Creating huge high-resolution Bitmap bigger than 2

问题:

I want to create a huge resolution Bitmap-image so that to load it into memory and transform it based on user-gestures.

I noticed that the limit for new Bitmap(int32,int32); is around 23000 but I need like 1159480 x 45920 with a bitdepth of 32.

Can someone help me out or is this impossible to do? I have 8 gigs of RAM.

回答1:

ARE YOU REALLY SURE YOU NEED SUCH SIZE? It should be bigger than than 150GB. Moreover if you consider a point size of 1/72 of inch your image will be 409 km 500 m...

EDITED If you need a high resolution image of a large area you should consider to use multiple images with different resolutions (think Google Maps for example).

Have you looked at the Deep Zoom functionality in Silverlight?
