Image conversion tables
 
This table shows whether or not image conversion takes place when an image is stored in a TreePad database, whether as a result of being imported or copied⁄moved within the TreePad file.
 
Image storage conversion
Image format When Inserted1, stored as When Pasted2, stored as
BMP BMP BMP
EMF EMF EMF⁄WMF
GIF GIF BMP
ICO ICO BMP
JPG JPG BMP
PNG PNG BMP
WMF WMF EMF⁄WMF
 
 
This table shows what image conversion is applied when an article containing images is exported to a Web page (or a subtree exported to a Website).
 
Image export (to Website) conversion
Image format as stored
Exported to Website4+ as
BMP JPG
EMF GIF
GIF GIF
ICO GIF

PNG PNG
WMF GIF
 
 
See Image filetypes supported for an explanation of these image formats.
 

 
Notes:
 
  1. Note that when Insert ⁄ Image(s) from file (column 2) is used, all images are imported in their native (original) formats.
  2. "When Pasted" is used here as an abbreviation for "When Copied⁄Pasted", as described in Cutting, Copying and Pasting images into an article.
  3. Copy⁄Paste pastes all pixel type image formats (BMP, GIF, ICO, JPG and PNG) as BMP images, thus converting their formats. Vector image formats (EMF and WMF are stored in their own format.
  4. JPG is a lossy format but results in small image files, so formats with large files such as BMP are converted to JPG, while JPG being a Web format can be exported unchanged, which avoids further image degradation.
  5. GIF is non-lossy, except for the color information, therefore vector and icon images are exported as GIF.
  6. BMP, ICO, EMF and WMF are not Web formats and are not supported by non-Windows browsers, so need to be converted when exported to a Website.
  7. PNG, GIF (and JPEG) are also Web image formats, so are not converted but exported unchanged.
