My Logo plugin


BPP_MyLogo plugin is intended to apply own logo to the video recorded or broadcasted to network. Plugin allows to load logo in the following formats: BMP, JPG, GIF, EMF, WMF, TIFF, PNG, ICO.

For the users of operating systems Win98/ME/2000 available only loading of logos in BMP format.

Dialog window of plugin settings

You may choose logo both individually for every channel («Setting per channel»), and one for all channels.

Plugin BPP_MyLogo supports loading of animated logos in GIF format both with transparent background and without.

When applying static picture it is best choice to use PNG format. This format allows to save pictures with alpha channel. In contrast to GIF and ICO formats, where you can select only one color that will be treated as transparent during the output of the picture, alpha channel allows to set the level of transparency (semi-transparency) individually for every pixel.

The setting «Transparency» set the level of transparency of the whole logo, in addition to that set in the graphic file.

If GIF or ICO doesn't contain transparency color, and also if the picture is, for example, in BMP format and you need to make some parts of picture transparent, then you may do it directly in plugin. For this you need to switch on the appropriate option. You may either set the transparency color explicitly or automatically by choosing the color of top left pixel as transparent.

The logo can have arbitrary size and may be scaled at wish from zero to the full screen size. However you should overestimate that and load a large or heavy weighted pictures as logo, because on channel switching the loading of large files, for example in JPG format, may take a notable amount of time. When preparing the logo it is preferable to choose it's size relative to the maximal frame size – 768*576.

On changing the stream format (frame size on recording) the logo saves it's proportions relative to the width and height of the video window based on aspect 4:3.

If a certain channel doesn't use logo, then you may hide it (the setting «Show logo») or turn off the loading logo for that channel at all.

For simultaneous show of two or more logos on the screen you need to create several instances of BPP_MyLogo plugin in Plugins folder by renaming the original file BPP_MyLogo.dll, for example in the following manner:
BPP_MyLogo_1.dll
BPP_MyLogo_2.dll
BPP_MyLogo_3.dll
……………………

Then you need to add each instance of plugin to the list of plugins for preview or recording and setup each plugin separately for it's own logo.
