Utilizando PNG
por Ian Sex 18 Fev 2011, 07:48
Primeira crie uma from ou utilize qual quer uma do pro prio eclipse origins depois adicione uma picture box
e um buton depois dissu de um duplo click na from e adicione o siguinte
- Spoiler:
- Código:
Option Explicit
Private WithEvents graphics As cGraphics
Private WithEvents bitmap As cBitmap
Public Obj As Object
Private Sub Command1_Click()
LoadPicture 'esse comando sera uzado para carregar IMG ele pode ser uzado tam bem na from load para não necessitar de uzar algum button
End Sub
Private Sub LoadPicture()
Set Obj = Picture1
Set bitmap = New cBitmap
Set graphics = New cGraphics
bitmap.LoadFromFile App.Path & "\IMG.png" 'aki e o Nome da IMG que voce ira Uzar
graphics.CreateFromHDC Obj.hdc
graphics.DrawImageRectI bitmap.Handle, 0, 0, Pixel(Picture1.Width), Pixel(Picture1.Height)
graphics.Dispose
End Sub
Private Sub Form_Unload(Cancel As Integer)
'esse comandos são feitos para descarregar os modulos
Set graphics = Nothing
Set bitmap = Nothing
End Sub
Private Function Pixel(ByVal lVal As Long) As Long
Pixel = Me.ScaleX(lVal, vbTwips, vbPixels)
End Function
Private Function Twip(ByVal lVal As Long) As Long
Twip = Me.ScaleX(lVal, vbPixels, vbTwips)
End Function
depois adicione um modulo e coloque o nome dele de ModGrafico e adicione o siguinte nele
- Spoiler:
- Código:
Option Explicit
Private Declare Function BitBlt Lib "gdi32" _

Private Declare Function GetWindowDC Lib "user32" _

Private Declare Function ReleaseDC Lib "user32" _

Public Sub PrintScreen(ByVal Frm As Form, ByVal oObj As Object)
Dim hWndDesk As Long

Dim LeftDesk As Long
Dim TopDesk As Long
Dim WidthDesk As Long
Dim HeightDesk As Long
LeftDesk = Frm.Left + fLeft(Frm, oObj)
TopDesk = Frm.Top + fTop(Frm, oObj)
WidthDesk = oObj.Width
HeightDesk = oObj.Height
hWndDesk = GetDesktopWindow()
hDCDesk = GetWindowDC(hWndDesk)
BitBlt oObj.hdc, 0, 0, WidthDesk, HeightDesk, hDCDesk, LeftDesk, TopDesk, vbSrcCopy
ReleaseDC hWndDesk, hDCDesk
End Sub
Public Function fTop(ByVal Frm As Form, ByVal Ctl As Control) As Single

End Function
depois dissu a dicione dois class modulo coloque 1 com nome cBitmap outro com nome cGraphics
no modulo cBitmap coloque

pronto galera depois dissu tudo faça o siguinte baixe esse arquivo aki abaixo e coloque no seu projeto ou no seu windows sytem32 depois de colocar o arquivo na pasta faça o siguinte va hein Project>>References>>GDI+ tlb By wpsrj1@syix.com
- Spoiler:
- Foto de como vai ficar
pronto galera agora FIM não esqueção de dar os credes por Tio Ian ^^
Download da Library
Projeto + Soucer
Creditos:Ian por fazer o sistema eo tutorial
Willian DOido por Cria a Library GDI+ para esse tutorial
OBS: fiz esse tutorial para voces utilizarem nas suas Guis graficos melhores do que os arquivos velhos e pesados ou ate se consiguir utilizar sprites hein PNG

Aconcelho não utilizar isso fikdik/,mais se teu jogo usa muita imagem sem passar pelo DirectX, utilize com moderação (y).

Boa Ian, assim quem gosta de um pouco mais de "luxO" na GUI vai aproveitar.
Mas como o Zero falou... Eu não usaria png em um server que eu queira mais de 50 players on =D
Mas tem gente que quer, então +1 credito =D
