The solutionД«efore converting each DWG file to PDF, we convert seamlessly and without user interaction any Arabic text from its standard representation to the Arabic Presentations Form-B representation.ДЄnd after producing the PDF, we rollback any changes to the DWG file, so that users can benefit from the simpler input in the standard representation.

Since it has no ligatures, it means that the visual representation is going to be the same in AutoCAD softwareДЄs in the resulting symbol-wise representation in the final PDF files. The latter is deprecated because it has limitations in how text is represented (it has no concept of ligatures).Д«ut this case is precisely where it is supposed to be used. Unicode is an attempt to standardise text encoding and representation.Д«asically, it sets the rules to how computers save and interpret text.ДЇor Arabic we are aware of two main Unicode blocks: This sounds alright, but it canвЂ™t be automated and is error prone. Importing/exporting: AutodeskВ® design review can do transparencies to XPS, which can in turn be converted to a rasterised PDF without losing the ligatures.It also requires implementing a special workflow to merge the resulting PDF files. However it is not elegant, requires heavy pre-processing of each DWGВ® file and at least it doubles file processing time. Assuming text goes above everything else, this might be an interesting approach. Generate two PDF files: one with texts, one without texts.Exploding text to geometry: this works on a per-symbol basis, ignoring ligatures, which means the visual result is still wrong.

Knowing what not to do is sometimes as important as knowing what to do. Which means that printing from AutoCAD with transparencies enabled removes ligatures always, and is fairly visible in languages like Arabic. Sadly, dealing with these ligatures in a pixel-wise fashion is pretty difficult and the lovely people at Autodesk havenвЂ™t yet managed to make it work. Languages like Arabic on the other hand donвЂ™t have this luxury.ДЇor example: words like Ш§Щ„ШЩѓЩ€Щ…ЩЉ or пєЌп»џпєп»ЊпєЌп»п»§п»° turn into Щ„ Ш Щѓ Щ€ Щ… ЩЉ or Щ„ ШЄ Ш№ Ш§ Щ€ Щ† Щ‰ without ligatures which is unreadable for speakers of Arabic. In Roman alphabet-based languages, this is not much of an issue, since a lack of ligatures keeps text readable. a ffinity uses a ligature to have a nicer typographical representation of ff. The main issue here are ligatures, in languages that use the Roman alphabet, this isnвЂ™t that much of an issue, but we do use them a lot. That means things have to be done pixel-wise, and with texts things get tricky again. Then draw the elements вЂњbottom to top** and apply the percentage of the level of opacity as a weighted average. The way transparencies are handled traditionally is to assign each element a colour and a level of opacity.

This is the case with transparencies, which are not fully supported in PDF files or by printers, and certainly not in all cases where AutoCAD software can use them. The latter means that we only save the starting point, the end point and the colour, which allows us to derive the pixel-wise data.Д¬learly vector form graphics are more accurate and require less storage, but in order to represent graphics on a screen, or on paper (even digital like PDF), we sometimes need to rasterise or convert data to pixels. Raster or pixel-wise means that in order to represent a line, we save the colour of all pixels (or squares) where the line passes through.

Traditionally there are two ways of representing things: raster or pixel-wise and in vector form. What is happening? (and why?!) Transparencies and computersД¬omputer graphics are a tricky issue (we should know!).
