How to Overcome the 'Parameter is Not Valid' Error When Creating Large Bitmaps in .NET?

Creating a Bitmap Larger Than 19,000px: Resolving "Parameter is Not Valid" Error

When attempting to create a bitmap with dimensions exceeding 19,000 pixels using the System.Drawing.Bitmap constructor, you may encounter the following error: "Parameter is not valid." This error stems from the excessive memory allocation required for such a large bitmap.

Workaround:

Unfortunately, there is no straightforward workaround to create bitmaps larger than 19,000px using the System.Drawing.Bitmap class. This limitation is rooted in the amount of contiguous memory required for these extensive bitmaps.

As mentioned in the referenced MSDN forum thread (http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/37684999-62c7-4c41-8167-745a2b486583/), .NET restricts the creation of images that consume excessive memory.

For reference, the memory consumption formula for an image is as follows:

bit-depth * width * height / 8

For an image with dimensions of 40800 pixels by 4050 pixels, this equates to over 660 megabytes of memory.
