PE 2023 dims "Sharpen" menu item for my opened GIF. 

Please explain

[Jeff Arola]

Gifs are in Indexed Color Mode for which photoshop elements has limited editing options available.

Go to Image>Mode and click RGB Color

May I ask another question?

I have a great smoothed image, almost 100% UN-pixelated. 

So, I go to Elements and use resize to make it smaller. 

Image becomes severely pixelated and unusable. 

What am I doing wrong?

[Jeff Arola]

Make sure your viewing the resizes image at 100% view (actual pixels)

(double click on the Zoom Tool or go to View>Actual Pixels)

If you try to xoom in to make the resized image fit the screen and that's larger than 100% view, then the image will be pixelated.

Jeff,

Your patience with me is beyond awesome ... can you stand another follow-up =

It's obvious that the following has nothing to do with Photoshop Elements, but you or some of the folk with whom you work just may be programmers and have a hint or hints.

You may have guessed already that my "forest" is my writing a Javascript Game with, of course, <canvas> and HTML5.

I have a beautiful HD-quality image which I need to down-size .. and as you have stated, that results in producing jagged edges.

Unfortunately, <canvas> does not permit scaling of the image via the predominantly used .css code wherein width and height of the image is expressed as a %.

If it were that easy, I assure you I would not be bugging you.

<canvas> as a substitute uses its native drawImage call buried in the <canvas> API, e.g.

canvas = document.getElementById(boardID);

ctxBoard = canvas.getContext("2d");

followed by:

ctxBoard.drawImage(myBall, ballX, ballY, ballWidth, ballHeight);

Anyway, the above 2 images show the "before" and "after"

A major reason the HD image is so big is that this large size was necessary to generte its high resolution.

In photoshop elements are you using Image>Resize>Image Size?

Can you provide a screenshot of the settings?

Jeff,

I am no longer trying to alter the size of my HD image within Elements.

My review of various JavaScript programming sites shows that a predominant % of these programmers claim that any alteration of the image size by any external graphics program will always add pixelation when the Browser window is resized. 

I have shown that on my own with Elements. As long as I don't mess with my original HD image, pixelation = zero.

Change it's size with any option such as bicubic and pixelation happens. 

They continue to state that the only way to resize a HD image is via Canvas via JavaScript. 

And that is what I am currently exploring.

I'd love to upload to you 1 or 2 of my HD images - but I don't know how.

BTW the "before" image above is my original HD image. 

If I resize it with Elements, any change of the Browser window size, "after" occurs

HORRAY

I accidentally discovered how to retain my HD-quality images with resizing. All I had to do was specify a in-line style for my <canvas>:

<canvas id="gameBoard" width="1024px" height="1024px">

lots of HD images here

</canvas>

Haven’t uploaded to Server yet … but that’s next.

I went around-and-around with about 15 javascript code functions, none of which worked. 4+ days and all I had to do was change one stinking line in my .html file.

My younger son has a 82-inch wall mounted iPad-like screen at work.

YUMMY!

[John26549578o2bk]

Maybe this is adding unnecessary Carbon to the air ... but it definitely is he right thing to say.

I can never thank you Jeff Arola. Even though I solved the roblem with a very simple change of ONE line in my <canvas> division in the .html file, your patience is outstanding and without blemish.
