Changing Pixel Colours

Hi,
Is there a way of changing pixel colours in (say) a Graphics (or image) object? I want to be able to create a Graphics object, and then change pixel colours, as determined by the results of a numerical simulation, as results are generated.
Any help appreciated!

You can use the drawLine to draw a one-pixel line in the right place.
Alternatively (and probably better) use an int array to contain your image data and use a MemoryImageSource to generate an Image for display from that.

[SOLVED] Rapidly changing pixels in X (Intel 945GME)

Hi,
A few days ago I managed to install Arch Linux on my EEE Box B202 (thanks, devs), containing an Intel 945GME chipset. Everything looks fine, but when I start X, the screen goes black for a few moments (monitor complains 'no sync') and when it is back on, I sometimes notice some screen glitches: a few times a minute there is a little flicker somewhere (especially when something on the screen changes) and pictures are not 'steady', i.e. there are pixels that rapidly change colour (e.g., in the Google logo). On smooth surfaces I don't notice those glitches (or they are less noticeable).
My monitor is connected using a DVI-cable (so, without the DVI-to-VGA-adaptor). In WinXP there are no glitches, so it couldn't be due to the cable or the 945GME chipset that can't handle this resolution... I tried using xf86-video-intel 2.4.3-1 and libdrm 2.3.1-2 as well as xf86-video-intel-newest 2.6.1-2 and libdrm-newest 2.4.4-2 from AUR. On another box (with a i82915G/GV/910GL graphics chip) there are no problems with these drivers (well, connecting using the VGA-port, that is).
I already searched the forums for this (also the Ubuntu- and EEE-users forum), but nothing helps. My xorg.conf reads

When adding @60 to the Mode "1280x1024", my monitor complains about the signal being out of range (despite displaying a somewhat unsharp picture). Uncommenting the "NoAccel" option and commenting out "DRI" didn't solve this problem (only slows down graphics drawing a lot).

Sorry for bumping this old topic, but I managed to workaround this problem (still the same hardware).
The last year I used xf86-video-vesa, as the mentioned problem didn't show up using this driver (and screen rendering in X wasn't slow, so I was fine with that). After getting disturbed by some random screen flickering after KMS was enabled by default (while still adding video=791 and using xf86-video-vesa), I decided to try xf86-video-intel again combined with KMS.
After fixing the above misconfigurations I rebooted and my screen was dropped in a console using 1280x1024@75Hz. Using several consoles for a few hours worked flawlessly. But when starting X (with an xorg.conf generated via X -configure and disabling input hotplugging) things got worse.
At first, I didn't notice anything using black-on-white xterms. But after running Chromium I saw these flickering pixels again, a horizontal line (the bottom of the back button) showed pixels that changed colors rapidly. The problem appeared to be dependent on the contents of the screen: dark, patterned surfaces like several of these pictures acquired a lot of green pixels moving fast (I hope this is comprehensible), the "Floating Diamond" also got some rapidly changing pixels. Moreover, I got a small black line flashing every now and then.
I thought that the refresh rate might be too high for the Intel GPU to cope with (the monitor should be able to handle this). After way too much searching, I discovered how to set a refresh rate in KMS: I added
kernel /vmlinuz26 root=[...] ro video=1280x1024@60
^^^^^^^^^^^^^^^^^^
to /boot/grub/menu.lst.
After a reboot the refresh rate indeed dropped to 60 Hz. X stubbornly refused to stick to this (I thought it merely used the graphical mode KMS set). A bit more googling resulted in the following adjustments to xorg.conf:
Section "Monitor"
Identifier "Neovo F-419"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 31.5-64.3
VertRefresh 50-70
EndSection
Section "Device"
Identifier "Card0"
Driver "intel"
Option "monitor-DVI1" "Neovo F-419"
VendorName "Intel Corporation"
BoardName "Mobile 945GME Express Integrated Graphics Controller"
BusID "PCI:0:2:0"
EndSection
Now my X runs at 60 Hz and... the rapidly changing pixels seem to be gone (for half an hour at the moment).
Only question that remains is: why didn't I have these glitches outside of X? Is it because text screens have relatively large areas with the same color? After all, this 'noise' was best visible on heavily patterned areas.
And one last question: should I mention this somewhere upstream (e.g. at the xf86-video-intel people or at LKML)?

How to get pixel colour?

Is there any way to get pixel colour from specified point? Example: colour = image.getPixel(x, y);
J2ME/MIDP 1.0
Thanks!

{color:#800000}*I am happy to compare the two pixels of same image using this code in Java:*

int pxl[]= new int [65536];
PixelGrabber pg = new PixelGrabber(ori,0,0,256,256,pxl,0,256);
// Image is stored into Array
try{ pg.grabPixels(); }
catch(InterruptedException e) {}
for(int i=0;i<65536;i++)
{ int p = pxl[i];
int ri = (0xff & (p>>16));
int gi = (0xff & (p>>8));
int bi = (0xff & p); // Take the RGB value of each pixel
for(int j=0;j<255;j++) // Chk. other similar pixel in color range of 0 to 255
int q = pxl[j];
int rj = (0xff & (q>>16));
int gj = (0xff & (q>>8));
int bj = (0xff & q);
if ( (ri==rj)&&(gi==gj)&&(bi==bj)&&(!(i==j)))
{ ri+=70;//if (ri<0) ri = 0;
gi+=70;//if (gi<0) gi = 0;
bi+=70;//if (bi<0) bi = 0;
pxl[i] = ( 0xff000000|ri<<16|gi<<8|bi); // Change value
else
pxl[i] = ( 0xff000000|ri<<16|gi<<8|bi);// Keep as it is

Pixelated coloured fonts ...

I put a blue text layer (the name of the shown person)
on top of a clip, but unfortunately the text is blurred and pixelated
at the edge.
I built it in FCP and in BORIS.
If I change the colour to black or white, the edges are fine!
Does anyone have an idea, how the get a sharp edge on a blue text?

Sorry, wrong forum!

Change the colour of events in iCal

I need to change the colour of events/appointments in the Mac iCal. I have imported all of my Outlook calendar via google sync and all my appointments are now just one colour. I have my medical appointments coloured in orange so they stand out each week (I have many) and all my personal events a different colour, and my volunteer work a different colour so that I can see at a glance in week view what I am up to. Looking at one week with every appointment in one drab colour is not nice.
I notice that different calendars are different colours, but I dont want separate calendars as I need to sync with google to share the calendar with Android phone and iPad.
Please can you let me know how to turn this feature on. Many thanks.

Click calendars at the bottom of the page the click on the i symbol for info and then you can select the colour you'd like.

Change the colour of the outer line of a circle

Hello everyone,
I drew up a circle with no fill inside, to show where the location of my highway storm culvert will be.
I changed the thickness of the outer line of my circle shape by creating a stroke effect at layer → blending options → stroke; then I changed the thickness of the line by right clicking in stroke at the layers panel and then choosing "scale effect."
But the problem I have is that the outer line is gray, and I want it to be black.
The outer line was originally red though so I changed my image → mode to grayscale, because I couldn't find a way to change the colour while keeping my image in RGB colour. So I've managed to make the outer line gray by changing the image mode but I still can't change the colour of the outer line to black.
I'm sure there must be other ways of changing the outer line colour without having to change the image mode, but I'm clueless.
Here is my drawing:
The text next to the circle says «Obra de desagüe». That's spanish for "drainage construction site."
You see, I can't change the colour because I have no clue at where the "change colour option" is. I tried going to layer → layer properties, but in there there's only 7 colours to choose from. I chose a random colour, just to see what happens and what truly changed colour was the layer, within the layers panel; not the shape contained within the layer.
So I'm lost here, any help please?
Unfortunately I'm still not an expert in Photoshop just yet.
Thank you for reading my post.

Set shape layer opacity 100% Fill 0% to make fill transparent or add an empty layer make a circular selection stroke it black.

Best way to draw an asset if I want to change the colour of it?

If I draw something manually, can I still change the colour by actionscript?
I want to draw a cat, and the cat colour depends on the the user choice in the previous 'screen'. How should I go about this?
Thanks.

Yes, there are a couple ways. You can use the ColorTransform class. Or you can use one of the Tweening engines - it's really easy to tint objects using TweenLite. You can even test in the demo at http://blog.greensock.com/tweenlite/
Scroll down a bit to the demo... pick a color in the tint box and hit Tween.

How to make this image compatible as a laser cut file by changing stroke colour?

My final aim with this image is to make it compatible as a laser cut raster engrave design, so the laser cutter will fill the black areas or white (either would be fine). If this is not possible then even as a laser cut outline would be suitable
This is how the image will look when in Illustrator. however when I use the preview screen (ctrl+y) it creates an outline. This is how the laser cutter will read the image which is why it is very important the preview image is is what i would expect the final outcome to be.
As a raster the laser cutter requires the stroke line to be blue r:0 g:0 B:255. Currently I cannot edit the colour, yet I can change the stroke weight. Also how I would I fill the engraved areas as a stroke? At the moment when I try converting the stroke to blue it turns grey.
I am also unsure as to how I would make this feasible even to be cut out when I cannot change the stroke colour to red. This is required for laser cut designs as the laser cutter reads red lines to be cut.
I can usually change stroke colours easily so I assume this is due to the fact that I have brought this file through from Photoshop so it is not yet fullu editable. I have used the live trace and live paint function in illustrator so far.
Any help would be appreciated

You need to expand the artwork and convert the strokes to genuine outlines to in turn be able to apply anotehr thin stroke to them again...

How do I stop B/W photos changing to colour?

I am running LR 2.7 on a Mac and this weekend for the first time, I set my camera to black & white mode and took a series of raw photos. When I imported them they all came across in the filmstrip as black & white but as soon as I started viewing them they changed to colour. I know the raw file contains all the colour data etc. but I really wanted to work on the black & white image from the camera and not have to start from a colour image? What did I do wrong? How can I stop it changing in future when I shoot raw files?

Lightroom knows little to nothing about your in-camera process settings. So, setting the camera to B&W and expecting the images to be correctly rendered is futile. The following post from the FAQ forum should help explain the reasons http://forums.adobe.com/thread/358016?tstart=0
If you really want your images to appear as B&W in Lightroom you can apply one of the B&W develop presets during import.

How can i change the colour of the keys on my mac? is it possible to get them changed?

i was looking at a macbook i was today and it's keys on the keyboard were in a rainbow formation, with different colours. Is there a way to bring mine in to change the colours of the keys? or did i have to order it like that?

Hi,
What do you mean by travel? Is that when it wont change all settings across the board? e.g another staff member with adobe acrobat wont have the same settings as i do?
I am the only one creating the forms and using any adobe settings anyway so i guess it wont really matter that they dont have the same settings as i do but its not hard to change them on all pc's anyway.
Thanks though.

Is it possible to change the colour of the bars in a chart on the iPad?

I'm using keynote for iOS and I'm trying to pick the bar colour for my charts. I understand that the default settings will change the colour for each new series but I have a few charts all with a single series and I would like to change the colours along the way. Below is an image from my presentation, basically I'm looking for guidance on how to make the blue bars into red bars.

Set the grid background color black and set the GridItem background color something else.
Here is an example.it is better to set this kind style attributes in css

    <mx:GridItem backgroundColor="#FFFFFF">
     <mx:Label text="Testt"/>

Newby question. Trying to fill a section but using fill and/or stroke only changes line colour

Hi,
Been trying to work this out for hours now so if anyone can help I will be forever thankful!
Basically, I traced an image earlier, expanded it then wanted to change the line colour. For some reason I couldn't get this to work even though I've done it in the past. So, I used the magic wand to select the line then dragged it into my new document and changed the line colour.
Now, I want to change the fill on certain sections, however when I change the stroke it changes the colour of the line and when I change the fill it changes the colour of the line.
I'm not sure if that makes sense or if anyone can help based on that but I can post pictures or something if that would help?
I also understand that the magic want thing might be where I've went wrong at the very start maybe?
Thanks for any help at all!

I don't know if that helps you understand at all?
For example I want to fill the inside of the square but when I'm hitting the fill and stroke buttons they're just changing the colour of the line.
I think I might just start from scratch again! Don't know where I've went wrong.

Just uploaded iso7 , . . .hate it! Can you change background colours? How do you add a new item/activity to the schedule? In notes the font has changed, can I change it back and the link colour is now yellow instead of blue, can I change it? Thanks

Another question. How do you bookmark something. It was so easy before, why did they change it? Can I uninstall it?

In ios7 is there a way to change the colour of a sent text?

Since upgrading to ios7 & on my iphone 5 the sent text messages in a conversation (my messages) are white on green and I don't find it that easy to read when I want to look back over a conversation. I tried making it bold in the Accessibility area of settings but that it no better. Inverting colours gives me a horrible purple. \does any one know if there is anyway I can make the text other than white - black on green would be fine.

Hello again, Helen,
While this doesn't actually change the colour of the mouse pointer, Mouse Locator does make it very easy to spot, even on a large display.
And it's freeware into the bargain!
