Question

Is the L8_ARGB8888 image format supported for Shapes widget? If not, will it be in the future?

Let me preface this question by saying I appreciate the new L8 (indexed) color support for many of the widgets. This includes the support for L8s in dynamic bitmaps.

I attempted to use an image formatted to L8_ARGB8888 in a shape widget. The code compiled, but when running on the simulator I received the following assert:

0690X00000AsD78QAF.png

The painter for the shape is not instantiated as an L8_ARGB8888, but a PainterRGB8888Bitmap as seen in the gui_generated Screen1ViewBase.hpp file:

0690X00000AsDCwQAN.png

Does the shape widget support the PainterARGB8888L8Bitmap? If not will it support it in the future?

I found that this also happens when trying to paint a line, circle, or circle progress with an L8_ARGB888 (using PainterARGB8888L8Bitmap).

I am not getting responses.

I created a simple project with an image formated to default (not L8_ARGB8888). Placing this in a shape in the TouchGFX Designer, it works fine. Then I added a copy of the shape (named differently) and formatted it to L8_ARGB8888.

I manually added this shape and set it's painter to PainterARGB8888L8Bitmap. The code compiles, but I get an assert in the AbstractPainterARGB8888 (which is the base class of PainterARGB8888L8Bitmap).

A little bit more digging and I did find that this painter asserts this when it's not compatible with the framebuffer:

0690X00000AsNGZQA3.png

But, according to the L8 article (https://touchgfx.zendesk.com/hc/en-us/articles/360009793299-Using-the-L8-Image-Format)

L8_ARGB8888 should be supported in BOTH Framebuffer formats:

Am I missing something?

Still no input from anybody. Some help would be appreciated.

I created an image without transparent pixels and added it as the image for a Shape widget. When I set the Image Format to RGB565, the code runs fine.

But if I set the Image Format to L8_RGB565 (no transparent pixels this time), I get the same assert message.

Bringing to the top

Still waiting for an answer on whether or not the Shapes widget supports L8......

They do in the sense that we have the following painters:

PainterRGB565L8Bitmap
PainterRGB888L8Bitmap

Martin, I noticed you did not include L8 with alpha (L8_ARGB8888). Will this be supported for the Shape widget in the future?

Is there an example available of PainterRGB565L8Bitmap or PainterRGB888L8Bitmap being used with the Shape widget?

I formatted an image to L8RGB565 using the TouchGFX Designer. Then I used this image in a Shape widget (within the Designer). However, in the gui_generated Screen1ViewBase.hpp file, it is creating an instance of PainterRGB565Bitmap (not PainterRGB565L8Bitmap setup in the Designer):

touchgfx::Shape<4> shape1;
 touchgfx::PainterRGB565Bitmap shape1Painter;

I do not understand why it is creating a PainterRGB565Bitmap when the image is formatted to L8RGB565. Can you explain this?

@Martin KJELDSEN​ 

I am just checking if the fix for this will be included in the next TouchGFX Release?

I ran into it again and then I remembered it is a bug in the TouchGFX Designer.

At least there is a work-around. =)

And...any idea when the next release might be?

Hello FBena.1,

Sorry but I don't really understand your answer. What is LCD8bpp_LUt8.h ? Where do you find it ?
