Storage of images in their native format
When importing images into the article using Menu⁄insert⁄image(s) from file, the image is always imported and stored in its native format, just as if you added it to a zip file, without conversion or loss of information.
This means that when you import an image, and later on export it to the same file format, no loss will occur and the exported image is exactly the same as the file which was originally imported. When you export to HTML or Website, images might get exported to a different format (conversion):
- BMP images are converted to JPEG when exported
- EMF⁄WMF and ICO images are exported as GIF
- Other image formats are not converted during export to HTML or Website: PNG, GIF and JPEG
If you frequently export to HTML or Website, the best format to store images is PNG, because PNG images are compressed without any loss of information, the compression method for PNG is very efficient, and PNG is an Internet image format, so TreePad does not convert PNG images to another format during export to Website or HTML.
Please note that images added to a TreePad database through Copy⁄Cut⁄Paste are stored as BMP or EMF. The reason for this is that these are the formats the Windows clipboard supports.
Note that you can also export images to a variety of formats of your own choice.
