Replacing System Images

[alexmihh]

What is wrong with this statement of mine, where I replaced a standed "SysatemHappyFace" (and the statement worked) with my own little GIF file, which does not work. I verified the file exists. I tried the slashes in the other direction -- no change -- did not work. And two "nulls" also did not work.

drawImageRelative(0, vBounceHILevel, "d:\alex\open.gif", null, Image.RIGHT | Image.ONTOP);

here are notes from PaperBroker.efs:

// SystemHappyFace is a builtin image type. These are documents in the EFS docs/ref guides
// You can also replace SystemHappyFace with a filepath to a gif/jpg/bmp on your computer
// eg: c:/somefolder/picture.jpg
drawImageRelative(-50, 50, "SystemHappyFace", "EFS:ImageCallBack", null, "ImageTag");

guessing here..

because I have not had a chance to try this. these are my initial thoughts..

A. the file needs to be in the same directory as the other images
B. there is no need to include file extensions in the call

I'll try it later..

B

A) " ...as the other images" Well, if you are refering to the system images. they are not in any directory in esignal, so this answer does not make sense.

b) "there is no need..." well that would be strange, and it goes against the notes in the esignal-provided efs example (Paperbroker.efs) and article #1796


Here is info from EFS article #1796

*************

eSignal Graphics Functions.

- drawImageRelative and drawImageAbsolute

drawImageRelative(xBar, yValue, Image, Url, Flags, TagName);
drawImageAbsolute(xBar, yValue, Image, Url, Flags, TagName);

The drawImage functions allows users to display any "user-defined" image or an image from a set of system images. Images are different than "Shapes" in their content. Images contain items such as "happy faces", "Check Marks", "Circles" and other common image files. The drawImage feature is ideal for Non Trading System display functions.

drawImageRelative allows placement of images onto charts that are relative to the active real-time chart. This means that the images move/scroll to the left as new bars are formed on the chart.

drawImageAbsolute allows placement of images onto charts that are fixed and do not move/scroll to the left as new bars are formed.


Parameters

xBar - Refers to the bar index (bar number) where the graphic is to be placed.

yValue - Refers to the Y location of the image - or price value where the image is to be placed.

Image - refers to the image type to display on the chart.

A system image can be used, or an image on the local file system can be referenced (eg: c:/someimage.bmp"). Supported image types are GIF, BMP, JPG, PNG, …

Notice how even this information is inaccurate with the extra (or missing) quotation marks in the filename.

Does anyone here have any hrlp on this? I can not get this to work, and esignal documentation is scanty

Hello alexmihh,

I have not been able to get this to work in build 738 either. I've reported this bug to our development team as EDL #21966.
