| 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>
