Requested Increase Number of EXIF fields in Full Screen View

[gt13013]

Hi,

I am using the customizing feature of IrfanView in order to choose the Exif fields that I want to see on the Full Screen View.
Today, I tried to add some fields, but it seems that there is a limitation somewhere.
For instance, in

Options > Properties/Settings > Full screen / Slideshow > Full screen only

if you put :

$D$F $X
$E271 - $E272
DateTimeOriginal: $E36867
DateTime: $E306
$E33434
$E33437
ExposureProgram: $E34850
ExposureMode: $E41986
ISOSpeedRatings: $E34855
ISO Value (Canon): $E16
GainControl: $E41991
ShutterSpeedValue: $E37377
ExposureBiasValue: $E37380
MeteringMode: $E37383
LightSource: $E37384
$E37385
FocalLength: $E37386
FocalLengthIn35mmFilm:$E41989
DigitalZoomRatio:$E41988
CustomRendered: $E41985
WhiteBalance:$E41987
SceneCaptureType: $E41990
----
$I

then it works fine.
But if you add some fields, for instance :

$D$F $X
$E271 - $E272
DateTimeOriginal: $E36867
DateTime: $E306
$E33434
$E33437
ExposureProgram: $E34850
ExposureMode: $E41986
ISOSpeedRatings: $E34855
ISO Value (Canon): $E16
GainControl: $E41991
ShutterSpeedValue: $E37377
ExposureBiasValue: $E37380
MeteringMode: $E37383
LightSource: $E37384
$E37385
FocalLength: $E37386
FocalLengthIn35mmFilm:$E41989
DigitalZoomRatio:$E41988
CustomRendered: $E41985
WhiteBalance:$E41987
SceneCaptureType: $E41990
----
$I
----
Nikon specific
ISO Setting: $E2
White Balance: $E5
Focus Mode: $E7
Lens Type: $E131
Lens: $E132

the last fields are not taken into account.
It seems that Irfanview has some limitation here.
I have not seen anything about this problem in the help nor in the forum.

I use the 4.25 version.

Probably no one else ever tried to use so many fields. There is bound to be a limit for most things. How many bytes should the programmer assign for storing this info? Enough for 256 characters, 1024, 16.7 million? I guess the programmer thought that 99.99% of people would be happy with whatever limit he chose.

That is what I suspected.

Consequently, I turn my observation into a suggestion:
could the programmer increase the number of fields in his next compilation of the code ?

Thanks

Take a page from GraphicConverter X

I suggest making some use of the area below the image. GraphicConverter X on the Mac side has done so since before there was an OS X.

One link to acquaint you with the method/approach/way-it's-done in Hr. Lemke's program:

http://www.lemkesoft.com/content/148/slide-show-functions-mac-picture-viewer-mac-image-viewer.html

In the first graphic, between the pull-down menu marked "Original Size" and the checkbox marked "Ignore alpha channel," you'll notice a button marked "Select Information." This brings up another prefs window with a sizeable list of fields one can choose from. I'm sure since the versions I used (all ending in 2008 when my G4 lost its power supply), that some EXIF has been added, but I normally paid attention only to the IPTC fields one could add along the bottom of the fullscreen display. Typically the slideshow function afforded one (at most) four lines of approximately 80-150 characters maximum.

Most all of the above was culled from faulty memory; all errors are mine. At the moment I don't even have a screenshot to attach to this message, though I'm almost certain I made a few of the slideshow side of GC-X in action when I was still using it.

I think this approach may be worth investigating.

(Update: before I wiped them to use for storage and an external Linux boot install, I did an extensive search of the pictures I'd saved on my two Mac hard disks. To my disappointment, there were no such screenshots. And a multi-page panning of Google Image Search a few weeks back turned up nothing either. Guess you're going to have to find a Mac and run the app to see what I'm talking about.)
