ScreenShot of a specified area

[weissenb]

Hello!
I want to make a batch making screen shots from a specified area and save the pictures with specified names.
This script only takes a whole screen:

Some years ago I had a script for that but i cannot find that.

Perhaps someone has a solution.

Thank you very much

Hi,
in the Tech Database, do a search for "Article ID:   W15998" and that should find the routine you used to have and were looking for.

It could be updated to use the newer DllStruct* functions but here is  link the article mentioned by IFIcanByte

My sense is that the essence  of this thread is that there are two possible general approaches to the problem of getting a "ScreenShot of a specified area":

1) You could take a screenshot of the whole screen, then use functions in the Pixie Extender to crop the result down to the area that you are interested in.

or

2) You could use some magic to only get the area you are interested in (before doing the snapshot).

I have used method 1 in my work.  I don't know if method 2 exists or is possible.  Is it?

The Pixie extender is deprecated because it is buggy and because you can access the same functionality by using ImageMagic as a COM server. The Tech Database has an example

If I remember correctly, the article first mentioned by  IFICantBYTE shows how to grab a specific area of the desktop and convert it to a bmp file using GDI functions via DllCall.
