Why resize images for DPI ROC

3

But you’ve seen the same ‘full image’ on a camera 3” LCD, a 15” laptop and maybe a 22” desktop.

This is only possible if the different processors “resample” the image and give you a “Preview” or approximation of the image.

The results are pretty accurate but there can be noticeable differences.


Processor A

Processor B

Processor C

All digital images for ROC must fall within maximum pixel sizes

• The maximum width of an image is 1400 pixels

• The maximum height of an image is 1050 pixels

This is because our projector’s maximum resolution is

1400 (w) x 1050 (h) pixels.

Entering this sized image means that the processor in the projector will not affect your image.

It will not resample it so the image will remain just as you edited it.


5 Why rename images for DPI ROC Images must be named in a special format to work with the software.

This is the only way the competition software can produce reports for judges that remove the membership numbers.

Number with a 0 in front

e.g. 01 02

An ‘underscore’

A title separated by only spaces no dashes etc.

An ‘underscore’

Your membership number

All images must be named in this format:

e.g. 01_The White Knight_229N 02_The best of friends_229N

It’s important to use an ‘underscore’ not a dash. To get the underscore use [SHIFT] +
