| Set Blend Map Gain Values | |
|---|---|
| Write Parameter(s) | |
| Byte | Description |
| Byte 0 | Compressed Values Passed bit0: 1 = Compressed data is passed below for Gain values. 0 = Uncompressed data is passed below for Gain values. |
| Byte 1 | Color Channel Select 0 = Broadcast 1 = Green 2 = Red 3 = Blue |
| Bytes 2-3 | Here the total number of compressed values needs to be passed only when CompressionEnable is Enabled otherwise pass 0 here |
| Bytes 4-5 | Starting Index for filling the Gain values in array of Gain |
| Bytes 6 - * | Gain of control points .The format of input should be such that required gain which is a value between 0 to 1.99 be multiplied by 4096 before passing it in command. |
This command takes the user given gain values of control points as part of the Blend Map. Using this command user passes the Gain values for the 2016 (63x32) control points. The gain values needs to be specified for each of the color channel. There are two features here for using the command. User can select the broadcast values option from the Color Channel Select. What broadcast does is that user needs to pass values only once and it will broadcasted to all the three color channels R,G,B. Otherwise user needs to pass value for R, G, B color channels separately. So the command will then be required to use 3 times one time for each color channel Another feature supported is passing compressed values. The compression used is RLE2 compression. For passing compressed values user needs to enable the Compression Enabled bit |

| Get Blend Map Gain Values | |
|---|---|
| Read Parameter(s) | |
| Byte | Description |
| Byte 0 | Color Channel Select 0 = Broadcast 1 = Green 2 = Red 3 = Blue |
| Bytes 1-2 | Start index in the Blend map channel gain values from which the data is to be read |
| Bytes 3-4 | Number of entries to be read |
| Return Parameter(s) | |
| Byte | Description |
| Byte 0 | This tells whether the gain values obtained are compressed data or not. |
| Bytes 1 - * | Selected Color Channel gain values |
This command reads from the blend map table already loaded using Set Blend Map Gain Values command. N Blend map gain values (that does not exceed the command packet size) can be read at a time from anywhere within the table. |
|
| Set Apply Blend Map | |
|---|---|
| Write Parameter(s) | |
| Byte | Description |
| Byte 0 | Blend Map Upload bit0: 1 = Blend Map values is enabled and applied. 0 = Blend Map values is disabled. |
This command is used to apply the Blend map with the given configuration |
|
| Set Blend Map Offset Values | |
|---|---|
| Write Parameter(s) | |
| Byte | Description |
| Byte 0 | Compressed Values Passed bit0: 1 = Compressed data is passed below for Offset values. 0 = Uncompressed data is passed below for Offset values. |
| Byte 1 | Color Channel Select 0 = Broadcast 1 = Green 2 = Red 3 = Blue |
| Bytes 2-3 | Here the total number of compressed values needs to be passed only when the first parameter is 1 otherwise pass 0 here |
| Bytes 4-5 | Starting Index for filling the Offset values in array |
| Bytes 6 - * | Offset of control points.The format of input should be such that the offset values are in the internal floating point format of s1m8e4 . |
Using this command user passes the Offset values for the 2016 (63x32) control points. The Offset values needs to be specified for each of the color channel R,G,B. The range of offset values in the standard floating point format is -255 to +255. There are two features here for using the command. User can select the broadcast values option from the Color Channel Select. What broadcast does is that user needs to pass values only once and it will broadcasted to all the three color channels R,G,B. Otherwise user needs to pass value for R, G, B color channels separately. So the command will then be required to use 3 times one time for each color channel. Another feature supported is passing compressed values. The compression used is RLE2 compression. For passing compressed values user needs to enable the Compression Enabled bit |

| Byte | Description |
| Bytes 0-1 | Horizontal Overlap with other projectors (pixels) |

| Byte 5 | Storage Options 0 = Dont Store 1 = Write To Storage 2 = Write To Storage Apply At Startup |
| Bytes 6 - * | Geometric adjustment parameters. Dependent on adjustment type used |
This command sets overlap and geometry parameters for semi-manual edge blending, creates and applies blending and warping maps for given blending inputs. It is necessary to call commands to enable manual warping and enable edge blending separately, for the results to take effect. Geometry parameters are dependent on geometric adjustment type. For no geometric correction, no parameters are used. For correction by keystone corners, the 8 parameters are the (x,y) coordinates (zero based) of the keystone corners in raster scan order : top-left, top-right, bottom-left, bottom-right. |
