顯示.pdf文件時,Kindle Paperwhite 2上可視區域的原始像素分辨率是多少?



我的目標是生成文件,在顯示時,它們以1:1,逐像素的方式呈現,以確保文本的最大清晰度。在k2pdfopt程序的GUI版本中提供的值似乎不正確,並且在設備上顯示時會產生明顯降級的結果。

當然,這應該排除屏幕底部的鉻和繪制的任何邊距。另外,防止軟件自動縮放圖像的手段對於了解是有用的。

To prevent the images from scaling you should set the width of the image in pixels rather than in, eg, 100%. It appears that the Kindle Paperwhite is 4.6 inches wide at 212 ppi (source), which comes to an unlikely 975.2 pixels wide—but it's a place to start. I would suggest setting image width (or width of containing div) to 970 px for starters. If it's distorted, then there is probably a hard-coded margin for the page of greater than 2 pixels, so reduce a small amount and try again.

Note that specifying the pixel size will mean that on other Amazon devices, the image will not resize to fit the screen—iPad and iPhone Kindle app users may not be happy with the end result.

Calibre將paperwhite列為像素數為658 x 940,並將paperwhite 3列為屏幕尺寸為1072 x 1430。
