Samba is a protocol used for file sharing and is available on many devices. Windows, MacOS, Linux, NAS, Router. It allows you to read Comics in streaming without having to download them first. Streaming is only available in the premium version.

Host name

The ip address or computer name. Preferably use an ip address if the device enters hibernation (NAS).

Username & password

The username and password to access the Samba server.

Path

If the server is accessible and the authentication is valid, you can select a remote path by pressing the folder icon.

When streaming, preferably use a 5G wifi network to reduce latency.

If you enable anonymous mode on Windows, you will still need to specify a username and password in the application. The username must not exist in Windows and must not be “ANONYMOUS”. The password must not be empty, put anything.

This protocol is made to be used in local area network (LAN). If you want to use it on a remote network, I advise you to disable streaming and thumbnails to avoid latency.

Use this protocol to access a remote server, if the server is on a local network, use Samba instead.

The cache size is a very important parameter for devices with little memory and a low resolution screen. To help you choose the right value, here’s how the app uses cache:

In single page mode, the application will cache 4 images, in double page mode it will be 6, the images will be resized to fit in the cache. In continuous reading mode it will be 3 screens and the images will be resized according to the zoom and screen resolution. If you enable 32 bits color, then each pixel will use 4 bytes instead of 2.

ex: 24 MP, 16 bits color mode, Single page mode.

24 MP x 2 Bytes ≈ 48 MB

24 MP = 4 pages x (3029 x 1980)

By default, images are converted to 16-bit color (RGB565), which has the advantage of dividing memory consumption by 2 with imperceptible visual degradation in most cases. You will see a difference in the gradients, if you have a recent device with enough memory, do not hesitate to activate 32-bit true colors.

When the application closes while reading, because it has been in the background for too long or because you have deliberately closed it, then it can be annoying to have to reopen the book you were reading. Activate this option to reopen the book being read when the application is launched.

When the book is opened, the application selects the last page being read.

Prevents the screen from going to sleep while you read.

The app is pre-configured for immersive reading without visual distraction, which is why the notification bar and virtual navigation buttons are hidden by default. Disable this option for a non-immersive mode.

If you have a front-facing camera built into your screen, then part of your screen is unavailable during reading. By activating this option the application will reuse this wasted space.

Some areas where no page is displayed are black. Enable this option to color these spaces using the most common page border color.

A thin dark border is drawn between pages in double-page spread and continuous reading mode. Especially useful for manga.

Attempts to remove empty borders to save space. The proportions of the image are preserved in order not to disturb the fluidity of the display and the transitions.

This finger gesture allows to simulate a horizontal and vertical scroll bar. To use it, double tap the screen and hold your finger on the screen on the second tap. Then move your finger as if moving a scroll bar. This is useful in continuous reading mode or to have a magnifying effect. If you tend to trigger this gesture by mistake, you can simply turn it off.

These options allow you to determine how the app finds the next book to read. These settings affect suggestions and the next book feature in the reader interface.

By default the application uses the series name and the issue number extracted from the filename to find the next book, but sometimes when the naming conventions are not always respected it does not always work. By activating this option the sort is performed on the filename to find the next book.

By default the application searches for the next book in all library folders. This can be a problem when there is another series in your library with the same name but from a different year. By activating this option only the book of the same folder will be selected.

Allow page change by dragging the current page.

Allows page change by touching the screen with a single tap.

After disabling this setting, assign next and previous page actions to the volume buttons.

When the app automatically scrolls to follow the reading flow, the view is moved a distance equal to 100% of the width or height of your screen. Depending on the zoom level, this value is reduced to equalize the distance between scrolls needed to reach the edge of the page. You can reduce this value to avoid too abrupt cuts in the content.

Scroll and page change animations have a duration of 500ms by default. Do not hesitate to adjust this value to have better reading comfort on your device.

Zoom animations have a duration of 500ms by default. Do not hesitate to adjust this value to have better reading comfort on your device.

When reading from right to left, this option reverses the controls you have assigned to areas of the screen.

The screen is divided into nine areas to which you can assign different actions on a single press and a long press.

To avoid touching the screen you can assign controls to volume buttons.

Four additional actions can be assigned on the bar located at the bottom right of the reader.
