[gthumb-list] Flicker

[Iain Mellis <iainmellis googlemail com>]

Hi All,

tried sending this through earlier but it was deemed too large.

I'm looking for some help with a batch file. A friend of mine got this working in windows with gthumb, to flicker two images over each other. Would there be anyway to convert this to a sh or bash file and get it running with gthumb 3.4.0 in Ubuntu 15.10?

I use my own flicker script using imagemagick at the moment using 

animate -delay 50 -resize 600x600 %F %F.gif

but the images can't be aligned whilst the code below would do this.

Many thanks

CODE BELOW:

@echo off 

echo %time% 

SET steps=256 

SET comparison_size=200 

REM L ONH 700 

SET x_start=800 

REM L ONH 600 

SET y_start=256 

SET /a x_center=%x_start% 

SET /a y_center=%y_start% 

REM only need to make a single image for comparison 

convert %1 -type grayscale -contrast -contrast -crop %comparison_size%x%comparison_size%+%x_center%+%y_center% img_1.tif 

:next_step 

SET best_avg=0 

SET best_x=0 

SET best_y=0 

SET x_offset=-%steps% 

:loopx 

SET y_offset=-%steps% 

:loopy 

SET /a x_pos=%x_center%+%x_offset% 

SET /a y_pos=%y_center%+%y_offset% 

convert %2 -type grayscale -contrast -contrast -crop %comparison_size%x%comparison_size%+%x_pos%+%y_pos% img_2.tif 

compare img_1.tif img_2.tif -highlight-color Black -lowlight-color White -compose Src comparison.tif 

FOR /F "tokens=4 skip=1 delims=," %%i IN ('convert comparison.tif -scale 1x1 -depth 16 txt:-') DO SET this_avg=%%i 

IF %this_avg% LEQ %best_avg% GOTO not_best 

SET /a best_x=%x_offset% 

SET /a best_y=%y_offset% 

SET /a best_avg=%this_avg% 

:not_best 

SET /a y_offset=%y_offset%+%steps% 

IF %y_offset% LEQ %steps% goto loopy 

SET /a x_offset=%x_offset%+%steps% 

IF %x_offset% LEQ %steps% goto loopx 

SET /a x_center=%x_center%+%best_x% 

SET /a y_center=%y_center%+%best_y% 

echo %x_center%, %y_center% 

SET /a steps=%steps%/2 

IF %steps% GEQ 1 goto next_step 

SET /a x_displacement=%x_center%-%x_start% 

SET /a y_displacement=%y_center%-%y_start% 

echo Best Match found at X : %x_displacement%, Y : %y_displacement% 

echo %time% 

echo Beginning image preparation 

composite %1 trans.png circle.jpg first_image.png

I think that would be sensible. Many thanks for looking into this.

I was talking about the catalog order in the tree view, not about the
image list order, which  by the way can be changed from the actions
menus (the rightmost button on the headerbar).
