The RPF BitmapIO class provides a function published interface for RPF I/O that gives access to the settings of the image format to be saved.
As with all FP interfaces, you can access the interface properties directly without explicitly supplying the interface name, for example rpf.colorDepth is the same but shorter than rpf.iRPFio.colorDepth
Interface: rpf.iRPFio Properties:
.colorDepth : integer : Read|Write Get/Set the color depth in bits per channel. Possible values are 8, 16 and 32.
.alpha : boolean : Read|Write Enable/Disable the saving of alpha channel.
.premultAlpha : boolean : Read|Write Enable/Disable premultiplied alpha.
.description : string : Read|Write Get/Set the file description string.
.author : string : Read|Write Get/Set the author string.
.zChannel : boolean : Read|Write Get/Set Z-buffer channel saving.
.mtlIDChannel : boolean : Read|Write Enable/Disable material ID channel saving.
.nodeIDChannel : boolean : Read|Write Enable/Disable node ID channel saving.
.uvChannel : boolean : Read|Write Enable/Disable texture coordinates channel saving.
.normalChannel : boolean : Read|Write Enable/Disable normal vector channel saving.
.realpixChannel : boolean : Read|Write Enable/Disable non-clamped color channel saving.
.coverageChannel : boolean : Read|Write Enable/Disable coverage channel saving.
.nodeRenderIDChannel : boolean : Read|Write Enable/Disable node render ID channel saving.
.colorChannel: boolean : Read|Write Enable/Disable color channel saving.
.transpChannel : boolean : Read|Write Enable/Disable transparency channel saving.
.velocChannel : boolean : Read|Write Enable/Disable velocity channel saving.
.weightChannel : boolean : Read|Write Enable/Disable sub-pixel weight channel saving.
.maskChannel : boolean : Read|Write Enable/Disable sub-pixel mask channel saving.
EXAMPLE
x = rpf.colorDepth--color depth value of 8, 16, or 32 rpf.colorDepth = 32--set color depth to 8bpp rpf.description ="Final Rendering"--set the file description string rpf.author ="Da Masta of Pixelz"--set the author name string rpf.zChannel = true--enable Z-Buffer saving
