- Magnify Sample
-
- DESCRIPTION:
- The Magnify Sample illustrates creating
- IGBitmaps given a desktop rectangle. You
- specify the rectangle centered around the
- current mouse pointer. Based on a timer,
- the rectangle around the mouse pointer is
- passed to an IGBitmap constructor. A
- bitmap is then displayed in the client area.
- When the client area of the sample
- application is larger than the capturing
- rectangle, it has the affect of magnifying
- the desktop image.
-
- CONCEPT/FEATURE:
- Sample program for demonstrating
- IGBitmap, IGraphicContext, IGraphicBundle,
- IBitmapControl, INumericSpinButton, and
- ITimer.
-
- HOW TO BUILD THE PROJECT FROM THE COMMAND LINE:
- From within the directory containing the sample, simply type:
- NMAKE
-
- HOW TO BUILD THE PROJECT FROM WITHIN THE WORKFRAME ENVIRONMENT:
- Refer to the standard Workframe BUILD instructions
-
- HOW TO RUN THE PROJECT FROM THE COMMAND LINE:
- From within the directory containing the sample, simply type
- the name of the executable:
- MAGNIFY
-
- HOW TO RUN THE PROJECT FROM WITHIN THE WORKFRAME ENVIRONMENT:
- Refer to the standard Workframe RUN instructions
-
- SPECIAL NOTES:
- If the sample fails to execute or
- abnormally ends, you can get
- more information about the failure
- by turning on the ICLUI trace.
- This is done by setting the
- environment variable ICLUI_TRACE
- as follows:
-
- set ICLUI_TRACE=ON
- set ICLUI_TRACETO=STDERR
-
- ICLUI_TRACETO controls where
- the trace information is reported.
- With tracing turned on, ICLUI
- exception text will be written to a
- standard error file. For example:
-
- sample >sample.out 2>&1
-
- The exception data is now in the file
- 'sample.out'.
-
- ADDITIONAL HARDWARE/SOFTWARE REQUIREMENTS:
- None
-
