Inquiry about dpi images for VESTA

[abed haidar]

Good afternoon,

I was wondering how can we get high resolution figures from VESTA.

I know that from
File > Export raster image

But it does not high resolution image as much as I increase the export image option where if you look at the dpi it stay 96 as much as I increase dpi.

Any solution to that?

Thank you and looking forward to your reply.

Hi,

increase the scale factor (use 3 or more).

What is important is image size (in pixel). 

The DPI of your image depend on the size of printed image.

Thank you very much for the reply.
So vesta can not do that ? 

I have to do that from paint  is that correct?

Thank you Giorgio,

I tried your suggestion but yet the dpi is still 96.

My question to all for vesta are we able to increase dpi image in VESTA or not?

Thank you and looking forward to your reply.

Hi,

VESTA does not allow to set a specific DPI for images, bur DPI is a measure of the printed resolution .

So, take as an example the attached image, with a size of 5030x3750 pixel.

I have opened the image with a program (IrfaniView but you can use the program you prefer) and set DPI to 1200.

Your printed image will be 10.6 x 7.9 cm at 1200 DPI.

Best regards

Thank you all for the quick replies,

That is what I was asking for. So you chose a different software InfarniView and changed the DPI.

Then what is the meaning of Export raster image and you choose x =10?

What is the main difference between x=1 and 10

Thank you and looking forward to your reply.

the x=1 and x=10 are scaling the image.

it means if the image at X=1, if you want to zoom-in the resolution might distort more compared to the image at x=10 at same Zoom-in level.

so, in practical sense, the X=10 has more dpi (internally) to retain the resolution.

If I may suggest, why don't simply use the vectorial format? VESTA gives you the option to save the file in .ps or .svg for example which is resolution independent (this you can open later on inkscape or any other graphic software that handles vectorial formats and set the resolution as you wish). If you don't want to use the vector formats you could alternatively set the scale factor when saving your raster image on VESTA to a value larger than 1 (be careful not to make it too big so that you end up with a very large image size).

Cheers,

Lorraine

Thank you Lorriane,

-The problem as previously mentioned that with x =10 yes internally the image looks it has higher resolution but the dpi seems to stay 96.

-As for your vector insight, I tried to learn inkskape but I really struggled to work with it.

 

The only option is to make it x=10 and then copy the image onto powerpoint where I managed to export from ppt to jpg with dpi 300. Hopefully that works out.

 

Thank you all!

the x=10 image can be opened in Adobe photoshop or illustrator etc and then change resolution
