Tool/software:
Hello,
I'm developing a kind of device by porting the linux kernel(3.12.10) to the AM437X.
And, I'm using Qt application for displaying camera image.
FILE *f;
/* Set manager for alphablending */
f = fopen("/sys/devices/platform/omapdss/manager0/alpha_blending_enabled", "w");
fprintf(f,"%d",1);
fclose(f);
f = fopen("/sys/devices/platform/omapdss/manager0/trans_key_enabled", "w");
fprintf(f,"%d",1);
fclose(f);
like this code.
At this, I want to display an image with transparency.
The UI is overlaid with transparent images(transparency: 60%), but the camera is not.
How can I solve this problem?
