sizeInPixels :: ImageSize -> (Integer, Integer) Source #

sizeInPoints :: ImageSize -> (Double, Double) Source #

Calculate (height, width) in points using the image file's dpi metadata, using 72 Points == 1 Inch.

desiredSizeInPoints :: WriterOptions -> Attr -> ImageSize -> (Double, Double) Source #

Calculate (height, width) in points, considering the desired dimensions in the attribute, while falling back on the image file's dpi metadata if no dimensions are specified in the attribute (or only dimensions in percentages).

data Direction Source #

Constructors

Width 
Height 

dimension :: Direction -> Attr -> Maybe Dimension Source #

Read a Dimension from an Attr attribute. `dimension Width attr` might return `Just (Pixel 3)` or for example `Just (Centimeter 2.0)`, etc.

scaleDimension :: Double -> Dimension -> Dimension Source #

Scale a dimension by a factor.

numUnit :: String -> Maybe (Double, String) Source #

Maybe split a string into a leading number and trailing unit, e.g. "3cm" to Just (3.0, "cm")

showInInch :: WriterOptions -> Dimension -> String Source #

Convert a Dimension to a String denoting its equivalent in inches, for example "2.00000". Note: Dimensions in percentages are converted to the empty string.

showInPixel :: WriterOptions -> Dimension -> String Source #

Convert a Dimension to a String denoting its equivalent in pixels, for example "600". Note: Dimensions in percentages are converted to the empty string.
