as Color) as Bitmap
Dim bmp as New Bitmap(w, h, PixelFormat32bppPARGB)
Using g as Graphics = Graphics.FromImage(bmp)
g.Clear(col)
End Using
Return bmp
End function
Incorporate as needed. One way is to do this:
Private sub Button2_Clicked(s as object, e as eventargs) handles Button2.Click
Dim bmp as bitmap = GetColoredBitmap(100, 100, Button2.BackColor)
bmp.SaveAs("path/to/file.png")
bmp.Dispose
End sub
Update:
To alter an existing bitmap, modify to:
Public Sub ColorBitmap(bmp as Bitmap, col as Color)
Using g as Graphics = Graphics.FromImage(bmp)
g.Clear(col)
End Using
End Sub
