Cutting out images

@@ -6 +6 @@
  1. If there is already an {{{xml}}}-version of the text, it is handy to extract a list of all figures that are to be cut out. You can do this for example by using XQuery in the display system:
 {{{
+//echo:figure
+}}}
+ resp.
+{{{
 //echo:image
 }}}
- Furthermore, you can check (1) if all pages not on that list do not contain images and (2) which pages contain only decorative images.
- 1. Be careful not to cut out surrounding text, including the catchword at the bottom of the page. However, captions are to be cut out, as well. 
+ Depending on how much context you like (with caption or not).
+ 1. Now, in the viewing environment, you can browse through the book, visiting the respective pages and mark the images using digilib's "zoom area" tool. Be careful not to cut out surrounding text, including the catchword at the bottom of the page. However, captions are to be cut out, as well. Some small images are only there for decorative purposes. The policy is not to cut out these ones. Lateron, these have to be deleted out of the xml file.
+ 1. Save the URLs of the pages with the zoomed area into a text file. Also, note in the file which images have to be removed from the XML.
+
+Some steps missing (include creating a script to extract the figures from the raw TIFF files based on the list with the URLs). Also the list should be stored somewhere for future reference (e. g. in case the figures are not produced by cutting the files, but by extracting the figures on the fly). The first list was generated for [http://it-dev.mpiwg-berlin.mpg.de:81/tracs/mpdl-project-content/attachment/wiki/WO3_Apian_1550/Apian_1550_PUBSU9QD_figure-coords.txt Apian 1550].

  1. Save the cropped images again as TIFF in the format {{{page-imagenumber}}}, e. g., if pageimage {{{0056.tif}}} has three figures, these figures will be saved as {{{0056-01.tif}}}, {{{0056-02.tif}}} and {{{0056-03.tif}}}, respectively.
  1. Put the figures into a folder named {{{figures}}} and upload it to the foxridge server alongside the {{{pageimg}}}-folder of the respective book: folder {{{online_permanent/library/XXXXXXXX}}} will then contain both a {{{pageimg}}} and a {{{figures}}} folder.
