Thank you Dimitris

Yasou Dimitris,
As far as I can see after a first quick check, all works as advertised.
In my app InvertImage also works for JPEGs (24-bit depth). The last
version appeared to have had a problem with GIFs only, which I can
no longer confirm. As the saying goes in Australia, "You're a bloody legend!"
Congrats on a big job. You have just added a few free drinks to your
accommodation
Cheers
Robert

the command "DrawImage(targetImage, sourceImage, x, y, width, height) " refuse to work for me. You say that it returns the image but the target is also defined as an argument.
I'll appreciate an example.
I tried to use it as a way to go around the fact that copying an image to a form resize it so that it fit within the form, while I need it to keep its size.
Thanks
David

Hello Dimitris,
I tried also the DrawImage function and didn't get a result. I agree with derez that an example would be of interest.

For the moment I use CopyImage
Sub HScroll_ValueChanged
ErrorLabel(DoneH)
MapX=HScroll.Value
bmpMap.Value=MapImage.CopyImage(ImageList1.Item(Ma p_I),MapX,MapY,GW,GH)
' bmpMap.Value=MapImage.DrawImage(frmMain.Image,Imag eList1.Item(Map_I),MapX,MapY,GW,GH)
frmMain.DrawImage(bmpMap.Value,GX0,GY0)
DoneH:
End Sub

CopyImage is OK
DrawImage not

The ErrorLabel(DoneH) is to avoid an Out of memory error.

I use it in a small program to display parts of a bigger bitmap (in my case maps) onto a defined area on the screen.

Best regards

Help file for dzImage library attached.

Klaus, derez - see the definition of DrawImage in the help. The folowing works for me.

	ImageClass.New1
	bmp1.new1(AppPath & "\one.jpg")
	bmp2.new1(AppPath & "\two.jpg")
 	bmp1.Value=ImageClass.DrawImage(bmp1.value,bmp2.value,40,40,20,20)
	form1.DrawImage(bmp1.Value,0,0)

Hello agraham,

I'd like to thank you very very much!!!

I may have missed it, but is there an way to use this (or another library if someone else knows of one) for simple picture processing (brightness, contrast, Gamma being the obvious examples).

I only want it for eye candy, so I'm trying not to write the function myself, working one pixel at a time.

Thanks Agraham
This made it sink down: "Returns the new combined image leaving the originals unchanged."

Hello LineCutter,

As far as I know there is not such a library.
