Hi,
I did check the image types obtaines with QCAR::Image and I see the following :
First one : GRAYSCALE
Second one : YUV
Thirs one: GRAYSCALE
Last one : GRAYSCALE
I believe that the image that I need is the second one, the YUV one.
I develop on Xcode for Iphone, doest the Java trick will word ?
Because the image type is YUV, does the trick still the same or I need to use another one ?
thanks
Regis

Hi regisima,
You do not need to use YUV format.
Probably the easiest way is to use code something like I have posted below.

RGB565 and RGB888 on iOS have a significant performance penalty (>20% CPU hit), because it isn't a native format for an iOS device. iOS has two choices YUV (the native format) and BGRA. So...

Hi,
I have an error for thoses lines below for the symbol ->
The error is the following :
QCAR::Image convert from YUV to PNG or JPG
The error happens because XCode cannot find the definitions for the class.
So, you need to add this line at the top:
#import <QCAR/Image.h>

Hi,
It works !
But I have to stay a bit longer on the model that I'm taking the picture on to get it well.
Can you tell me on how to reduce the image quality to medium or to low.
