Problems with overriding image icon in Calibre

infoquake123 · 06-03-2011, 01:03 PM

I posted this a short while ago in the conversion section in my reply to another problem but as this problem does not anything to do with conversion, I have reposted it.

I wanted to overide the image icons used in Calibre. In the manual it says that i should not change the images stored in the resources sub-folder of the calibre install location as my changes will get overwritten the next time I update calibre. And that i should instead, go to Preferences->Advanced->Miscellaneous and click Open calibre configuration directory, create a sub-folder called resources and place the files i want to override in it.

When I went to the open calibre configuration directory, there was already a sub-folder called resources and another folder called images within that. And there was another sub-folder called generate_images within the images folder. As instructed, I placed my images ( that had the same names as the images in the images stored in the resources sub-folder of the calibre install location) , inside the image folder but it did not change the image icons in calibre to mine even after i restarted calibre. Why is this ?

Also, since that did not work, I tried replacing some of the default images in the resources sub-folder of the calibre install location with my images that had the same name . ( I know that the images will be overridden back to the default when i update calibre in future ) That worked for some image icons like library.png and book.png but when i replaced the catalog.png with my own catalog.png, the image icon for the catalog disappeared. Why is this ? Does the pixel size have to be the same or something ?

Also is there any way to change the roman numerals used to show the series info when generating the covers to normal numbers ?

P.S On a separate note, Calibre is an amazing program and i seem to be able do more and more with it as i learn more about it. Kovid, just wanted to let u know that u have done an amazing job.

If you mean the inner subfolder you found was called "generate_cover" rather than "generate_images", this folder is specific to the use of the "Generate Cover" plugin which I suspect you have installed. It would contain any cover images you want that plugin to use, not relevant to what you are trying to do.

Certainly the correct place to put new images you wish to override their Calibre equivalents for is in the \resources\images folder in your local configuration directory as you found through Preferences->Miscellaneous. For any others finding this thread, note that directory will not exist on most people's installations of Calibre, unless they have used a plugin that creates it such as Generate Cover or a few others.

It's a checkbox in Preferences - Look&Feel on the 'Book Details' tab, top right corner
