Cyril, thank you so much for the thorough explanation. It was very well done. I especially appreciated your explanation of the averaging technique of getting the grayscale value. - John

Paul, thanks for the link. I’m going to watch some of the other videos that are suggested. I’m trying to wrap my head around some of the algorithms in the code. Maybe I’ll catch on and maybe not, but figuring them out is a great mental workout.

After 73 years and a devastating head injury it may not have anything to do with attitude. Those days are long gone for me. Getting up each day and opening my computer to push into a new programming concept is about all the attitude I can muster these days. For me, finding something in the documenta...

I didn’t try it myself because I don’t understand the concept of palettes and how they function. I have often used the forums to see if someone knows how to do something that I don’t understand. Thanks for the work you did. I will keep playing around with it.

I notice that there is a pallet attribute in the export command. If I define the pallet with monochrome values, do you think that would work?

Greetings All,

Is there a way to either . . .

. . . change an image from color to black & white within livCode or
. . . export a color image as a black and white image

Thanks in advance for any help you might offer.

Kind Regards To All,
John Miller

What I really want is to either drag the side of the stack and have the height of the stack increase proportionally, or stage the bottom and have the width increase automatically.

When I resize the stack, first I want the image to expand or shrink maintaining its original height to width ratio. Then I want to maintain ten pixels between the right side of the image and the right side of the stack. Also maintain a margin at the bottom equal to the height of my navigation button...

Here is my code: on resizeStack put the topleft of cd image "Open Notebook.jpg" into tlXX put the width of this stack - item 1 of tlXX - 10 into wXX put the height of this stack - item 2 of tlXX - the height of group "Navigation Buttons" - 34 into hXX put 590/801 into w2hR -- ORIGINAL WIDTH TO HEIGH...

Greetings All, I have a stack that contains an image. When I resize the stack, I would like the image to grow or shrink while maintaining the original height to width ratio as well as a set margin at the left and bottom of the stack. If I drag the stack from the side, the image grows past the bottom...

Ah a newbie mistake. I forgot that closing LiveCode also closes all the sub stacks and that you have to open them. Thanks, Richard. You've made my day.

Greetings All, I am using LiveCode 9.6.9 (rc2) on an intel MacBook Pro. My stack has a button that shows/hides a substack used for my app settings. When I first created the substack, the "show/hide" feature worked fine. I quit LiveCode and came back to my project the next day. No matter what I do, I...

Greetings All, Since there was no response from anyone to my last post, I moved on from mergav. Does anyone know if mergAV is supposed to work in Livecode 9.6, or has work on it been discontinued? Using "cameraControl" scripts, I have successfully . . . . . . created a controller that shows a previe...

Greetings All, I am writing a program using a Powerbook Pro (2019) with Mac OS 10.15.6. My program needs to access the camera to record a video. I have used the mergeav script sample mentioned in the other forums to turn the camera on and record a movie to a file. It all works great. Some of the for...

Hello LiveCode Coders, I am experimenting with different PDF options. The print to PDF function in LiveCode makes a simple two page file that is 2.5 MB. If I use the print command and save to PDF the file is 128 KB. When printed there is only a slight loss of clarity with the smaller file Is there a...
