If you set up a logo with video set to one size, then resize video, the logo is scaled correspondingly. For example, if the logo is originally set up for 320x240 video, and you change to 640x480 video, the logo will now display at twice the size of the original bitmap.
If you edit the logo settings while the logo is scaled up or down,, you will see an additional option, Rescale. It will be the second page in the sequence, after Enable.
If you click the Rescale button on this page, the logo will be resized to the same size as the original source bitmap.
If you do not click the Rescale button, you can edit the logo settings using the scaled logo. Even if you change to another bitmap image, the old scaling will be maintained.
The driver can display color logos on YUV video 4:2:2 packed, YUV12 planar, and YVU9 planar. The appearance may not be quite the same as the RGB version, however.
Detail of colored features may not be as crisp, because in the YUV modes color is not sampled at full pixel resolution.

DibDraw Overlay video is always RGB even when you have selected a YUV color format in the dialog. Preview video is always in the exact YUV or RGB format you have selected. Therefore, when using a YUV mode be sure to check the appearance of the logo in Preview mode before putting it to use. |
When Grey8 video format is selected, all logos including color logos are displayed in greyscale.
