| OFString I2DImgSource::getImageFile | ( | ) | [inline] |
Returns the input image file that currently associated with plugin.
- Returns:
- The filename of the image input file
| virtual OFString I2DImgSource::inputFormat | ( | ) | const [pure virtual] |
Returns identifier for the image input format the plugin imports.
- Returns:
- A short identifier (e. g. "JPEG")
Implemented in I2DJpegSource, and I2DBmpSource.

Extracts the raw JPEG pixel data stream from a JPEG file and returns some image information about this pixel data.
Raw means here that all APP markers (e.g. JFIF information) are removed from the JPEG stream. The pixel data returned is a JPEG stream in JPEG interchange format. This function allocates memory for the pixel data returned to the user. The caller of this function is responsible for deleting the memory buffer
- Parameters:
-
rows - [out] Rows of image cols - [out] Columns of image samplesPerPixel - [out] Number of components per pixel photoMetrInt - [out] The DICOM color model used for the compressed data bitsAlloc - [out] Bits Allocated for one sample bitsStored - [out] Bits Stored, number of bits stored within Bits Allocated highBit - [out] High Bit, hightest bit position set within Bits Allocated pixelRepr - [out] Pixel Representation (0=unsigned, 1=signed) planConf - [out] Planar Configuration pixAspectH - [out] Horizontal value of pixel aspect ratio pixAspectV - [out] Vertical value of pixel aspect ratio pixData - [out] Pointer to the pixel data in JPEG Interchange Format (but without APPx markers). length - [out] Length of pixel data ts - [out] The transfer syntax imposed by the imported pixel pixel data. This is necessary for the JPEG importer that needs to report which TS must be used for the imported JPEG data (ie. baseline, progressive, ...).
- Returns:
- EC_Normal, if successful, error otherwise
Implemented in I2DJpegSource, and I2DBmpSource.
| void I2DImgSource::setImageFile | ( | const OFString & | filename | ) | [inline] |
Sets the input image file to read.
- Parameters:
-
filename - [in] The filename of the image input file
- Returns:
- none
