I want change resolution of an Image.

I use the following code in visual studio with IEvolution

myimage.LoadImage(mysourcefile)
myimage.ChangeResolution(200, IEResampleFilter.Bicubic)
myimage.SaveImage(targetfile)

In Photshop the Resolution not changed but the pixelsize is reduced.

Where is my mistake?

Is there a new version 4.3.1 for remove only jpeg-header?
kclaas Posted - May 14 2013 : 00:08:41
I have another problem with IEvolution (Application crashs) and need an update to the uptodate version.

I have requested twice an update for IEvolution througth the downlod request form (http://www.imageen.com/support/downloadrequest.html ) to an uptodate version but I get no answer. The registration extension was orderd on 2012-08-14.

Can I download a new version anywhere?

Regards
Karsten

Next minor version will have a new method to remove only jpeg markers, without calling SetToDefaultValues().
kclaas Posted - Apr 02 2013 : 00:41:01
myimage.IOParams.SetToDefaultValues() remove all iptc-informations.
kclaas Posted - Mar 19 2013 : 12:52:43
If I use

myimage.IOParams.SetToDefaultValues();

I lost all my iptc-informations but I need the iptc-data.

It seems that CS3 stores DPI also inside other jpeg markers. Please try to set:

myimage.IOParams.SetToDefaultValues();
myimage.IOParams.DpiX = 200
..etc..

Unfortunately there isn't (as in ImageEn) a way to remove only jpeg markers. It will be possible in the next minor release (available soon).

I have send you the output.jpg
fab Posted - Mar 04 2013 : 14:17:40
Please could you send me your ""output.jpg" resulting file?
kclaas Posted - Mar 04 2013 : 01:25:11
In Windows are shown 200 dpi but not in Photoshop CS3.

I need after resave the correct resolution in Photoshop.


fab Posted - Mar 01 2013 : 00:48:58
What do you see in Windows property of the file?

I see the changed values:

kclaas Posted - Feb 27 2013 : 08:40:05
myimage.LoadImage("input.jpg")
Dim olddpi = myimage.DpiY
myimage.IOParams.XMP_Info = ""
myimage.IOParams.DpiX = 200
myimage.IOParams.EXIF_XResolution = 200
myimage.IOParams.DpiY = 200
myimage.IOParams.EXIF_YResolution = 200
myimage.SaveImage("output.jpg")

This code is not the solution, the result isn't changed! :-(
fab Posted - Feb 27 2013 : 02:33:45
This image contains also XMP tags (ImageEnVIew.IO.Params.XMP_Info), which contains "tiff:XResolution" and " tiff:YResolution" tags.
ImageEn doesn't touch XMP, unless you do it.
So you could write:

myimage.IOParams.XMP_Info = "";

However Windows properties on the file reports the right DPI (Windows doesn't read XMP tags).
kclaas Posted - Feb 26 2013 : 04:58:58
I sent an email with the image to support@hicomponents.com
kclaas Posted - Feb 22 2013 : 11:09:23
myimage.LoadImage("input.jpg")
myimage.IOParams.DpiX = 200
myimage.IOParams.EXIF_XResolution = 200
myimage.IOParams.DpiY = 200
myimage.IOParams.EXIF_YResolution = 200
myimage.SaveImage("output.jpg")

It doesn't work.

I use IEvolution 4.1.2.
I requested an upgrade twice on the downloadpage but I get no answer up today.

How can I send the input.jpg? It has more than 2 MB.

regards Karsten
fab Posted - Feb 22 2013 : 02:08:40
Please send a sample image, there are several places where to store DPI meta info (some unsupported by ImageEn).
You should try also:

myimage.IOParams.DpiX = 200
myimage.IOParams.EXIF_XResolution = 200;
myimage.IOParams.DpiY = 200
myimage.IOParams.EXIF_YResolution = 200;

Above operation is done automatically on latest IEvolution versions.
kclaas Posted - Feb 21 2013 : 07:50:29
Hi Fabrizio,

If I use this code

Dim myimage As New IEImage()
myimage.LoadImage("input.jpg")
myimage.IOParams.DpiX = 200
myimage.IOParams.DpiY = 200
myimage.SaveImage("output.jpg")

Nothing is changed in Photoshop.

fab Posted - Feb 16 2013 : 10:07:28
ChangeResolution changes also the image size. If you need just to change the meta DPI info, set:

myimage.IOParams.DpiX = 200;
myimage.IOParams.DpiY = 200;
myimage.SaveImage(filename);
kclaas Posted - Feb 14 2013 : 03:01:04
I want do that
