Interface DocumentContent

which page to use for the thumbnail

-1 indicates the last visited page, whereas 0 is the first page.

[speculative] various other page metadata

the horizontal center of a customFit zoom

An offset in device pixels from the horizontal center of the page (0 = centered, negative = left, positive = right). This and customZoomCenterY are in the page's own frame, so device orientation does not affect them.

the vertical center of a customFit zoom

An absolute distance in device pixels from the top of the page (negative = up, positive = down); centering is half the page's rendered height.

the orientation the customFit zoom was set in

the rendered height of the pdf page, in device pixels

Computed from the pdf page height in points and the device dpi as heightPt * dpi / 72; the dpi depends on the model (see deviceScreens).

the rendered width of the pdf page, in device pixels

the scale for a customFit zoom

customZoomScale = screenHeight / viewHeight in device pixels, normalized to 1:1 native pixels: at 1 the view is screen-tall, showing screenHeight / customZoomPageHeight of the page. reMarkable generally allows 0.5 to 5, but values outside that bound are still supported.

metadata about the author, publishers, etc.

It's not known what this field is for

the largely contains metadata about what pens were used and their settings

the underlying file type of this document

the name of the font to use for text rendering

The reMarkable supports five fonts by default: "Noto Sans", "Noto Sans UI", "EB Garamond", "Noto Mono", and "Noto Serif". You can also set the font to the empty string or omit it for the default.

the format version, this should always be 1

[speculative] metadata about keyboard use

the last opened page, starts at zero

the line height

The reMarkable uses three built-in line heights: 100, 150, 200, and uses -1 to indicate the default line height, but heights outside of these also work.

the document margin in pixels

The reMarkable uses three built-in margins: 50, 125, 200, but other margins are possible. The reMarkable used to default to margins of 180.

the document orientation

this specifies the number of pages, it's not clear how this is different than pageCount

the number of pages

a list of the ids of each page in the document, or null when never opened

the page tags for the document

a mapping from page number to page id in pages

ostensibly the size in bytes of the file, but this differs from other measurements

text alignment for this document

the font size

reMarkable uses six built-in text scales: 0.7, 0.8, 1, 1.2, 1.5, 2, but values outside of this range are valid.

[speculative] a transform matrix, a. la. css matrix transform

setting for the adaptive contrast filter

off has no background filter, best for images, full page applies the high contrast filter to the entire page. If this is omitted, reMarkable will try to apply the filter only to text areas.

the zoom mode; customFit applies the customZoom* fields, the rest auto-fit
