 ## FAQ
+- Should I use Calibre?
+  - No. Calibre doesn't properly support fixed layout EPUB/MOBI, so modifying KCC output in Calibre will break the formatting.
+    Viewing KCC output in Calibre will also not work properly.
+    On 7th gen and later Kindles running firmware 5.15.1+, you can get cover thumbnails simply by USB dropping into documents folder.
+    On 6th gen and older, you can get cover thumbnails by keeping Kindle plugged in during conversion.
+    If you are careful to not modify the file however, you can still use Calibre, but direct USB dropping is reccomended.
+- What output format should I use?
+  - MOBI for Kindles. CBZ for Kindle DX. CBZ for Koreader. KEPUB for Kobo.
 - All options have additional information in tooltips if you hover over the option.
 - To get the converted book onto your Kindle/Kobo, just drag and drop the mobi/kepub into the documents folder on your Kindle/Kobo via USB
+- Right to left mode not working?
+  - RTL mode only affects splitting order for CBZ output. Your cbz reader itself sets the page turn direction.
 - Colors inverted?
  - Disable Kindle dark mode
 - Cannot connect Kindle Scribe or 2024+ Kindle to macOS

 - How to make AZW3 instead of MOBI?
  - The `.mobi` file generated by KCC is a dual filetype, it's both MOBI and AZW3. The file extension is `.mobi` for compatibility reasons.

- [Flatpak mobi conversion stuck](https://github.com/ciromattia/kcc/wiki/Installation#linux)
 - Image too dark?
  - The default gamma correction of 1.8 makes the image darker, and is useful for faded/gray artwork/text. Disable by setting gamma = 1.0
- [Better PDF support (Humble Bundle, Fanatical, etc)](https://github.com/ciromattia/kcc/issues/680)

Its-my-right	cc2eb9dcf3	Feature/rainbow eraser for color images (#1034 ) * Add rainbow_artifacts_eraser helper This helper file contains the methods necessary to perform a fourier transform on the picture, to remove frequencies responsible for rainbow artifacts on Kaleido screens, and performe the reverse fourier transform * Replace blurring method with frequency removal method to erase rainbow effect on Kaleido 3 screens * High performance improvements by using rfft2 instead of fft2 * Fine-tuned the settings and added the perpendicular direction for a better final rendering The finer settings allow for more information to be retained in the final image, while still effectively removing the rainbow effect. Adding the perpendicular direction results in a better rendering of the final image (avoiding visual artifacts related to suppression at the main angle). * Revert the addition of perpendicular angles and lower attenuation_factor It was a mistake to add the perpendicular angles in the previous commit: I had the rainbow effect removal process called 2 times when I did this, for testing purposes (One before downscale and one after downscale). The proper way to call the process is only after the downscale. And in this case it is not necessary to remove frequencies along the perpendicular angles. In the mean time, attenuation_factor=0.15 has proven to work well along a collection of testing images. It should be my latest commit for this feature * Also attenuate high frequencies at 45° CFA is sometimes orientated at 135°, sometimes at 45° so until we find if there is a law depending on the screen size, e-reader model or something, the best we can do is attenuate high frequencies on those two directions * fix imports * Update comic2ebook.py Calculate is_color with (opt.forcecolor and img.color) pass is_color to img.optimizeForDisplay * Update image.py Remove color check condition, because now we process colored images too. Pass is_color to erase_rainbow_artifacts * Update rainbow_artifacts_eraser.py Add support for colored images: Convert to YUV, extract luminance channel, do FFT -> Filter -> IFFT on luminance channel, insert back to YUV, convert back to RGB To maximize compatibility until we know for sure the orientation of CFA for each device, filtering is now done on 135° + 45° axis After more testing, attenuation_factor is decreased to 0.10 * Update comic2ebook.py Rename rainbow eraser param * Update image.py rename rainbow eraser param * Update KCC.ui Rename rainbow eraser checkbox and tooltip * Update KCC_ui.py Rename erase rainbow checkbox and tooltip * Update KCC_gui.py Rename erase rainbow checkbox and option * Update README.md rename erase rainbow param * Update KCC_gui.py correct param name for eraserainbow --------- Co-authored-by: Alex Xu <alexkurosakimh3@gmail.com>	2025-07-18 10:48:56 -07:00
