Are there script commands to manipulate "Horizontal/Vertical Constraints" of slices in a line plot image display?
No, unfortunately these features are not exposed to the scripting language. (Status GMS 3.2)

Is it possible to make some smooth movement with a picture (or anything else)? An acceleration, deceleration...
I know we can use keyframe geometry to move an element but the movement is not smooth. The goal is to add some easing (ease-in / ease-out / ease-inout...) in a pictures slideshow.
This "bouncy ball" example is not really smooth:
https://github.com/mltframework/mlt/blob/master/demo/mlt_bouncy_ball
My use is with the command line on a linux server, I do not use any Kdenlive or shotcut.
The bouncy ball example is not intended to show smoothness or easing. The examples are basic intended to get people to walk before running.
MLT Property Animation defines "smooth" keyframes. In order to make something move, you need to pick a filter such as affine that supports animated position properties. Then, how you define keyframes and their types depends on whether using the API or a property string value (command line, XML). When using the multi-value string format, you use ~= instead of = between the time and the value. For example with the affine filter:
transition.rect=0~=0/0:100%x100%;100~=45%/45%:100%x100%;120~=50%/50%:100%x100%
Now, smooth keyframes alone do not provide easing, but you can add one or more keyframes towards the target (ease in) or leaving the target (ease out). The smooth keyframes simply help make the curve instead of you having to add many keyframes to smooth it out yourself. Think about drawing a curve with an illustration program. If you only have a straight line tool that connects at points, you need many points to make a smooth curve - the more points, the more smooth it will be. Now, if you have a curve tool, then you only need a few points. The Catmull-Rom spline used by MLT smooth keyframes was chosen for simplicity: It draws a curve through the points given.
As is often repeated, the easiest way to learn how to use the filters and their properties is to mock things up in a video editor and view its MLT XML output. Keep the project as simple as possible to keep the amount of XML to look through shorter.
When I use gnuplot I make a multiplot with 2x2 Pics. They got all the same lines with something different in there though. Thus I want them just one line title for all of them. When I scale on on below of there it resizes that special plot. Any Idea how to archieve it properly?
Thanks!
There is a patch recently added to the gnuplot sourceforge site (patch 611 here) which allows the addition of explicit margins around plots while keeping the plots the same size.
If you don't want to patch and build gnuplot yourself, you probably have to resort to setting margins manually or in a semiautomatic way, as I have done before.
I would like my Scatter graph I am making with Core Plot library to show Y value near every point relative to X data.
I looked at CPTTestApp project from Core Plot examples, but I simply don't get it. First I thought the secret lies in
-(CPTPlotSymbol *)symbolForScatterPlot:(CPTScatterPlot *)plot recordIndex:(NSUInteger)index
method and I have implemented it in my project. Yes, I got points drawn, which is nice, but I found out this probably has nothing to do with values being shown near points....
This suspicion was confirmed when I opened Candlestick demo from Plot_Galley_Mac demo. There is no method from above and it shows numbers nicely!
If anyone can, please, help me. Otherwise, I would like to thank developers for sharing this library with us. Beside over usage of NSDecimal structure and a bit thin manual and reference data, this is fabulous project.
You're looking for "data labels". CPTPlot has a number of properties that control the built-in labeling functions:
labelOffset: distance between the point and the label
labelRotation: rotation angle
labelTextStyle: text style used to draw the labels
labelFormatter: number (or date) formatter used to format the labels
labelShadow: shadow properties applied to the labels
If the built-in labels don't meet your needs, you can create your own. Implement the -dataLabelForPlot:recordIndex: datasource method and return the desired label for each point. Custom labels can be any CPTLayer so you can make anything you want—text, images, or any custom layer that you create.
I have a requirement like applying texture pattern to the 3D bars in 3D Barchart using ireport. I am able to see the texture pattern in the default JRViewer. But when I take the PDF from the same report, I cannot see the texture pattern instead I can see a transparent 3D bars.
Can someone have a solution ?
with a little research we found the answer. There is an option in the iReport for the charts called renderType. We need to set this as svg(Scalable Vector Graphics).
So the texture pattern will apply to the PDF also.
The disadvantage of using this is - The PDF file size gets increased.
I was looking at http://www.msnbc.msn.com/id/26295161/ns/weather/ and noticed that the flash map is provided by bing and have a custom color scheme. I have a similar need to show maps with a black & white colortheme, is it possible using their api or have they made custom tiles ? (doesnt seem feasible to provide tiles for alls maps on all levels :)
If you are not wedded to Bing maps, you could look into Mapbox, which provide maps based on OpenStreetMap in any style that you desire.
This question is still not answered and even if it's kind of old, I think it matters.
In fact, they're not using different tiles or a custom tile scheme. You can see those in the network inspection tool.
Since they're inside a Flash application, they can easily change the color of the image using filter on image (ColorMatrixFilter) and changing dynamically on the client side the rendered colors.
Well now some years later you can: https://msdn.microsoft.com/en-us/library/mt823636.aspx :-)
(I got here by looking for some sample styles and thought I add the link for anybody else finding this question)
Perhaps a custom tile skinner is that you need: http://rbrundritt.wordpress.com/2009/11/27/bing-maps-custom-tile-skinner/
In this example, the author changes the color of roads using ColorMatrix and ColorMap:
The two key methods used to transform the colors
consist of using ColorMatrix or a ColorMap. By
using a color matrix all the colors on the tile
can be changed within a couple lines of code. Using
a ColorMap allows you to change one color at a
time. This is useful if you only want to change a
few colors on the map.
