View Full Version : All overlays not showing

December 16, 2005, 12:49:43
I have a app that puts overlays on a live video display.

All works well with the color format on UYVY.

When change this to Y800 some of the overlays don't show.

The live video is in greyscale and I what to save the the images in greyscale to save disc space.

Maybe I sould do it differently.

Hello Bestbier,

could you show me, how you setup the Overlaybitmaps and the the video formats? With this i can reproduce you problem and find a solution.

I fixed it by changing the .memorycurrentcolorformat to ICY800.

Now I have the following lines of code:

.device = "DFG/SV1"
.inpurchannel = "01 Video: Composite"
.videonorm = "PAL_B"
.videoformat = "UYVY (768x576)"
imemorycurrentcolorformat = ICY800
.overlaybitmap.colormode = OVERLAY_COLORMODE_GRAYSCALE
.overlaybitmap.fonttransparent = False

and so on.

Hope that is right - well it seems to work.

Hi Bestbier,

this looks fine to me.
