When I drag an image into Photoshop and go to "image size" I can see the size in cm (eg: 80X30 cm) In Windows 7, the only details you can see about the image regarding size is pixels and resolution. Is there a way in VBNET to get the image height and width in centimeters?
actually one Pixel = 0.264583 Millimeter.
There is a difference between Dots Per Inch (DPI) and Device-Independent Pixel(DIPs)
DPI and Device-Independent Pixels

im using image magick v7.16.0. i have a very big image of size 440*1700. i want this to be resized to 17% of the original Size.
I tried with Resize, Scale and Rescale methods with intended width/height parameters and also with MagicGeometry.
But the resized image wraps the pixels from left side to right side.Click here for the image
Can any one help me in understanding why this wrapping is seen ?
This wrapping is seen only when i resize to less than 25%. [ when i resize to 50% or 80% i dont see this wrapping ]
Having an issue with my images not being cropped using imageresizer. It crops fine on the height but does not crop the width.
here is an example: https://media.hillarys.co.uk/asset//media/10222/zen-collection-mishima-dawn-curtains.jpg?width=850&height=450&mode=Crop&quality=70
If I set the height to 400 it crops fine. However if I set the width to 300. It will resize the image.
This is really starting to get frustrating now. Any help?
Thanks
I see an image that is 850x450 pixels.
mode=crop (compared to mode=max or mode=pad) minimally crops to achieve the required aspect ratio, then scales the image down the the precise dimensions you requested.
If you don't want a minimal crop, then you should use crop=x1,y1,x2,y2. These can be expressed as percentages instead of coordinates with cropxunits=100&cropyunits=100.
I am using your resizer tool, it works very well, I am stuck at one place and need your suggestion to help me choose the correct image resizer settings
Everythings works fine when image is smaller than the browser window size I got problem when it's bigger than browser window
I am using the following parameters
orig.jpg?width=1600&height=530&mode=crop&scale=downsizeonly
for example consider a portrait image scenario given below
Browser window size = 1600 Width x 530 height
Original Image size = 1024 Width x 768 height
expected result: 1024 width x 530 height (so it should crop the remaining height)
actualt result: 1600 with x 530 height
Height and its cropping is ok but 1600 width is wrong I want it to be 1024 width so image didn't loose quality
Vise versa functionality I need for Landscape image
What parameter should I use?
The automatic cropping can cause upscaling even when &scale=down IF the requested dimensions would normally NOT cause upscaling with &mode=max or &mode=pad.
This is a known bug that will be fixed in a future release.
I let the user select a photo from the iPhone library, and I grab the UIImage.
I output the size of the image, and it says 320x480, but it doesn't seem to be, because when I draw the image on the screen using CGRectMake(0,0,320,480), it only shows the upper left portion of the image. Aren't the images much bigger than 320x480 because of the high resolution?
I'd like to scale the image to force it to be 320x480. If it is less than 320x480, it should not be rescaled at all. If the width is greater than 320 or the height is greater than 480, it should scale in a way so that it becomes as close to 320x480 as possible, but by keeping the proper proportion of width to height. So, for instance, if it scales to 320x420, that is fine, or 280x480.
How can I do this in Objective-C?
Setting the image view's content mode like this:
myView.contentMode = UIViewContentModeScaleAspectFit;
will preserve the aspect ratio.
While converting a webdesign given as a photoshop file to html+css, I got confused with font sizes. As seen on the image below, 30 px in photoshop does not equal 30 px in other Windows programs (different on Mac or others?), or browsers. This seems to be unaffected by creating the photoshop image in different resolutions than 72 which is default, and unaffected by change of units between pt and px. Can anyone hint on how to set photoshop to use browser px units?
The font size in the paint document refers to points, not pixels. Change the font size in photoshop to 30pt and they should be the same size.
A point is 1/72 of an inch and the pixel equivalent can depend on the DPI of your monitor. At 96 DPI 30pt * 1in/72pt * 96DPI (my screen res) is 40px. To convert pixels to points work backwards so 30px * 1in/96px * 72pt/1in = 22.5pt.
So change the paint text size to 22.5 and they should match up.
Set it to 96 dpi.
