I have been trying without success to enlarge and save schematic drawings in JPG or PDF format.

 

No matter what I do the enlarged JPG or PDF ,when I save it, is exactly the same as the original even though the file size has increased according to the "properties".

 

One of the file I am trying to enlarged is attached.

 

I need a much enlarged image to be able to print out, as printed in the current size make the schematics extremely hard to read.

 

I know how to enlarge the pic in "Paint" but the enlarged size will not save.

 

I would be grateful for any suggestions which may help me with this issue.

Followed your instructions to the letter and the end result was the same.

Saved file is the same as the original.

Enlarged it in Paint to 160% and looked great on screen but when I saved it was the same small size as the original.

 

Have I missed some available setting in 'Save as" mode??????

 

Tried opening the saved file in Photo Viewer and Photoshop but made no difference.

 

Exactly the same thing happens if I use the On Line enlarging services

You don't have to do what Havachat did, he's already done it for you. Just print the file he's provided, it fills an A4 landscape page.

I Dunno ?

 

This Works Also:

 

1/ If they are PDFs as you posted first time , { the one i worked with } , then it should work if you open with Adobe { I use Sumatra } enlarge to your Pc Screen , and then     Hit -  the Key on Keyboard "PRT SC". { What you see on your Screen is what it will Capture }.

2/ Open Paint and select " Paste".

3/ You Can use the "Crop"  feature in Paint , but leave room around Image.

4/ Then Click " File " Top Left  and " Save As " and select JPEG.

5/ Open with Windows  " Photo Viewer "   and Click " Print "

6/ You may have to Uncheck - " Fit Picture To Frame " { I did to have full Image }.

 

 

If you Have JPEG Images , that would be the same -

 

1/ Just open in "Paint" and Zoom In and then Hit the "Prt Sc" { Now its on the Clip Board }.

2/ Close Paint.

3/ Reopen Paint and then Hit "PASTE"

4/ And then Save as JPEG { Select a Folder } eg: Downloads.

5/ Open the File { Image Viewer } and Select Print.

6/ This should work.

Ah, OK.

Are all the images available as PDFs?

If the purpose of the exercise is to print at a desired size, you should already be able to print at whatever size you wish. In the Adobe PDF Reader, on the Edit menu choose Take a Snapshot, highlight just the schematic. OK the confirmation dialog, go to File...Print, choose the Size and Orientation, Print.
