Resizing Images Via Batch Process Has Problems

[mesmith322]

I frequently use a script to resize .jpgs from 3600x3600 to 1000x1000 dpi to save space on my hard drive. After resizing 300+ .jpgs last night, I found that they all retained their original file size. An image that started out as 3600x3600 dpi with a file size such as 3.5mb that was resized to 1000x1000 dpi using the script in X4 still had a file size of 3.5mb when it should have been considerably smaller than 1mb. I relaunched the application and rebooted my computer but no change. To fix the problem I had to run the .jpgs thru the batch process again using the same script but in X3.

The script I was using was created in X3 so I tried creating an identical script in X4. Regardless of which script I used in the X4 batch process, the same thing happened.

This problem seems to be unique to the script and/or batch process. I can open a .jpg file in X4, resize it from 3600x3600 to 1000x1000 dpi, save the changes, and the file size changes accordingly.

Can you post the script, or at least the Resize section?

Just such a script works for me, both in X3 and X4.

Attached is the script that was created in X3.

This was the script created in X4. They both had the same result when used in X4.

I have tried to reproduce what you find, without being able to do so.
I created a 3600x3600 Image, size about 3.5Mb
I ran a script like yours on it in X4 and then as a Batch Process and got the same result - 1000x1000 sized 400kb.

There are a few anomolies about your scripts:-

They will only work properly on square images. I use
'Height': 1080,
'Width': None,
with no AspectRatio setting

Your X3 Script has a strange Resolution: 9144 which looks wrong to me and just might be causing trouble.
There is a known bug where X4 assumes a Resolution of 72 when used in the Edit Mode.

All I did to create the scripts was "start" and then "save" recordings. I didn't edit any of the settings; they were just automatic. In fact, I didn't even know to look at the details of the scripts until I posted them in this thread. The resolution settings in both scripts stood out to me but I have no idea how they came to be. I was wondering how to get the script to work on non-square images using pixels instead of percentages. Since most of the time the images I need to resize in that manner are square, it hasn't been a big problem.

May I ask what type of processor you are using? I am having very similar problems with Re-sizing and Cropping under X4 when I did NOT have the problems under X3. I have an open case and there has been some discussion that it might be because I have an newer I7 Processor.

Sorry! I should have noticed that. Thanks for pointing it out.

[Kathy_9]

No problem - all boards are set up different and show info (or not) in different areas, so it's easy to overlook.

[mesmith322]

Kathy, have they found any answers for you yet?

[Kathy_9]

Sorry, but I wasn't really looking for any answers since I don't use batch processing. My only involvement in the thread was to help vciro, who was looking for your system specs that are listed under your avatar.

Since your script was an automatic recording created by the program and not something you hand coded, you might want to report it directly to Corel here https://www.surveymonkey.com/s/PSPX4

CAUTION!
I just downloaded and installed SP1 for X4 and I wish I had good news...but I don't.
Now, in addition to the Cropping/Resizing issue still being there, there is a new and much more serious issue. When I try to save ANY image as a JPEG, I get the same error message. It says that the file name is invalid. No matter what name I try, same message. If this save problem applies across the board to everyone, they really need to pull this back. Right now, X4 is basically not usable as is for me. Thankfully, I still have X3.

i'd never use psp for this. i use a program called easy thumbnail creator. http://www.fookes.com/ezthumbs/ which i can't fault.

@vciro - if i saw the filename invalid thing and i knew that it was valid i would assume it was trying to write something to an area of the disk it wasn't authorised to.

Hi Mesmith322.
I managed to get it working in X4 with the following procedure

1 Loaded large image. (even though in Irfanview it showed as 300 dpi, in X4 it showed as 72 dpi -- using the (I)nformation button )
2. Cropped to 3600 x 3600
3. Resized but unticked the resample box and changed the dpi to 300 . This does nit rezize the pixel dimensions which become greyed out. Clicked OK and then saved that.
4. Reloaded that image and this time X4 recognises it as 300 dpi as does Irfanview. (Strange what?? )
5 Prepared and recorded the script for resizing from 3600 to 1000 (don't forget to retick the resample box)
6. Did a batch process and all worked as expected.

I examined the script in wordpad and where in your X3 script it shows 9144 as resolution and X4 showed 72, mine now showed 300.
It may be that you may be able to edit that script and set that to 300 but I have not tested that.
