key osSetDynamicTextureDataBlendFace(string dynamicID, string contentType, string data, string extraParams, integer blend, integer disp, integer timer, integer alpha, integer face)
Renders a dynamically created texture on the face of a prim containing the script, possibly blending it with the texture that is already set for the face. Returns UUID of the generated texture.

Example(s) 
// Example of osSetDynamicTextureDataBlendFace used to put a number on each face of a prim
 
string FontName = "Arial";
integer FontSize = 128;
 
NumberEachFace() {
    integer face = llGetNumberOfSides();
    while (face--) {
        string text = (string)face;

        commandList = osSetFontName(commandList, FontName);
        commandList = osSetFontSize(commandList, FontSize);
        commandList = osDrawText(commandList, text);
        osSetDynamicTextureDataBlendFace("", "vector", commandList, "width:256,height:256", FALSE, 2, 0, 255, face);
    }
}

    }
    changed(integer change) {
        if (change & CHANGED_SHAPE)
            NumberEachFace();
    }
}

With transparency: 

// Example of osSetDynamicTextureDataBlendFace used to put a number on each face of a prim with transparency
 
string FontName = "Arial";
integer FontSize = 128;
 
NumberEachFace()
{
    integer face = llGetNumberOfSides();
 
    while (face--)
    {
        string text = (string)face;
        vector size = osGetDrawStringSize("vector", text, FontName, FontSize);
        integer xpos = (256 - (integer)size.x) >> 1;
        integer ypos = (256 - (integer)size.y) >> 1;
 
        string commandList = "";
        commandList = osMovePen(commandList, xpos, ypos);
        commandList = osSetFontName(commandList, FontName);
        commandList = osSetFontSize(commandList, FontSize);
        commandList = osDrawText(commandList, text);
        osSetDynamicTextureDataBlendFace("", "vector", commandList, "width:256,height:256,Alpha:0", FALSE, 2, 0, 255, face);
    }
}
 
default {
    state_entry() {
        NumberEachFace();
    }
    changed(integer change) {
        if (change & CHANGED_SHAPE)
            NumberEachFace();
    }
}

With blending:

string FontName = "Arial";
integer FontSize = 128;
 
NumberEachFace()
{
    integer face = llGetNumberOfSides();
 
    while (face--)
    {
        llSetTexture(TEXTURE_PLYWOOD, face);
        string text = (string)face;
        vector size = osGetDrawStringSize("vector", text, FontName, FontSize);
        integer xpos = (256 - (integer)size.x) >> 1;
        integer ypos = (256 - (integer)size.y) >> 1;
 
        string commandList = "";
        commandList = osMovePen(commandList, xpos, ypos);
        commandList = osSetFontName(commandList, FontName);
        commandList = osSetFontSize(commandList, FontSize);
        commandList = osDrawText(commandList, text);
        osSetDynamicTextureDataBlendFace("", "vector", commandList, "width:256,height:256,Alpha:0", TRUE, 2, 0, 128, face);
    }
}
 
default {
    state_entry() {
        NumberEachFace();
    }
    changed(integer change) {
        if (change & CHANGED_SHAPE)
            NumberEachFace();
    }
}



Parameters
Name Description Remarks
dynamicID UUID of already existing dynamic texture. Intended to accept UUID from a previous call to osSetDynamicTextureXXXX functions in order to provide modification of an existing dynasmic texture NOT IMPLEMENTED YET
contentType specifies the type of the data parameter.

The following values are allowed:

  • vector - the data parameter contains a list of drawing instructions. See Drawing commands for details
data Contains a series of drawing instructions. See Drawing commands for details
extraParams additional optional parameters in the following format: [param]:[value],[param]:[value]

Multiple parameters are separated by commas. The following ones are supported:

  • width - width of the dynamic texture in pixels (example: width:256)
  • height - height of the dynamic texture in pixels (example: height:256)
  • alpha - alpha (transparency) component of the dynamic texture. Values are from 0-clear to 255-solid.(example: alpha:255)
  • bgcolour - specifies the background color of the texture (example: bgcolour:Red)
  • altdatadelim - specifies a delimiter between the draw commands contained in the data parameter.
  • setalpha - integer value is treated like specifing aplha component
  • lossless - true or false, default false
blend If true, the newly generated texture is blended with the appropriate existing ones on the prim.
disp Display flags. Value 1-expire deletes the old texture if it is replaced by a newer generated texture (may not currently be implemented). Value 2-temp flags the asset as temporary, which often means that it is not persisted to the database.
timer specify a time interval to update the texture NOT IMPLEMENTED YET
alpha The alpha value of the generated texture. 0 (full transparent) to 255 (solid)
face The face of the prim on which to put the generated texture. If ALL_SIDES then all sides of the prim are set.

Notes

The dynamicID parameter is not implemented. The value passed will be ignored.

The timer parameter is not implemented. The value passed will be ignored. Instead, you can use a timer event and recall the function to get the same effect.

lossless parameter added on version 0.9.1.1, Nov 4th 2019. Old versions did as true, but that should one be used if needed
