GDI+Desktop graphics and printing library

[berndgoedecke]

Hello AGraham,
I use GDI Desktop to save a Bitmap to a File like this:
BMapExCop.SaveImage(AppPath & "\Temp\Blob.jpg")
It works in the Editor even if the GDI Desktop Help references another syntax like this:
BMapExCop.SaveImage(PathName As String, Channel As String, Format As String)
During compilation I get the cs1525 error.
What is wrong?

Best regards

There's nothing wrong. The method call should have a format parameter. The IDE isn't strict enough in its' checking, it really should give you an error. You don't get an error from the library because it defaults to JPG if it doesn't understand the format string, or lack of, given to it.

Hello AGraham,
i've tried some kind of Syntax in the BitBlit-command:

BMapExCopM.Value = BMapExCopM.BitBlt(BMapExCop.Value, StrRec.Value, 0, 0, D=D<S )

or

BMapExCopM.Value = BMapExCop.BitBlt(BMapExCop.Value, StrRec.Value, 0, 0, D=D<S )

or

SRCCOPY = 13369376 '(&HCC0020)
BMapExCopM.Value = BMapExCopM.BitBlt(BMapExCop.Value, StrRec.Value, 0, 0, SRCCOPY)

or

SRCCOPY = 13369376 '(&HCC0020)
BMapExCopM.Value = BMapExCop.BitBlt(BMapExCop.Value, StrRec.Value, 0, 0, SRCCOPY)

but always appears the error "Raster op is not valid".
How this function operates?

Best regards

From the help

BitBlit(src As Image, srcrect As Rectangle, destleft As Int32, desttop As Int32, rasterop As String )

Also there is no return value from BitBlit

"The existing internal bitmap is modified."

try

BMapExCopM.BitBlt(BMapExCop.Value, StrRec.Value, 0, 0, "D=D<S")
