Funny...

A 32 Bit Image is RGB image plus an alpha channel to define its transparency. CMYK( Cyan, Magenta, Yellow, Black ) is for printing... never ever convert a RGB image to CYMK. You will lose a lot of colors if you do.

:yes: hes right cdog is wrong ( i hope :p )

u got to change the mode from RGB to index then save then a box comes up and then select 32 bit u have a 32 bitmapped image :p :cool:

(if ur saving it as a .bmp)

:cool:

If you think photoshop is the be-all-end-all of graphics software then you have problems. That or you're a sheep.

Anywho, yes you're right and in fact, you can't save 32bit CMYK BMP images due to the colour loss if you did. It can't hold the colour seperation data. I do a lot of stuff for print so, forgive my mistake...but do me a favour and quit all this wrist action over photoshop...

I acknowledge the fact that photo-paint is a good software for image manipulation. But, i still think that photoshop is the best tool for this task. In fact nearly all the adobe products are the best in their own domains perhaps except indesign, which is not as good as the good ol' widely used Quark Xpress

Anyway, that's just my opinion :)

It does have to be a bmp. XP hardly even supports .png. Just look at the way it displays them in IE.

The alpha channel thing. If you add an alpha channel won't that force Photoshop to save in 32 bit mode? It should at least give you the option.

If you want transparency, then you'll need to give it an alpha channel. Bring up the layers toolbox and create a new layer, add whatever you want to the alpha channel then choose 32bit when saving.

Most programs however use the 'magic pink' colour to define transparency though.

in photoshop cs, i click save-as, select bmp, select where i want to save it, then it comes up with a window that gives me an option to save as 32-bit.

As a reference, that is exactly what Photoshop 7 gives you (talked about earlier in thread).

True enough.

If you give me a chance, I'll try exactly what you are trying to do later.

    • ChromeOS M137 goes stable, bringing new Face Control policy and more

      By David Uzondu · Posted

      ChromeOS M137 goes stable, bringing new Face Control policy and more by David Uzondu Google has brought ChromeOS M137 to the stable channel, and it includes a few focused updates for users and IT admins. A key change is a new policy for managing big groups of Chromebooks. The face control accessibility tool, which Google also updated back in ChromeOS M135, now gets a vital control for managers. A new policy called FaceGazeEnabled lets them switch the feature on or off across a whole school or company. The update also brings a new audio feature called crosstalk cancellation. It aims to create a better sound experience using just the Chromebook's built-in speakers. The software processes audio to make it seem like it is surrounding your head, not just coming from two small points. This tries to copy the feel of a surround sound system or good headphones. Any audio gets a boost, but you will notice it most when watching movies or playing games with directional sound. More accessibility tools have arrived, too. ChromeVox now has a direct keyboard shortcut, Search + O + C, that displays spoken text as braille captions on a connected display. For the poor souls in IT, troubleshooting got a little less painful as well. A new event-based log collection system, when enabled by an admin, will automatically upload relevant logs when something specific fails, like an OS crash or a botched update. Instead of digging through mountains of data, administrators get targeted reports sent straight to them. Here's how to enable it: Turn on the Device system log upload setting. Turn on OS update status reporting—For the Report device OS information setting, select OS update status. Turn on device telemetry reporting on crash information—For the Report device telemetry setting, select Crash information. Google also keeps things sane by limiting these targeted uploads to just twice a day per device. As usual, the update is rolling out slowly. If you do not see ChromeOS M137 for your machine yet, just be patient. This phased release lets Google find and address any issues before the update gets to everyone.
    • LG gram Book 15U50T: Is this lightweight laptop the right upgrade for you?

      LG gram Book 15U50T: Is this lightweight laptop the right upgrade for you? by Paul Hill If you’re in the UK looking for a new mid-range laptop that won’t feel underpowered, check out the LG gram Book 15U50T now because it’s at its all-time lowest price on Amazon UK thanks to a 14% discount from its £699.99 RRP. You can get it now for just £599.99 (Buying link at the end). At this price, the laptop definitely makes this mid-range option much more appealing, it’s also pretty new having only come out in January 2025, so you’re definitely getting more value for your money. The delivery is free and will take a few days to arrive unless you take advantage of a Prime member trial and get it next-day in time for Father’s Day. LG gram Book 15U50T: Key features and who it's for The LG gram Book 15U50T features a 15.6-inch Full-HD (1920x1080) anti-glare IPS display, making it ideal for use in well-lit areas as you won’t see yourself staring back. It’s powered by an Intel Core i5 processor (1334U), 16GB of RAM, and has a very fast 512GB NVMe Gen4 SSD. In my opinion, the storage might be a bit tight for some users; however, the device comes with two M.2 slots if you want to upgrade the storage. The LG gram Book 15U50T is ideal for students or professionals who need a device to carry with them out and about. It has an ultra-lightweight design and weighs just 1.65kg - that’s not too far off a similarly sized MacBook Air, but for a fraction of the cost. In terms of ports, there is an HDMI port, two USB-A ports, and two USB-C ports. There's also a 3.5mm headphone jack if you need to plug in headphones. Other noteworthy details about this laptop include that it's running Windows 11 Home with Copilot integration, it has a HD webcam with a privacy shutter, it uses Dolby Atmos audio for immersive sound, and it has a unique feature called gram Link for multi-device (including Android and iOS) connectivity. Should you buy it? If you are a student or a professional that won’t be doing heavy gaming, or using other super intensive applications, this laptop is a solid pick. It’s lightweight - so easy to carry around, it has an anti-reflective screen - so good in well-lit environments; and it features upgradeable storage slots if 512GB is not enough space. On the downside, this laptop has a mid-range processor that could limit your ability to use high-end professional tools. Another thing I’m not really a fan of here is how opaque LG has been with the battery life. As a portable laptop, you’re obviously going to want to take it on the go where you don’t have a charger handy, but all LG says about the battery is that it has a capacity of 51Wh. According to some online sources, variants of this laptop manage about 7 to 10 hours, so if you need a super long battery life, you might be better off with something like a MacBook Air. So should you buy it? If you’re not going to be doing anything super intensive, but can’t stand underpowered and slow budget laptops then this could be the ideal laptop for you. The £100 discount makes it even more appealing! LG gram Book 15U50T: £599.99 (Amazon UK) / RRP £699.99 This Amazon deal is U.K. specific, and not available in other regions unless specified.

    • Elon Musk once again claims Tesla robotaxis are coming soon

      By AnalystDan · Posted

      Totally different vehicles. Uber has partnered with Waymo for level 5 autonomous vehicles. Waymo has completed 10 million trips and to date, there have been 696 accidents in 4 years and of those 16 of them appear to have been due to an error by the car. In total airbags have only been deployed 38 times. The technology should always be under review and continued to be improved on, but this is a totally different animal to Tesla FSD PS. no I don't work for them etc. I am an analyst for a market intelligence firm and we have a lot of interest from clients looking at the connected car space for advertising etc. so I have studied them

      But it's not full self driving it's level 2 autonomy. Audi, BMW and Mercedes all have level 3 and make far less noise about it
    • Edge for Business gets secure password deployment for organizations

      By zikalify · Posted

      Edge for Business gets secure password deployment for organizations by Paul Hill Microsoft Edge for Business now offers organizations secure password deployments as a generally available feature, the Redmond giant said. Instead of users sharing passwords on sticky notes or via email to access certain websites or tools, admins can deploy encrypted shared passwords to specific users within their organization. When a user receives a password, it is stored in their Edge password manager and can be used to log into websites seamlessly using autofill. Microsoft has made this enterprise-grade solution available to customers at no additional cost. How it works and the user experience Administrators have to manage the feature via the Microsoft Edge management service within the Microsoft 365 admin center. From there, they can add, update, and revoke credentials for specific user groups through configuration policies. Once an admin has set it up and shared passwords with users, the users will see the passwords in their Edge password manager and can be used with autofill on corresponding websites. The passwords are tied to work profiles in Edge on managed Windows devices to limit their misuse. Further boosting security, the shared passwords cannot actually be viewed, edited, or deleted (unless the website allows), or exported from the password manager. This is a good addition for security because if an unauthorized user gains physical access to the computer, they cannot learn what the password is. Administrators reading this do need to be aware of an important caveat related to developer tools. A motivated user who wants to reveal the passwords can do so by digging into the developer tools, for this reason, you should consider restricting access to the developer tools by configuring the DeveloperToolsAvailability policy. The underlying security and encryption Microsoft’s new secure passwords feature has been built using the Information Protection SDK. The passwords are encrypted and the encryption is tied to Entra identities which lets organizations enforce them without manual key management. The decryption of the passwords takes place at runtime using the same SDK, validating the user’s identity. Availability and getting started Secure password deployment is available through the Edge management service in the Microsoft 365 admin center. Once in the admin center, you should choose an existing configuration policy or create a new one. Inside the policy, go to the Customization Settings tab and then to the Secure password deployment page. To use this feature you must have a Microsoft 365 Business Premium, E3, or E5 subscription. The feature also requires the Edge admin or Global admin role. Source: Microsoft
