| | 63 | <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> |
| | 75 | <!-- INDENTATION --> |
| | 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> |
| | 80 | <!-- INDENTATION --> |
| | 81 | <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> |
