Screen zoom effect quality loose

[esp]

Hello comunity !
Screen zoom effect is there any documentation ?
I'm using it and there are the result isn't rellay the best .

This is an image without screen zoom effect
cammera zoom.jpg

This is an image applying the screen zoom effect
cammera zoom2.jpg

The two images are the same size , the camera width and height are setted at the same dimentions of the frame , i don't understand why when the zoom effect is applyed there is tha blury effect .
Is there any way to avoid the blury effect / quality loose ??

this is odd,
I get exactly the same quality with or without scale applied at 1.0

maybe you can try to uncheck "antialiasing when resizing"
from application properties - window

without / with antialiasing at scale 2.0:

this should force crisp pixel scaling, if this is what you need?

Is it for iOS or HTML5?

I've tested above on HTML5

Hello schrodinger thank you for the answer , unfortunately I didn't found any "antialising" option (i'm not really good on using CF2.5 i'm still learning) . My game is for windows . Anyway I solved by using the viewport object !
