Question:I want to convert PDF to SVG please suggest some libraries/executable that will be able to do this efficiently. I have written my own program using some libraries. This solution works great but the size of the resulting SVG files in huge.(many times greater than the pdf). I have figured out where the problem is by looking at the SVG in a text editor. it encloses every character in the original document in its own block even if the font properties of the characters is the same. For example the word hello will appear as 6 different text blocks. Is there a way to fix this matter in VeryDOC?
