Hello all,

I have been a long term Paint Shop Pro user due mostly to it's speed. Recently I have installed the demo version of CS4. However I have a problem with cropping.

How do I perform a 100% crop on an image, say 800x600 pixels out of a 15MP image?

I want it EXACTLY 800x600 with no resampling of the original.

In Paintshop Pro, I can type in the crop size I want e.g. 800x600 and the marquee will change in size to 800x600 pixels. When I crop, the crop is a 100% crop of the original image...i.e. no resampling.

With Photoshop, the 800x600 you specify is purely treated as an aspect ratio (or the final intended image size). When I crop, CS4 resamples the cropped section to 800x600, which to me is useless for 100% cropping but useful for other purposes.


Maybe I am expecting too much and the only way to perform a 100% crop is by dragging the marquee to the exact dimensions, but this method is pretty tedious, especially on a fully zoomed out image.
 
Go to Image

Then from the menu select Image Size

Then enter the height and width in pixels that you want in the top box

Sorry Chappers, but resizing the image resamples the image. I want to crop an 800x600 portion out of the image to produce an 800x600 pixel output picture.

or alternatively create a new document of 800x800, paste over the full size and drag to suit.

Ha, Ha...just tried that and CS4 crashed. Looks like I will stick to PSP for now.

Thanks for an answer though, although you lose the crop bars which is a downer.
 
If I understand you right, what you want is a crop an area which is exactly 800 x 600 on the full sized ( 100%) image.

There must be an easier way but the only way I can figure to do it is as follows.

Use the Marquee tool and set the dimensions you want in pixels. You do this by adding px after the dimenmsion. e.g. 800 px. Also ensure you have the style set fixed size.

Now select the area you want to crop. Once selected, right click and select Layer via copy. This copies the selection to a layer.

Now produce a new Photoshop document, at the size you want i.e. 800 x 600 pixels and drag the layer with the crop in to the new document.

Maybe an easier way but I can't find it at the moment. Maybe someone else can come up with a easier route.
 
What I do is in image size, ensure resample image is not selected and resize the original image to 72dpi, I then using the selection box select an area that I want to show and then click edit - copy.

Then go to File - New and set the box to 800 x 600 x72dpi and give it a name, then edit - paste and save, job done.
 
To do exactly what you are after, i.e. no resizing, copying to different layers, or any other faffing about :

Open your image in CS4
Select the marquee tool
In the toolbar along the top, under style, select Fixed Size
Two boxes will appear to allow you to enter your required width and height i.e. 800px and 600px
Click on your image and the marquee box will appear at exactly the right size
Position the box as appropriate
Go to Image>Crop in the menu
Et voila - One 100% crop at exactly the size you require

If you want to save this crop, do it as 'save as' and use a different file name, or you will overwrite the original full-size image.


The beauty of this method is that you don't need to be viewing your image at 100% for it to work. As you zoom in and out of the image, the marquee tool will change in proportion to the magnification you are viewing at, but will still measure the exact size you have entered.

Thanks for this.

The only downside of course is that you lose the crop borders which are quite handy.
 
If I have mis-understood apologies....Select the CROP tool, once selected type the required pixels and resolution in the CROP tool's bar that appears at the top. Crop around the whole of the image. Use save as as stated above.

Will say I am assuming that CS4 behaves the same as CS3 despite looking rather different.

At last !!!!!!

I did have a method which I used but it was really fiddly, this is great - You could do with putting this in tutorials, very handy

JUST TESTED AND ITS GREAT.

That gives you the ratio but not the actual pixels.
