addPDFFromFile

Hi, I contributed to the angle rotation on get hub for PNG files. It appears you have extended this to include JPG, but I don't know about GIFs?

This note is to ask about the ability to import a PDF object into a R&OS object. I can do this in Latex no problem... Similar to embedding images (PNG, GIF, JPG), I want to embed a PDF ... and probably with "clip options" - below is the syntax for latex...

\includegraphics[trim = 0 0 0 0,clip,width=6.5in]{pdfs/sample_growth.pdf}

@MonteShaffer not quite sure yet but I guess gif will be converted into png. So I assume everything that is possible with png should also be possible with gif?!

We are going to work on this, and provide a function if we can solve the problem.

PDFs are a collection of objects... and a PDF object could exist in the master PDF object. This is something I use all of the time with latex ...

PNG / GIF / JPEG are expensive since they have to load all the binary data in. A PDF object is not very expensive because it may contain vectorized data.

Specifically, I can export a HighCharts graph as a PNG or PDF. The file size is 48KB and 17KB respectively for a test case. Building in Latex, the with a reduced-size image, the file size is 45KB and 29KB respectively. So it can be done. If I were to bump up the PNG size, the entire file size would keep getting bigger, but the PDF version will remain pretty much unchanged (if the PDF has vectorized elements).

Anyway, we will play around and see if we can come up with a function ... addPdfFromFile

IMAGES basic.pdf

LATEX-BUILDS hello-pdf.pdf hello-png.pdf

ROS BUILDS hello-pdf.pdf hello-png.pdf

Currently ROS build for hello-pdf.pdf fails since it doesn't have a way to read the stream in correctly... If you want to take a stab at this, please let me know.

The 1.3 specification is above...

Latex is running on the 1.5 spec ... Below is the Latex code, and /PTEX.FileName (./graphs/basic.pdf) is not a 1.3 command ...

So can we push development forward to be at least 1.5 compliant ...

I don't see PTEX here either... In latex I am using the graphicx package ... maybe this is a psuedo tag it generates...

Honestly, I would like to see a push to at least 1.7 compliant... as I believe it has "annotation" features...

honestly I would prefer to use the experimental for this, as this already supports import PDF feature.

[MonteShaffer]

ok. is "experimental" basically functional? I see "annotations", but I don't see "import PDF"...

[ole1986]

There is a class CpfPdi available for import... But you know it's experimental...
