dmICGetNum, dmICGetDescription - find out about available image converters
As shipped in IRIX 6.5.22. Unchanged since IRIX 6.5.
NAME dmICGetNum, dmICGetDescription - find out about available image converters SYNOPSIS #include <dmedia/dm_imageconvert.h> int dmICGetNum(void); DMstatus dmICGetDescription(int i, DMparams *converterParams); DESCRIPTION dmICGetNum returns the number of image converters available.This value may change from invocations to invocations, depending upon whether any image converters has been added or removed from the system since its last invocation. dmICGetDescription returns the description of the indicated converter. The value of the i argument ranges from 0 to one less than the value returned by dmICGetNum. The description consists of the values of the following DMparams parameters: DM_IC_ID Use dmParamsGetInt to return 4 character value of this parameter. This 4 character code is a unique to an algorithm in the system. For example, all converters that uses the jpeg algorithm has the 4 character code DM_IC_ID DM_IC_ENGINE Use dmParamsGetString to return the character string value of this parameter. This string is an english description that describes the engine name used for this particular conversion algorithm. DM_IC_SPEED Use dmParamsGetEnum to return one of the following values of this parameter: DM_IC_SPEED_REALTIME suitable for real time performance DM_IC_SPEED_NONREALTIME not suitable for real time performance DM_IC_SPEED_UNDEFINED speed undefined DM_IC_CODE_DIRECTION Use dmParamsGetEnum to return one of the following values of this parameter: DM_IC_CODE_DIRECTION_ENCODE encode converter DM_IC_CODE_DIRECTION_DECODE decode converter DM_IC_CODE_DIRECTION_UNDEFINEDcode direction undefined DM_IC_VERSION Use dmParamsGetInt to return the version of the image converter. DM_IC_REVISION Use dmParamsGetInt to return the revision of the image converter. SEE ALSO dmICChooseConverter(3dm), dmICCreate(3dm), dmParams(3dm).
