Dear list, The other day I asked for info. on color support with raster images (see below). "Can anyone give me the "lowdown" on MapInfo V4 & V5 support for 24 bit color and adjusting the registry." The main response I received was that the release of MapInfo V5.5 will feature "Support for 24-bit Color including transparency, brightness, contrast, greyscale" We are just moving to MapInfo V5.01! So being able to switch between modes is still an issue. As I mentioned in my original message. "Unfortunately the IT dept. in my company locks me out of adjusting any registry settings. Is there any other method to change these settings??" To fix the editing of my inaccessible registry one of our support people (thanks Kyle Morris) has written two (.REG) files which can change the key by running either one or the other. They are text files and contain the following : MapInfo UseTrueColor 24bit.reg (file name) REGEDIT4 ; ; This seting allows the user to stop/start the MapInfo graphics ; engine dithering 24bit images down to 8bit ; the possible values are as follows : ; UseTrueColor=0 [dither 24bit down to 8bit] ; UseTrueColor=1 [display 24bit images in TrueColor] ; ; [HKEY_LOCAL_MACHINE\SOFTWARE\MapInfo\MapInfo\Common] "UseTrueColor"=dword:00000001 MapInfo UseTrueColor 8bit.reg (file name) REGEDIT4 ; ; This seting allows the user to stop/start the MapInfo graphics ; engine dithering 24bit images down to 8bit ; the possible values are as follows : ; UseTrueColor=0 [dither 24bit down to 8bit] ; UseTrueColor=1 [display 24bit images in TrueColor] ; ; [HKEY_LOCAL_MACHINE\SOFTWARE\MapInfo\MapInfo\Common] "UseTrueColor"=dword:00000000 The MBX applications "colorsupport" http://www.mapONE.com & MapImagery http://www.gid.com do switch between 24 & 8 bit, but only when you have access to the registry. This now leads me to another response I have received and this is that the 24 bit raster does NOT work in 5.5 as stated. This has apparently been proven by on of our resellers "Desktop Mapping Systems" here in Perth. Can anybody comment on this? One other thing. If MapInfo has 24 bit enabled, it appears to still print the image dithered? This was tested with an aerial photograph scanned at 150dpi, 24 bit in tif format. Has anyone else found this happens?
