KeyNote NF (New Features) Files

This new release corrects many issues, and includes also important improvements.

A summary of the main changes included throughout the last six beta versions (1.8.0 Beta 1 - 1.8.0 Beta 6) is available in 'history.txt' and more detail in 'Changes in 1.8.0 Beta1-6.txt' This beta releases has been available in issue [#602], and tested by several persons, on different Windows versions: W10, W11 and even W7 (with RichEdit 4))

Please, see the file "BetaReleases_README.txt" for information about how to install or update this Beta release.

And remember: It is always strongly recommended to conserve backups of .knt files, specially before upgrading to a new version.

NOTE - Insertion of images: The problems described in issue [#574], and related to [#568], were most likely due to a bug present in older versions of the RichEdit control, when processing images saved internally in png (\pngblip) format. When I analyzed that problem back in the day, I already noticed anomalous behavior also from the WordPad application (also based on the RichEdit control).

From the tests I have been currently doing, specifically on a file with some images that once caused this problem (a bug that I could force without excessive difficulty by doing different copy, paste, etc. operations), it seems that this problem no longer exists. Current versions of the RichEdit control appear to handle these images correctly, and I have not been able to reproduce the error.

I therefore believe that currently (in current versions of Windows, on W10 or W11) there should be no problem using images in KeyNote. Of course, being aware of the increase in file size that the use of images can entail. And of course ensuring you have backup copies (see the options available in KeyNote, especially 'Backups at regular intervals') I recommend looking at the document "Comments on KNT file formats.txt", where I included some tests comparing sizes and times, considering also the use of images.

The next improvement that I will incorporate to KeyNote will be aimed at improving image management, avoiding the problem of excessive size.

Images JPEG, PNG, GIF, TIFF, BMP Note that in current versions of the RichEdit control it is possible to drag an image file into the editor (from the file explorer, for example) of any of the formats listed above. In these cases, the RichEdit control will save the image in a more optimized RTF format (the file will take up less space). It will still save the image as ASCII in hexadecimal format, but in many cases it will do so once compressed to JPG or PNG:

• PNG, GIF, BMP, TIFF => png format (\pngblip)
• JPG => jpg format (\jpegblip)
• Capture from clipboard => windows meta file format (WMF) (\wmetafile8)

This last format was the only one recognized by older versions (e.g., version 4, available in XP or W7), and it takes up much more size than the rest (png or jpg).

Important Insert | Picture... is currently not recommended. Can still be used to insert .bmp images, but NOT for other types of images. (The latter cause an exception and the closing of the program!) It is currently highly recommended not to use this function but to drag the image files to the editor. Images (BMP) included via Insert | Picture... are inserted through the clipboard, therefore saved in WMF.
