<p><i>TIFFDefaultStripSize</i> returns the number of rows |
|
64 |
for a reasonable-sized strip according to the current |
|
65 |
settings of the <i>ImageWidth</i>, <i>BitsPerSample</i>, |
|
66 |
<i>SamplesPerPixel</i>, tags and any compression-specific |
|
67 |
requirements. If the <i>estimate</i> parameter, if non-zero, |
|
68 |
then it is taken as an estimate of the desired strip size |
|
69 |
and adjusted according to any compression-specific |
|
70 |
requirements. The value returned by this function is |
|
71 |
typically used to define the <i>RowsPerStrip</i> tag. In |
|
72 |
lieu of any unusual requirements <i>TIFFDefaultStripSize</i> |
|
73 |
tries to create strips that have approximately 8 kilobytes |
|
74 |
of uncompressed data.</p> |
|

|
76 |
<p><i>TIFFStripSize</i> returns the equivalent size for a |
|
77 |
strip of data as it would be returned in a call to |
|
78 |
<i>TIFFReadEncodedStrip</i> or as it would be expected in a |
|
79 |
call to <i>TIFFWriteEncodedStrip</i>.</p> |
|

<!-- INDENTATION --> |
|

<p><i>TIFFVStripSize</i> returns the number of bytes in a |
|
82 |
strip with <i>nrows</i> rows of data.</p> |
|
83 |
<!-- INDENTATION --> |
|
84 |
<p><i>TIFFRawStripSize</i> returns the number of bytes in a |
|
85 |
raw strip (i.e. not decoded).</p> |
|
86 |
<!-- INDENTATION --> |
|
87 |
<p><i>TIFFComputeStrip</i> returns the strip that contains |
|
88 |
the specified coordinates. A valid strip is always returned; |
|
89 |
out-of-range coordinate values are clamped to the bounds of |
|
90 |
the image. The <i>row</i> parameter is always used in |
|
91 |
calculating a strip. The <i>sample</i> parameter is used |
|
92 |
only if data are organized in separate planes |
|
93 |
(<i>PlanarConfiguration</i>=2).</p> |
|
94 |
<!-- INDENTATION --> |
|
95 |
<p><i>TIFFNumberOfStrips</i> returns the number of strips in |
|
96 |
the image.</p> |
