  26. .SH NAME
  27. TIFFWritedEncodedStrip \- compress and write a strip of data to an open
  28. .SM TIFF
  29. file
  30. .SH SYNOPSIS
  31. .B "#include <tiffio.h>"
  32. .sp
  33. .BI "tsize_t TIFFWriteEncodedStrip(TIFF *" tif ", tstrip_t " strip ", tdata_t " buf ", tsize_t " size ")"
  34. .SH DESCRIPTION
  35. Compress
  36. .I size
  37. bytes of raw data from
  38. .I buf
  39. and write the result to the specified strip; replacing any previously written
  40. data. Note that the value of
  41. .I strip
  42. is a ``raw strip number.'' That is, the caller must take into account whether
  43. or not the data are organized in separate planes (\c
  44. .IR PlanarConfiguration =2).
  45. .SH NOTES
  46. The library writes encoded data using the native machine byte order. Correctly
  47. implemented
  48. .SM TIFF
  49. readers are expected to do any necessary byte-swapping to correctly process
  50. image data with BitsPerSample greater than 8.
  51. .PP
  52. The strip number must be valid according to the current settings of the
  53. .I ImageLength
  54. and
  55. .I RowsPerStrip
  56. tags.
  57. An image may be dynamically grown by increasing the value of
  58. .I ImageLength
  59. prior to each call to
  60. .IR TIFFWriteEncodedStrip .
  61. .SH "RETURN VALUES"
  62. \-1 is returned if an error was encountered. Otherwise, the value of
  63. .IR size
  64. is returned.
  65. .SH DIAGNOSTICS
  66. All error messages are directed to the
  67. .IR TIFFError (3TIFF)
  68. routine.
  69. .PP
  70. \fB%s: File not open for writing\fP. The file was opened for reading, not
  71. writing.
  72. .PP
  73. \fBCan not write scanlines to a tiled image\fP. The image is assumed to be
  74. organized in tiles because the
  75. .I TileWidth
  76. and
  77. .I TileLength
  78. tags have been set with
  79. .IR TIFFSetField (3TIFF).
  80. .PP
  81. \fB%s: Must set "ImageWidth" before writing data\fP.
  82. The image's width has not be set before the first write. See
  83. .IR TIFFSetField (3TIFF)
  84. for information on how to do this.
  85. .PP
  86. \fB%s: Must set "PlanarConfiguration" before writing data\fP.
  87. The organization of data has not be defined before the first write. See
  88. .IR TIFFSetField (3TIFF)
  89. for information on how to do this.
  90. .PP
  91. \fB%s: No space for strip arrays"\fP.
  92. There was not enough space for the arrays that hold strip offsets and byte
  93. counts.
