I want to know how to resize a photo without loosing quality....... in the image resize box the is a check box that says maintain file size ......what does that do .
I have tried to resize using it and the file stays the same as the original.
Thanks for any advice
Mike

Ir should be changed to say maintain pixel count as that is what it does.
With Photo-PAINT you can change pixel count or you can maintain resolution and change physical size or you can change physical size and resolution.
If the unit of measurement is pixels and you want to change pixel coount just change them. but unchek the maintian image size
If you have the maintian box checked you can if using a measure other than pixels change physical size and the resolution goes up or down.
With a unit of measurement other than pixels you can change physical size and maintain resolution by unchecking the maintain image size.
I think there is something wrong to be honest ......I do the same thing in photoshop and it stays at 300dpi when i reopen it .........in corel it goes back to 72dpi.....even if I save it as a new doc....... somethings not right ......
Is there any tutorials on photo resample as i think its so complex with diff types of measurements and dpi.......... I'm confused.
Thanks for your replys
I've seen discussions about something like this for several versions of Draw/Photo-Paint.
I suspect there is a conflict between the DPI as stored in the file itself and DPI as stored in the EXIF meta-data. The short description is.... resample in Photo-paint & save. Other apps show the correct dpi (like photoshop or irfanview) as stored in the file itself. But photo-paint seems to read the exif dpi instead when you re-open it.
Anyway, that's my suspicion.
Frustrating.
Yes Harry its a 24bit Jpeg...... but heres the strange thing if I save it in CPT its keeps the 300dpi when I open it ....... also when I save it out after opening it in CPT it comes back 300dpi........so it wont open in jpeg change to 300dpi and save like that .....I have to save it in cpt reopen and then save in jpeg......... odd!
Oh and yes Harry I got all updates.
What was the source of the original JPG file? Some cameras and some older versions of PS had JPG issues that were picked up by PP.
BYW if you save as any other format and then as JPG it will work.
JPEG Files can contain EXIF data. This data may affect how the files open.
i.e. if the file EXIF information contained in file then file is opened in its original size/resolution
One way is to open file (with EXIF information, e.g. photo from camera) copy layer into new file and then resample and save (no EXIF information in file) and file will reopen in new size/resolution (tested on XP SP2, CDGS X5 SP2)

David the source was a canon D5..... .The trouble with saving it to another file is what about if i want to do a batch of them .... i normally copie from CF card to comp then make copies to a new folder then do a batch to a smaller size but still want the quality .
mike Rawlinson said:David the source was a canon D5.....
Ok not to be critical but to make sure you understand the facts. A first generation JPG file resaved again as a JPG file loses quality. I get them all the time if I want a batch I save them to CPT and resize to JPG keeping all my archived files onthe server as CPT files.
JPG compression is lossy!
So when I off load from my camera it comes in as a jpg...... then I should save to CPT ?...... But if its already a jpg the quality will not be as good as say TIFF......... can i save from the camera to TIFF ?.......maybe i should shoot everything in RAW.....is that an option ?
Now I'm really confused to be honest .....
David let me get this right .....your saying if I save first generation to CPT it will be the best I will get ....
Foster I'm not sure what you mean .
Why would a canon D5 generate such a poor format photo ...... or am I way off the mark.
BTW i'm only thinking of photos going to print NOT web .
Thanks for all the info......... not sure I understand some of it but it all helps me make a choice.
