[SOLVED] Rotate View

Erenford — Tue, 01 Aug 2023 12:27:34 GMT

Hello everyone,

Is there a way to create a rotated navigator view thru API? I've tried setting the tranmat API_NavigatorView.tr but nothing happens after I do "APIEnv_NewNavigatorViewID".
2d tranmat of 45 deg. angle:

tmx[0] = 0.707107, tmx[1] = -0.707107, tmx[ 2] = 0.000000, tmx[ 3] = 0.000000
tmx[4] = 0.707107, tmx[5] =  0.707107, tmx[ 6] = 0.000000, tmx[ 7] = 0.000000
tmx[8] = 0.000000, tmx[9] =  0.000000, tmx[10] = 1.000000, tmx[11] = 0.000000

When I checked the values (APIEnv_GetNavigatorViewID) it changes it back to the default angle 0 tranmat

tmx[0] = 1.000000, tmx[1] = -0.000000, tmx[ 2] = 0.000000, tmx[ 3] = 0.000000
tmx[4] = 0.000000, tmx[5] =  1.000000, tmx[ 6] = 0.000000, tmx[ 7] = 0.000000
tmx[8] = 0.000000, tmx[9] =  0.000000, tmx[10] = 1.000000, tmx[11] = 0.000000

So the next thing I did is after creating the view I changed it back to the 45 angle (APIEnv_ChangeNavigatorViewID).

I checked the view again and it retained the tranmat, but when I clicked the view it is still not rotated.

What gives? The 45 angle tranmat above is ok I think since it is working in ACAPI_Database(APIDb_SetZoomID). (which by the way says [out] on the tranmat arg when its supposed to be [in])

Any ideas how to do this?
Thanks.

Hi Erenford,

Thanks for pointing out this issue.
Currently the transformation matrix in API_NavigatorView structure isn't modifiable through API.

I'll add this as feature request and hope we will fix this in the next hot fix.
After that you will be able to modify view's transformation with APIEnv_ChangeNavigatorViewID or in APIEnv_NewNavigatorViewID.

Regards,
Tibor

Ok noted.

Thanks.

Hello,

Any news on this? Has this been fixed in AC 18?
