I need a way to wrote code to read through a pdf and change the chart bar color (when it is brown, I need to change it to orange) and was wondering if there were an SDK with that cabilities. I would like to automate this with some 'C' language so I could launch this after another application.
In the PDF, the bar chart is not identified as such – it is just a set of drawing instructions. That said, if you can identify the use of color (perhaps it’s the only time brown is used on the page) – then you can change the color to anyting you want by changing the operators used.
This will require writing a custom plugin (in C/C++) based on the Acrobat SDK.
