How to scale an external figure from lua ?
Dear all, I am trying to write some lua code that loads some pdf file and scales it. I have the following code (got from previous question here to get number of pages from a pdf and from source files). local figure = figures.push { name = filename, scale = N } -- scale value does not seem to be taken in account assert(figure, 'Could not load figure from file ' .. filename) figures.identify() figures.check() figures.dummy() -- needed ? figures.scale() -- how to pass the scaling factor ? local d = figures.done() print('Scales ' .. figure.status.xscale .. ' ' .. figure.status.yscale) -- outputs Scales 1 1 figures.pop() Hoping that’s possible to do in lua code and my questions are not too dumb (still a beginner in ConTeXt). Many thanks for your help, Best regards JC
More precisely, I would like to get width and height of the scaled figure Inside lua code, to perform some checks.
