Resizing an image physically changes its width and height, and changes the number of bytes required to store the image. This is different from zooming, which mathematically changes the displayed size of the image, without affecting the stored data.
When resizing an image to enlarge it, LEADTOOLS must find enough room to hold the resulting image. If necessary, LEADTOOLS uses virtual memory (disk space treated as memory). On a 32-bit system, it uses the system's virtual memory.
On a 16-bit system, it looks for memory as follows:
First it checks the Windows system resources (including 386 Enhanced virtual memory).
If the Windows system resources are insufficient, it checks the available space on the disk specified for temporary files (defined using the TEMP or TMP environment variable).
If there is not enough memory or virtual memory to hold the resulting image, the method returns an error code.
