Hello,
I recently purchased an i.MX6q Sabre-SD board and have been experimenting with the OpenVG API. I've installed the software found here: i.MX 6 Series Software and Development Tool Resources Product Summary Page and am using the oneirc rootfs image.
I installed the gpu-viv-bin-mx6q_3.0.35-4.1.0_armel.deb package (had to remove a conflicting package to do this) and have built/run the OpenVG samples in gpu_sdk_v1.00.tar.gz.
One thing that I've observed is that the maximum width and height of an OpenVG image is 1280x1280. When I call vgCreateImage with dimensions greater (say 1920x1080), it returns a VG_INVALID_HANDLE value (as expected). My question is whether or not the maximum VG Image dimensions can be adjusted to match the egl surface dimensions of 1920x1080?
I modified the OpenVg/Example1/Example1.c code to have an additional function:
static int check_bounds() {
EGLint qwidth = 0;
EGLint qheight = 0;
eglQuerySurface(egldisplay, eglsurface, EGL_WIDTH, &qwidth);
eglQuerySurface(egldisplay, eglsurface, EGL_HEIGHT, &qheight);
printf("[info]: egl width: %d, egl height: %d\n", qwidth, qheight);
VGint imageMaxWidth = vgGeti(VG_MAX_IMAGE_WIDTH);
VGint imageMaxHeight = vgGeti(VG_MAX_IMAGE_HEIGHT);
printf("[info]: imageMaxWidth: %d, imageMaxHeight: %d\n", imageMaxWidth, imageMaxHeight);
return 0;
}
And the output is:
[info]: egl width: 1920, egl height: 1080
[info]: imageMaxWidth: 1280, imageMaxHeight: 1280
Any thoughts or advice is much appreciated. Thanks!
