CROPPING WHILE ROTATION

Karthik Ram

Hello,

I need a clarification about image rotation. If my image size is 1024 x 768 and my lcd resolution is 1280 x 768, what will happen if I rotate the image.

1. Will the image re-size it automatically and fit itself in the lcd screen?

2. If the engine does not re-size the image before rotation, will the image be cropped?

3. Else it is the duty of the developer to use re-sampling engine to down sample the image?

With regards,

Karthik.

Karthik,

It is entirely the application's responsibility to do whatever it needs to do when a rotated image has different resolutions to the target display.

This is because there are many different possibilities and it is up to the developer to decide how they want the application to behave.

Cropping and re-sizing are both options. Additionally you could scale whilst keeping the aspect ratio, or you could scale to fit etc... It depends on your application requirements.

BR,

Steve

hi Steve,

i want to implement CROP feature in our IP Camera.

i want to know what needs to be done like how to enable CROP and what resolutions we can crop, how many crop's we can do per frame.

i am not finding any document or details about crop.
