Option BMP - Bitmap Handling
New with version 3.71: Now with more than 60 supported file formats!
With option BMP bitmap-files can be imported in various formats to serve as background pictures. The most common application is importing scanned maps used as a template for entering sound sources, receiver points and other objects. Furthermore, digital or digitized photographs (orthophotos) in TIFF or JPEG format can be imported.
Scanned bitmap
- Imported bitmap
- Importing geo-referenced bitmaps
- Imported orthophoto as background picture
The number of importable images depends on available memory space and on image resolution. When importing a bitmap file CadnaA references the file name and its path. The bitmap file itself is not stored in the CadnaA file. Even when moving the project file and the bitmap to a different folder on the hard drive, CadnaA will still locate the bitmap file as long as it remains stored together with the project file in the same folder.
Features
- Import of scanned maps of any size
- Shifting, turning and transformation during import ("calibrate bitmap")
- Automatic positioning and geo-referencing (requires coordinates transformation file)
- Size of the bitmap is just restricted by memory space available
- Over 60 supported file formats
