How to copy and pastle image

Post by walter » Wed Mar 19, 2008 4:35 pm

I am GdPicturePro4 and I am trying to develop a process that cut an image
And paste on another image, and that this image has sandwiched possibility of moving
With the mouse, with the possibility of putting in to fix the image anywhere on
Image superimposed.

What is the function that use of gdpicturepro4 to copy and paste?

What is the function that I use to move the pasted image with the mouse?

Thankful now,

Hi,

There are several ways to perform this operation.

The sample I give below uses GetPixelArray1D() & SetPixelArray() methods.
It loads input1.jpg image, copies the rectangle of coordinate (0, 0, 100, 100) into arPixels() buffer then pastles the area to input2.jpg image :

Code: Select all

Dim arPixels() As Long

Imaging1.CreateImageFromFile ("input1.jpg")
Call Imaging1.GetPixelArray1D(arPixels, 0, 0, 100, 100)
Imaging1.CloseNativeImage
Imaging1.CreateImageFromFile ("input2.jpg")
Call Imaging1.SetPixelArray(arPixels, 0, 0, 100, 100)
Call Imaging1.SaveAsJPEG("output.jpg")
Imaging1.CloseNativeImage

Erase arPixels

Best regards,
