TPixmap

The Pixmap type

Example

SuperStrict

'Prompt the user for an image file
Local path:String = RequestFile("Select an Image File","Image Files:png,jpg,bmp")

Local pix:TPixmap

'Load the file into a TPixmap according to its format
Select ExtractExt(path)
    Case "png"
        pix = LoadPixmapPNG(path)
    Case "jpg"
        pix = LoadPixmapJPeg(path)
    Default
        pix = LoadPixmap(path)
EndSelect

'Ensure the file loaded
If Not pix Then
    Notify "The File Could Not Load. The Program Will Now End."
    End
End If

'Setup the window
Graphics 600,600,0,60,2
Repeat
    Cls
    DrawPixmap Image , 20 , 20
    Flip
Until KeyDown(KEY_ESCAPE) Or AppTerminate()

Fields

Returns

A new TPixmap object.


Method Paste( source:TPixmap,x,y )

Paste a pixmap


Method Convert:TPixmap( format )

Convert a pixmap

Returns

A new TPixmap object in the specified format


Method ReadPixel( x,y )

Returns

The pixel at the specified coordinates packed into an integer


Method WritePixel( x,y,argb )

Write a pixel to a pixmap


Method WritePixel(x:Int, y:Int, col:SColor8)

Writes a pixel to a pixmap of the specified SColor8


Method ClearPixels( argb )

Clear a pixmap

Example

SuperStrict

Graphics 800 , 600

Local mypix:TPixmap = LoadPixmap(BlitzMaxPath()+"/samples/hitoro/gfx/boing.png")
If mypix = Null Then
    RuntimeError ("Error Loading Image")
End If

DrawPixmap mypix, 0, 0
