gold Started roughly 2011-05-28. Here is an eTCL script to estimate timing photo image loading under pixane.
This script was largely derived from posting of Eric Hassold on comp.lang.tcl with permission. The timing statements were pulled from the program below after the timing info was calculated. The impetus for the script was an ask9 question about time of "loading single image ...". My solution to a different application on Unix some grey hairs ago was creating batch thumbnails with Image Magick, before loading the application script. If one can work with thumbnails, a tcl or perl script can use Image Magick to thumbnail every image in a directory or tailor to specific megabyte size. Since now, I'm using etcl and pixane on an Acer Aspire pc notepad, it might be desirable to establish some peg points or timing results with the pixane image library. The timing results with pixane are similar to those reported for Image Magick on a Pentium, Fast image resizing.
In planning any software, there is a need to develop testcases.
Output of timing statements.
| quantity | number | units |
|---|---|---|
| photo size of bird.jpg | 1.6 | m |
| loading | 1595970 | microseconds per iteration |
| Scaling | (1944 x 2592) => (180 x 240) | pixels |

| blanking | 4283 | microseconds per iteration |
| rescale | 230934 | microseconds per iteration |
| saving | 14458 | microseconds per iteration |
| proc time | 1863222 | microseconds per iteration |
