Creating a Dib by only specifying the size with GDI+ and DotNet...
- by Kris Erickson
I have just recently discovered the difference between different constructors in GDI+. Going:
var bmp = new Bitmap(width, height, pixelFormat);
creates a DDB (Device Dependent Bitmap) whereas:
var bmp = new Bitmap(someFile);
creates a DIB (Device Independent Bitmap). This is really not usually important, except when handling very large images (where a DDB will run out of memory, and run out of memory at different sizes depending on the machine and its video memory). I need to create a DIB rather than DDB, but specify the height, width and pixelformat. Does anyone know how to do this in DotNet. Also is there a guide to what type of Bitmap (DIB or DDB) is being created by which Bitmap constructor?
