Providing native (editable) file formats

To ensure that the IEC figures team can work on the figures in your document, the graphic files need to be in an editable format. This means text and / or lines in the images must be modifiable. The native file format is the most appropriate format for modifications.


What does native file format mean?

Graphic tools are normally able to produce various file formats. For instance, you may work on a diagram in Power Point (when you save your file, the standard format is .ppt or .pptx), or in Visio (then the standard format is .vsd or .vsdx).


This standard format of an application is its native format. If you want to make modifications to the original diagram, you will normally make them in this format.


Therefore it is important that you send us all graphic files in their native format. This allows the IEC figures team to adapt your figures wherever necessary in an efficient way.


Bitmap formats

Drawings, graphs, diagrams etc. can also be saved in a bitmap (=raster) format; various options are normally available under the "save as" (or sometimes "export") menu of image editing tools. Bitmap formats (like .jpg, .tif, .png, .bmp and some others) cannot be edited like the native file format can.


However, as they are independent of the application in which they were created, these formats are well suited for exchanging images. Moreover, the fact that they cannot be modified makes them ideal for use in documents that need to be stable once they are published, such as International Standards.
