H5IM_MAKE_IMAGE_8BIT

Creates and writes an image.

Procedure:

H5IM_MAKE_IMAGE_8BIT(loc_id, dset_name, width, height, buffer)

Signature:

herr_t H5IMmake_image_8bit ( hid_t loc_id, const char *dset_name,  hsize_t width, hsize_t height, const unsigned char*buffer)

subroutine h5immake_image_8bit_f(loc_id, dset_name, width, height, buf, errcode)
  implicit none
  integer(HID_T), intent(IN) :: loc_id           ! file or group identifier 
  character(LEN=*), intent(IN) :: dset_name      ! name of the dataset 
  integer(HSIZE_T), intent(IN) :: width          ! width of image  
  integer(HSIZE_T), intent(IN) :: height         ! height of image
  integer*1, intent(IN), dimension(*) :: buf     ! 1 byte integer data buffer 
  integer :: errcode                             ! error code
end subroutine h5immake_image_8bit_f

Parameters:
hid_t loc_idIN: Identifier of the file or group to create the dataset within.
const char *dset_nameIN: The name of the dataset to create.
hsize_t widthIN: The width of the image.
hsize_t heightIN: The height of the image.
const unsigned char *buffer    IN: Buffer with data to be written to the dataset.

Description:

H5IMmake_image_8bit creates and writes a dataset named dset_name attached to the file or group specified by the identifier loc_id. Attributes conforming to the HDF5 Image and Palette specification for an indexed image are attached to the dataset, thus identifying it as an image. The image data is of the type H5T_NATIVE_UCHAR. An indexed image is an image in which each each pixel information storage is an index to a table palette.

Returns:

Returns a non-negative value if successful; otherwise returns a negative value.

Example:

main (void)
{
    hsize_t     dims[2], dimsm[2];   
    int         data[DIM0][DIM1];           /* data to write */
    int         sdata[DIM0_SUB][DIM1_SUB];  /* subset to write */
    int         rdata[DIM0][DIM1];          /* buffer for read */
 
    hid_t       file_id, dataset_id;        /* handles */
    hid_t       dataspace_id, memspace_id;
