Color space: RGB 32 Bit.

[Leo11221]

I need to save a .jpg in a certain format which is

- Resolution: 72 dpi
- Color space: RGB 32 Bit.

Just wondering how I would go about this? cheers!

I am not sure with PSP, but for specific things like that are fit specific apps - like Gimp or http://www.qualibyte.com/pixelformer/

RGB isn't actually all that specific. It's like being asked what make and model of car you have and you say it's a sedan. That being said, sRGB is by and large the default work space both for PSP and most of the rest of society. I'm assuming that you need sRGB, but you should double check and make sure it's not something else.

So, unless you've changed something in PSP you're already working in sRGB. Click File> Color Management> Color Working Space. You'll get a dialog that will allow you to choose from profiles that are installed on your operating system. If you don't have the profile for the space you need you'll need to download it. Google the ICC Profile for the RGB color space you need and pick the safest looking link, follow the directions.

As for saving at 72 DPI that's also a bit misleading. If you don't specify a particular print size the number is just a number. If someone is asking you for it though many times it's just easier to comply than to argue with them. Click Image> Resize and you'll get a dialog box appear that will get you the rest of the way. Resolution is what you'll want to change to 72 DPI. Click Advanced Settings and make sure that Lock Aspect Ratio is still checked. Also resize all layers. Resample Using: could also be set to Smart Size, as that's the setting that lets the program decide what type of algorithm to use for what you're doing. If you aren't changing the pixel count any it won't make much of a difference though.

Using PSP X3 or X4, you can change the resolution of your image to 72 dpi via the IMAGE > RESIZE.

The only problem is the "Color space: RGB 32 Bit" since you can only increase the color depth of an image up to 16 bit/channel via IMAGE menu > INCREASE COLOR DEPTH and not 32 bitm this will show up as a 32 million color image ... but only 16 bits.

Ok so is it possible to make it 32bit using other software? its a picture for a website and they were very specific about the image requirements.

You may want to find someone who can take care of this for you to do your web design. This is a pretty basic function that a lot of people tend to overcomplicate and confuse. The short answer here is in PSP click Image> Increase Color Depth> RGB 8 bits per channel. If this is grayed out, then it's already at least 8 bit. if 16 bits is grayed out you'll need to DECREASE the color depth. What PSP calls 8 bit is actually what you want. Then resize the image to the dimensions that you want (Image> Resize) at the dpi that you need (72 dpi).

Most images are already "32 bit" unless you're talking about computer generated graphics. The confusion comes into whether you're refering to the image as a whole or if you're referring to each individual channel. RGB stands for Red, Green, Blue. Following what I wrote above would give you 8 bits per channel, add all 3 channels together and you get 32 bits. If you add an alpha channel or an IR channel you start getting even more, but that's getting off topic. PSP's 8 bit (as well as Photoshop and everyone else) is also known as 32 bit. Unless you don't have an RGB file, and it's a graphic of some sort, then you're likely already right where you need to be.

72 dpi is one of those things that's just unnecessary to set. See http://www.rideau-info.com/photos/mythdpi.html You'll need to know the size more than the DPI. All web browsers will rescale the image to 72 DPI. You can rescale all day long and if you don't change the pixel count you're not changing anything. If you're working with a pro, either point them to the link I just provided or if that doesn't work find a pro that actually knows something about what they're talking about.

Technically, Df, RGB is 24-bit. RGBA is 32-bit.

You're right, didn't add correctly.

Why would a web developer need an image with an alpha channel? Seems odd to me.
Again, if you have a jpeg from a camera and want to display/add it to a website and you're working with a pro web developer then they should be able to convert whatever image you give them to work. If they can't then they have no business calling themselves a pro.

PNG transparency is used quite often over GIF these days because of the better quality and higher bandwidth.
