How to do really simple things? tool change, set color etc.

Hi all

I tried to do a color picker. I managed to make it work with a user interface and all the sweet looks, but I have no idea how to actually do something! Photoshop, he's throwing very well.

Really simple things:

1. How do you define the pipette tool? (I already have working code that detects when the mouse moves outside the window)

2. How do you define the color? Looking as setColor() function so that the current color, and the user can preview the result (i.e. color overlay)

For me, seems like these two would be a simple of liners, but I can not for the love of God understand how do!

However, documentation for JS is pretty good, but I was not able to run my swatches JS code. Here's my attempt att runs javascript code:

bool runJavascript (const char * jscode)

{

Validation test

If (sSPBasic is nil)

{

NSLog (@"sSPBasic is NULL");

Returns false;

}

ASErr err = 0;

JSScriptingSuite2 * sScriptingSuite = NULL;

ERR = sSPBasic-> AcquireSuite (kJSScriptingSuite, kJSScriptingSuiteVersion2, (const void *) & sScriptingSuite);

If (sScriptingSuite == NULL) //Also support Photoshop CS4 CS1 and items 6-10

ERR = sSPBasic-> AcquireSuite (kJSScriptingSuite, kJSScriptingSuiteVersion1, (const void *) & sScriptingSuite);

If (sScriptingSuite == NULL) return false;

JSEngineRef engineRef = NULL;

ERR = sScriptingSuite-> CreateEngine (& engineRef);

If (err is kSPNoError)

{

Ascii to unicode conversion

wchar_t * wcode;

size_t codelength is strlen (jscode) + 1;.

wCode = (wchar_t *) malloc (codelength * sizeof (wchar_t));

mbstowcs (wcode, jscode, codelength);

const ASUnicode * result = NULL;

ERR = sScriptingSuite-> ExecuteScript (engineRef, (ASUnicode *) wcode, kJSExecutionModeNoDebug, & result);

If (err! = kSPNoError)

{

NSLog (@"error (%d) JavaScript.) ("Script: %s ', (int) * result, jscode);

}

on the other

{

NSLog (@"JavaScript OK!");

}

Free (wCode);

}

on the other

{

Returns false;

}

If (engineRef)

{

sScriptingSuite-> DeleteEngine (engineRef);

}

Returns true;

}

Which doesn't really work. It seems that the culprit is the conversion of char * in ASUnicode. In the example they had

const ASUnicode test [] = {'a', 'l', 'e', 'r', 't', ' (','------", 'h', 'i', ' \", ' ') ' ', ', ';', 0};

which works very well. But apparently I don't convert my string to ASUnicode the correct way. Ideas or comments are much appreciated!

CBC char [1024] = "alert ('Hello dissolve')";
ASZString newZString;
ASUnicode script [1024];
sASZString-> MakeFromCString (src, strlen (src) + 1, & newZString);
sASZString-> AsUnicodeCString (newZString, script, strlen (src) + 1, false);
const ASUnicode * result;
sScripting-> ExecuteScript (engineRef, script, kJSExecutionModeNoDebug, & result);
sScripting-> DeleteEngine (engineRef);
sASZString-> Release (newZString);

  • How to automatatically answer the question of "change the color space?

    After obtaining of CS4 I will often wonder if I want to change the settings of the color space of the image I want to open.

    In previous editions of SP/c, you can access the General settings and set the response to be automatically always the same (always ask/never ask/always the existing value or original...).

    Since I always want to change the color space to match the color in CS4 space I would like once again able to set as default. How can I do this in CS4?

    It is in the color settings (Edit > color settings). Change the RGB color strategy to convert RGB working. Uncheck the appropriate (or all) checkboxes in the politics of color.

  • Cannot change multiple colors for the life of me

    Hi there-

    I'm VERY new to photoshop and have tried to change just two colors in this stupid picture now for about five days. I know it is rudimentary, probably for most users.

    I have searched extensively online and experienced the replacement color and adaptation to "replace color" tool under the image.  I'll try to join the front and the picture after I was able to come up with.

    Essentially, I want to just replace the red and green to orange and black.  Orange I have is a very specific pantone (I have numbers, RGB and CMYK that I would use).  If possible, I would like to keep the shading... I think that's the biggest problem.  The colors are not uniform.

    Anyway, if it will take me a lot of time it's fine, I just don't know how to do and have all the edges and look to correct shading.  I can't find an online tutorial that shows even how to clean an image after you change its color to make it look professional.  I'm going nuts.  It is a job application and if you know how to do this and can help me - thank you!  Help!uranium_explosion1_original.jpguranium_explosion1_black and orange.jpg

    With a hue adjustment layer you can easily change the colors on this image while maintaining the shadows. I selected Greens on the menu drop down and move the brightness slider to the left.  Then, I selected the Reds and moved the Tint slider to get an orange tint.  Finally, I added a levels adjustment layer to increase the contrast.  I know, however, how to obtain the specific orange hue you want. I look forward to reading more specific solutions.

  • How to protect yourself on: configuration values change by third-party tools?

    Many installers for third-party tools change firefox settings.

    Things like addons, start pages, new pages tabs, search enignes of firefox are changed without me having a chance to stop them. Why? What can I do? Trustwhorthy the tools (or at least the tools that were worthy of confidence a year ago) to do this.

    Thanks in advance for your help

    Bookmark addon Search reset, you can use it to set Firefox default search parameters to their values if anything spoil them

    I say favourite because it install reset settings and to uninstall.

    As FredMcD ays save things manually or using an addon or utility. Save your profile or at least the prefs.js file. Or be even more proactive create and backup your own user.js file prefs important that be messed with in there.

    You could go even further and lock prefs with a .cfg file, but aimed more generally deployments companies often using the addon of cck

    Three things I can think of:

    Your document must be in RGB mode.

    Layer blending mode should be set to Normal

    Masks are grayscale. If you select the mask, you cannot apply a color.

    Always check your tab at the top to see if what you choose is RGB or grayscale.

  • How do I reselect the type to change.  I have a text template that I want to, but when I try to select it with the text tool always creates a new text layer.  How to change the type of the layer in my registered design?

    How do I reselect the type to change.  I have a text template that I want to, but when I try to select it with the text tool always creates a new text layer.  How to change the type of the layer in my registered design?

    OK, Bob. This give a try.

    First, open a new file and make sure the background is white, not on Transparent that I suspect you have currently defined.

    Then, type your copy. Your layers panel will then look like the top of this picture...:

    and when you drag the text on the image layer, it will look like the lower part of the sample above.

    You can then position the text layer with the tool move

  • How can I change the color of the pen tool?

    Hello

    I struggle to see the grey line used by the pen tool when you create a path. Is anyway to change its color?

    If not what other things I can do everything by pulling the paths to make it easier to see the path line I draw?

    Thank you

    Maurizio

    It is said that keep Anti Alias guides and paths turned on in preferences > Performance > Advanced allows, but I have never noticed any difference anyway.   You use a display of very high resolution by chance?

    You will know that color the way movies between full black and white full according to the background color, but if you use a screen high resolution and the BG is just a few share points and on the other 50% gray, then that won't help much

    Not sure CS6 about, but I know that CC has brushes square by default under all of the predefined settings. See catch with the toolbar options below:

    I don't think that hardness can be adjusted either so be aware of this.

  • How can I change the color of ink for the pen tool?

    Hello everyone,

    I sign a document in Acrobat.  But the color of the pen is red. I want to change in black or blue.  I have looked around the menus but can not find how display.  He is probably right under my nose somewhere, so I'd appreciate any help.

    Thank you!

    According to the official help site.

    "Ink signatures use the default color of annotations pencil tool. To change the color of the signature, click the pencil tool on the tools of comment & Markup toolbar. Then choose tool default properties and change the color on the appearance tab. »

    I had the same problem, locate your question along the way.  Finally, I stumbled on the above.

    I tried to find a better way to access the color of the pen tool, but it's the only way to change it.  I understand that this software is not supposed to be Photoshop or whatever it is, this method of changing the color of the pencil seems completely arbitrary at best.  But, on the other hand, at least it can be done.

    I hope that this answer am you in time to be useful again!

  • How to change the color of a vector without turning pixelated icon

    Hello

    It is probably quite a simple question, but I can't seem to find a specific solution to my question anywhere. It would be nice to get some tips!

    I have an account with Flaticon, and they offer PNG, SVG, EPS, BASE 64 and PSD options for icon graphics. Now, they are all black, but I need them in color.

    So, I opened them in Ps, changed the color (Hue/Saturation and Chromakey... tried also the color replacement tool, but that did not work), saved as a PNG image (like I need the background transparent and placed in my InDesign document. However, when it is placed in my InDesign document, it seems pixelated.

    Does anyone know why this might be?

    Thank you!

    This isn't how it will show printed, it will show even better than that. Try to go file-> the Adobe PDF presets-> [high quality printable]

    This should give you a better idea of the print quality (although sometimes pdf viewers display things a funny little too XD)

    PNG is good if you make a raster image that needs a transparent background. But yes, you can copy and paste vectors directly in Illustrator in InDesign and InDesign it will retain as a vector including being able to change it. Tool pen InDesign and selection tools are substantially the same as Illustrator.
