Re^2: resampling an image using GD not working on Linux

in thread resampling an image using GD not working on Linux

thanks stefbv for the feedback!

If I understand you added a print for field 1 and 2 of the current photo and you got a zero for the heigth?

This is probably a big design error from my part: I get width and heigth of the original pic from exif tags. Tags are read during the build list phase: i probably need to add a fall back method (using GD) to get anyway sizes if exif tags ones are not found.

If using the same photo you launch the program with the -debug flag you also view the current photo array dumped to the screen as received by the draw_photo sub.

In the following output the photo shows a width of 2560 and an heigth of 1920: you get a zero with your photo?

Considering files[0] C:\ulisse\img-renamer\2008_09_22_17_56_21_12.jpg
        photo data NOT defined for files[0]
        filled photo data for current: files[0]
HERE    draw_photo got:
------> C:\ulisse\path\photo.jpg|2560|1920|undef|undef|THUMB|PHOTO
        current 0 preload [1]
        filled files[1] photo data
        zero or other non significant increment for nex_pic
        OK loaded 2 photo data for files[0,1]

I added an issue to the github project.

While i still have many problems (no photos displayed) on Ubuntu I setup a Centos with perl 5.10 and GD 2.44 picwoodpecker runs quite well..

thanks again for your time and sorry for the late reply (here is big holiday weekend)!

If I understand you added a print for field 1 and 2 of the current photo and you got a zero for the heigth? Yes, that is what I did. Forgot to mention that my OS is Slackware64 and GD is v2.56. With the '-debug' flag, the output is: `Considering files[0] /home/.../picwoodpecker/2016_11_11_12_50_13_0.jpg photo data NOT defined for files[0] filled photo data for current: files[0] draw_photo got: /home/.../picwoodpecker/2016_11_11_12_50_13_0.jpg\|2272\|1704\|un +def\|undef\|THUMB\|PHOTO GD Warning: one parameter to a memory allocation multiplication is neg +ative or zero, failing operation gracefully` [download] Regards, Stefan	[reply] [d/l]
