Mirror multiple images

Topic

New Reply

For a PowerPoint presentation I have 90+ images that I have scanned from tranparencies with the slides back to front. I need to mirror them & I can do this one at a time in the image editor I use (Paint Shop Pro 7.04). Does anyone know if there is a way of doing this in a batch process without going to any significant expense?

You might try Quick ePics. It’s not free, but it has a30 day unlimited image trial period. $19.95 to buy. Never used it, but it should do what you want.

Doc Watson – Thank you for responding and for the pointer . I’ll certainly try Quick ePics.

Hi Malcolm

I know this is not an answer specifically for a way to reverse images in a graphics application but I have created a little bit of Powerpoint VB code that will allow you to do this without third party applications.

Insert the images that you want in you presentation then on each page:

Tools –> Macro—>Macros,

Select Reverse from the list and then Run.

This will flip your image horizontally. I have added a powerpoint presentation for you to use/copy as a demo…good luck

Jerry, I think he wants to mirror his images, not flip. I didn’t check your attachment – does it do mirror as well as flip?

Hi Al, maybe having a Saturday brain melt, but won’t a horizontal flip do the job?

MY brain melt, not yours. Doh! I guess I saw the word flip and not the horizontal. I instinctively think of flip as “upside down.” Sorry!

Thank you for your reply and attachment. I had great expectations but unfortunately when I run the macro it does no more than selecting the image & the text box. Nothing further happens.

As to your question I am listening in English!

Try this version. It is slightly more convenient – it loops through all slides in the presentation, you don’t have to select each in turn.

Sub Reverse()
Dim sld As Slide
Dim shp As Shape

For Each sld In ActivePresentation.Slides
For Each shp In sld.Shapes
shp.Flip msoFlipHorizontal
Next shp
Next sld
End Sub

Hans,

This is strange or I am doing something wrong as your macro doesn’t work either; nothing appears to happen! I opened the VB Editor & pasted in the code as i have done before but to no avail. I added two more slides to Jezza’s demo so that there would be more than one slide but nothing changed.

Have you tried to run the query (Tools | Macro | Macros…)? Have you made sure that macro security is not set to High (that would disable macros)

But DocWatson’s suggestion (Quick ePics) is probably more suitable for your purpose than a PowerPoint macro. Have you downloaded the evaluation version?

Reply | Quote

In PowerPoint the Security is set to Low. As the macros from Jerry & yourself work the problem I have can only be down to me.

Yes Quick wPics will mirror the images in the folder where I saved them after scanning. But the task is more than that as I now have to delete the incorrect image from each of 96 slides & insert the mirrored images. As in PowerPoint that tedious I was delighted at the bonus a macro could give me particularly yours.

I’ll have another look at using the macro later today.

Thank you for your help and courtesy.

How did you get the images into PowerPoint in the first place? If you used the Photo Album feature, this would explain why the macro doesn’t seem to do anything. The Photo Album assigns the images to be the background image of the slide, rather than inserting it as a Shape object. You might hunt around the PowerPoint and VB/VBA boards for macros to insert all images from a folder into a presentation and see whether that helps.

I am not aware of Photo Album.

To get the images into the presentation for each slide, one by one, from the menu I clicked Insert | Picture | From File. From the Insert Picture dialogue I selected the image for that slide from the store folder where the images had been saved after scanning.

Is this procedure why the macros will not work?

? Is this procedure why the macros will not work?

Pictures inserted the way you describe should be flipped by the macros posted by Jezza and by me. I don’t understand why it doesn’t work for you.

I am intrigued as to why the macros will not work. I’ll be like a dog with a bone until I find out!

If you wish, you can attach a small sample presentation with one or two slides. Zip it if necessary.

Thank you for your offer that I am glad to take up. Please see attachment.

I opened it on my work laptop and reset my macro security and after that it worked a treat. I think with this amount of effort it may be just quicker to do it manually

Reply | Quote

I agree wholeheartedly but the Rotate or Flip commands are greyed out with the image selected both at the Front and the Back.

There must be something in my PowerPoint set up that is causing these problems. In the circumstances I do not want to take up more of your time. Please accept my sincere thanks for your interest and assistance.

The macro in the presentation you attached works for me too (with macro security set to Medium). Are you sure that you have actually run the macro? It won’t run automatically. You must either select Tools | Macro | Macros…, select Reverse and click Run, or activate the Visual Basic Editor, click anywhere in the Reverse macro and press F5.
As Jezza notes, it may actually be quicker to process the images manually, using the Drawing toolbar (Draw | Rotate or Flip | Flip horizontally). After the first one, you can simply move to the next slide, select the picture and press Ctrl+Y to repeat the action.

I have Run the macros posted by yourself and Jezza. With Jezza’s macro the image is selected as the call in the first line of his macro. Nothing else happens. With your macro nothing appears to happen when it is Run. I can assure you that the instructions you give in your last message are what I have been doing with these macros.

To make matters worse when I go tp Draw | Rotate or Flip the list of commands is greyed out. This is so with the image selected or not selected. It makes sense to me that if these commands are not available this is why Jezza’s macro doesn’t flip the image.

I remeber an Irish foreman commiserating with me after several onsite minor disasters for which I was partly responsible `never mind son. There’s never one door closes but another one shuts!’

I think until whatever the problem is with my system until it is resolved this discussion is going nowhere. Please accept my thanks for your interest and contributions to this thread.

There definitely seems to be something wrong with your installation of PowerPoint. Have you tried Help | Detect and Repair from within PowerPoint?

I have PaintShop Pro 7 and went into it out of curiosity on this subject. I opened a file and then went to the Image option.

With respect the discussion has moved on from how to mirror an image in Paint Shop Pro. I am very familiar with how to do so. My original question was how to mirror multiple images (I have 96 of them) in a batch process, which so far as I know cannot be done in PSP 7.0. I have received very satisfactory suggestions for alternative ways of so doing for which, as always, I am duly grateful for the help & assistance I receive here.

As part of the discussion a macro was posted by Jezza to do the mirroring in PowerPoint and his macro did not work for me. Neither did the macro posted by HansV. Therefore me and them are trying to work out why those macros are not effective on my system. If you have any suggestion as to why this should be so I would be very pleased to receive it.

Oh that is disappointing as I thought I was onto something there.

It may be something to do with your macro security (clutching at straws here) try looking at Tools–> Macro—>Security and see what setting it is.

I had mine set to High and have now reset it to medium and it works…it may for you.

Your code does work for me, with macro security set to Medium.

As the macro Security setting in PowerPoint on my computer is Low the problem I am having with your macro must be down to me. I will look at it again later today.

AFTER you get the problem with fixing your images resolved, you might want to consider some other way to share your pictures, other than PowerPoint. I use this software and it’s pretty easy to use: LPJ-Software

Reply | Quote

Thank you for your suggestion. What I am doing is compiling a digitised version of the story of the apparitions that took place at Fatima in Portugal in 1917. With PowerPoint I can add a digitized version of the tape recorded narration that accompanies the slides. Is that possible with the LPJ Software?

Reply | Quote

Not sure what form your narration takes, i.e. MP3, WAV, etc. but the LPJ slideshow DOES allow the inclusion of audio with a show.

Not to be a wet blanket here, but you do have a basic problem in that you’ve scanned a bunch of slides “backwards” and regardless of your current PowerPoint situation, those JPGs (or whatever) DO need to be reversed somehow in their individual files or you will forever have this problem in future use of the pictures. It may eventually turn out that you DO have to do a one-at-a-time mirror in PSP, but whatever the mechanism, the individual files DO need to be fixed, for “posterity.”

Reply | Quote

The narration is a WAV file.

Yes I do appreciate that I may end up having to replace the wrong images manually one by one but with the magic of macros to use I think it isn’t a very elegant way of makng the changes.

Another software package you might use for this is IrfanView. This software is freeware and has many batch processes which can be applied to images. The advanced options in the batching dialog allow you to flip the image (along with many other options)

Reply | Quote

Sorry Andrew, but I’ve been looking at IrfanView (as well as other programs) and can’t find what you say is possible. Can you include a screenshot of the batch page that shows where one could “mirror” the images being processed, please?

Reply | Quote

Open IrfanView
Bring up the Batch function by pressing ‘B’
Then tick the Use Advanced Options tickbox
Click the ‘Set Advanced Options’ button
Flipping is listed under the Other Options area

Sorry about the big image – feel free to delete it once you have found the settings.

Thank you Andrew. The chore of flipping the images in Paint Shop Pro is not a major issue. My original question was out of curiosity in respect of the present problem & to be prepared if faced with the same situation in the future. Deleting the images from the presentation & replacing them is the real chore.

When in this thread I was presented with the `flipping’ macros I was delighted that it could be done so easily. But as the macros will not work for me – yet – I am intrigued as to why they will work for others & not for me.

Thanks much, Andrew. I don’t know how I missed that screen.

Well, just for the benefit of future Lounge searchers, let me add a contribution from fellow Lounger AlanMiller. BIMP is a graphics program I’ve heard of but have never tried (yet). It can be downloaded here: FileHungry Freeware – BIMP – Batch IMage Processor. So, now we know that there are at least a couple of freebies to do the job…
