maybe like that:

Code: Select all

UsePNGImageEncoder() 

LoadPic=0 ;<----
EndPic=1;<----

	Procedure RedFilter(x, y, QuellFarbe, ZielFarbe) 
		ProcedureReturn RGBA(Red(QuellFarbe), Red(ZielFarbe), Red(ZielFarbe), Alpha(ZielFarbe)) ;<----
	EndProcedure 
	 
	Directory$ = GetCurrentDirectory() ; Listet alle Dateien und Ordner im 'Home'-Verzeichnis auf 
	If ExamineDirectory(0, Directory$, "*.bmp")   
		While NextDirectoryEntry(0) 
			If DirectoryEntryType(0) = #PB_DirectoryEntry_File 
				Type$ = "[File] " 
				Size$ = " (Size: " + DirectoryEntrySize(0) + ")" 
				If LoadImage(LoadPic, DirectoryEntryName(0)) 
					IMX=ImageWidth(LoadPic) 
					IMY=ImageHeight(LoadPic)  
					IMD=ImageDepth(LoadPic) 
					
					If CreateImage(EndPic,IMX,IMY,IMD) 
					  StartDrawing(ImageOutput(EndPic)) 
					  DrawImage(ImageID(LoadPic), 0, 0)
						DrawingMode(#PB_2DDrawing_CustomFilter ) 
						CustomFilterCallback(@RedFilter()) 
						Box(0, 0, IMX, IMY,RGBA(255,0,0,255))
 
						StopDrawing() 
					EndIf  
; 					SaveImage(EndPic, DirectoryEntryName(0)+"Red.bmp") 
					SaveImage(EndPic, DirectoryEntryName(0)+"Red.png",#PB_ImagePlugin_PNG) 
					FreeImage(EndPic) 
					;FreeImage(EndPic) 
					RunProgram(DirectoryEntryName(0)+"Red.png")
				EndIf 
			Else 
				Type$ = "[Directory] " 
				Size$ = "" ; A directory doesn't have a size 
			EndIf 
			 
; 			Debug Type$ + DirectoryEntryName(0) + Size$ 
		Wend 
		FinishDirectory(0) 
	EndIf

Use constants ...

Code: Select all

Enumeration ; Pictures
  #LoadPic
  #EndPic
EndEnumeration
