LV PDA 8.2 Need to install PNG support files if using Bitmaps?

[rberger]

Hello All:

I'm using 8-bit bitmaps in my LV PDA 8.2 Windows Mobile 5.0 app.  I found out bitmaps will not load unless I install the PNG support files into my PDA.  Is this a misnomer?  Should the PNG install files be called Image install files?

The reason why I post this:

I have an app where the user will have to install my app and supporting files, install the LV SMS files and now have to install PNG support files even though I use bitmaps only.  Well you get the idea, more installations means more chances of user errors.  Is there a package installer that can bundle all of these installations(i.e. Install Shield for Windows Mobile)?

BTW; My 3Meg bitmap that used to take 1 and a half in minute to load in v 8.01 now takes about 30 seconds.  This 3 fold increase makes my day.

Thanks

Robert

I am interested to know more about your application...
I am trying to work with greyscale bitmaps (8-bit) too and just make a DCT transform & add some bits. as to watermark it then back to IDCT to an image.

feel free to contact me at magedfawzy@hotmail.com

Robert,

You shouldn't have to load the PNG support files if you are just using bitmaps.  I just tried this on the Windows Mobile 5.0 emulator and it works fine with all types of bitmaps without the PNG support files.  I think this is a valid test because when I tried to use a PNG image on the emulator I got an error when it was trying to load lpngce.dll (PNG support file).  Is this the error that you get when trying to use a bitmap without the PNG support files?

Hi Justin 😧

You're right!  It does work without the PNG install.  I initially compiled my program on the PDA BETA v8.2 which gave me an error if I didn't load the PNG install.  I now loaded the released PDA v8.2 on that computer, compiled and ran.  Evertything works as expected.  Moral of the story, keep track of the release & beta versions and eleiminated all beta version from your computer(s) after release.

Thanks

Hi magedfawzy:

Not ignoring you just can't say anything until patents are filed.  You will know more soon though.

Thanks
