Where to blend?

  • Here's a quick alpha that i did on your image to show you how it should be done. Where the (deleted) alpha section is it will pull the default image below it to make it blend in much better.

  • After exporting to TIF, do we need the original BMP still it was created from?

    No. Just make sure that all other image files are changed to TIF to avoid issues. To be honest, i'm not sure if you can change only the image files that you edit to TIF and leave the others as BMP. I never tested that :)


    But, to answer your question, once you have the TIF, you can delete the original.

  • Hi,


    I tried several times mixed conversions of BMP and TIF. It worked all right.
    But of course you need TFW for all your files and have to remove the obsolete BMP.


    Nethertheless Jeff's advice can avoid unknown problems.
    See my USGS tutorial how to convert to TIF in an easy batch process.


    I did not try semitransparent alpha editing, because I'm not very familiar with gimp.

    I was happy I could describe the way with 100 percent alpha channel for the tutorial.

    But it is certainly worth a test.

  • You can apparently also blend by using multisources (1 BMP for picture, 1 BMP for mask) but I haven't totally figured out how it works in the GeoConvert tool...


    I also couldn't figure out what the TFW file is supposed to bring - I see strictly no difference when compiling with our without TFW file, the resulting AIC file is exactly the same afterwards and the compiled result also... Can anybody at IPACS please provide some detail about it?


    Cheers

  • The INF and TFW file support in GeoConvert is just for convenience here. GeoConvert needs to know what part of the world a certain aerial image is covering, the definition for this is in the AIC file. GeoConvert tries to convert INF and TFW files to AIC ( Aerial Image Configuration ) automatically, again just for convenience.


    The TMC file is completely different from this and is not linked to the AIC file at all.


    Using the TMC file you just specify the region where GeoConvert should generate aerial images and with what resolution.


    We will try to make this clear in the Wiki soon.

    Thank you so much for this much welcome information.

    This tends to confirms my understanding that once we have the AIC file(s), everything GeoConvert uses (and needs) is actually :

    - the source image file(s),

    - the corresponding AIC file(s)

    - and the tmc file.


    Is it right ?


    Can you please confirm that when I manually change something in an existing AIC file, it is taken into account and won't get overwritten when I relaunch the GeoConvert tool, whatever the INF/TFW files ?


    Thanks in advance

  • admin - can you let us know if geoconvert is happy with feathered edge transparency masks? I just went round the isle of Skye masking water with a soft feathered brush in the hope that the blend with base scenery would be smoother. Sadly geoconvert went wrong, bur i don't know if it was the feathering or something else.

    Hi Phil,

    I tried a slightly feathered mask in a small scenery test and it went through, but I definitely need to test if on water to try achieving a soft blending...

    Too many issues to fix first...
