Img2Ozf

Program History

Version 2.08

Fixes

• When using a "Large Font" display setting in Windows the image thumbnail view window was positioned incorrectly.
• Map files with more than one dot (.) in the file name were not being handled correctly.
• some other minor fixes.

Changes

• Improved the loading of bmp image files, RLE compressed images can now be loaded.
• Made some changes to the code so Img2ozf will run on win95 PC's without having to install the latest version of DCOM (a Microsoft download).
• The image file list will not be filled when the program first starts. The list can take considerable time to fill if there are a lot of files in the "Source Image Folder". While the list is filling there is nothing shown on the screen and users may think there is something wrong. To fill the list using the current "Source Image Folder" press the refresh button after the program starts.

Version 2.07

Fixes

• Images greater than 32,000 x 32,000 pixels could not be processed, this was cause by a static variable which has now been made dynamic (so it can grow) which has fixed the problem.
• Minor fix to the way map files are modified - under certain conditions a map file could get a reference to the wrong image.

Changes

• The Destination and Temp folders are checked to make sure they are not on a CDROM
• Images that are less than 300 pixels in both width and height cannot be converted and would cause an error, this is now checked, they are not processed and an error message is generated in the log.

Version 2.06

Fixes

• the black and white colors are always added to the palette when images are resized or colors reduced, the white color was not being included, now fixed.
• The search for the map file was a little broken, it still worked but did not search for sub-folders in the "Map File Path" correctly.

Changes

• added ascending and descending sort when the column headers are clicked
• add ozf2 file size and path to the process log
• added the ability to copy the process log to the clipboard

Version 2.05

Fixes

• The MSF factor was being written to the map file incorrectly if the decimal separator for your country setting is a comma, now fixed.
• Fixed the popup hint for the "Number of Colors" checkbox.

Changes

• nil

Version 2.04

Fixes

• nil

Changes

• Changed the 20% zoom level to 25% - we felt that the zoom gap between 40% and 20% was too large and 25% is a better compromise. The gap between 25% and 10% is now larger but this is not as much of a problem.
• Added a button to refresh the image list.

Version 2.03

Fixes

• nil

Changes

• Added the ability to specify the number of colors to use in the converted image.

Version 2.02

Fixes

• The "Map Scale factor" (MSF command) was being added to the .map files even though the "Initial Resize" was not checked.
• other minor fixes.

Changes

• nil

Version 2.01

Fixes

• When using win 95, 98, ME and converting SID images the ozf2 files were upside down. I have fixed this (I hope).

Changes

• Added paged support for tif files.
• The conversion log no longer pops up automatically, there is now a button to show the log.
• Made some subtle changes to memory management to try and reduce memory fragmentation so many very large files can be converted in the same session. This may not work as windows controls its own virtual memory.

Version 2.00

Changes

There has been a complete rewrite of Img2Ozf resulting in at least these changes.

• Reduced memory requirements when converting images.
• Where possible the image is paged from disk and only a few megabytes of memory is required.
• Ability to resize an image before creating the OZF2 file.
• There is no longer the ability to select the zoom levels to be placed in the image. Zoom levels of 75% and 50% (+ additional zoom levels) are now generated "on the fly" by OziExplorer and OziExplorerCE. The zoom levels of 20% and below are automatically added to the image as they add very little to the overall size.
• The ability to create OZF files is no longer supported, this format now offers no advantages over the OZF2 format.

Version 1.43

Fixes

• nil

Changes

• 24 bit color and Grey Scale png files can now be loaded.
• Support for converting Maptech HDR (PCX) and RML charts.
• Added the ability to sharpen the zoom levels. There is a checkbox to turn sharpen on or off.

Version 1.41

Bugs

• Fixed loading of some types of png files.

Changes

• 24 bit color tiffs can now be loaded.

Version 1.40

Bugs

• The previous version was adding image fragments to the right and bottom of the converted ozf2 image. These additional image parts were not pleasing to look at but caused no problems for OziExplorerCE (other than visual ones). The additional part of the image needs to be there but is now blanked as the image is converted so it is not visible.
• The conversion of colors for some types of PNG files has finally been found and fixed (I hope).

Changes

• Changes have been made to memory management so larger images can be converted.
• The MrSID format has been added and can be converted. You meed the OziMrSID.dll which is available on the web site. It may be available from the development version page.
• User feedback has been added to the status line so you can see how the conversion is progressing.
• Img2ozf now has its own help.
