Save Raster Image

WinTopo provides many features for modifying a raster image, so as to improve the results of the vectorisation process. If you have used these features you may wish to save a copy of the modified raster image.

On the File menu you can select either Save Image to overwrite the original file, or Save Image As... to select a new name for the raster file.

Save As window

Files can be saved as either:

BMP - Windows Bitmap
TIF - Tagged Image File Format
PNG - Portable Network Graphic
JPG - Jpeg Image Format

Use the Save as type: option on the window to choose which file format you want to save the raster in. TIF or PNG files are recommended because they will always be much smaller than BMP files.

Remember that although JPG generally makes the smallest files, it is a lossy file format and therefore most use for photographic images rather than drawings. Avoid using JPG for images that you want to convert to vector. The JPG compression algorithm introduces false details, as well as losing real detail.

Enter the name you want for the raster file against the File name prompt.
